I began using Tufoil in November, 1989, when my 4WD 1988 Jeep Cherokee with 6 cylinder engine and 5 speed transmission had about 40,000 miles. I bought this vehicle new; for several years it was my only vehicle which I used in my sales work so I drove 1,000 or so miles many weeks; I changed the oil and filter myself using Mobil 1 about every 10,000 miles plus adding the recommended 4 oz. Tufoil each time. Also, I changed the oil filter every 5,000 miles and topped up the oil. In 1996 at 300,000 miles, my technician recommended we replace the oil pan gasket due to leaking; with the oil pan off, he asked other technicians to look up at the underside of the engine and estimate mileage; they estimated 30,000 to 50,000 when it actually had 300,000. The head has never been removed; no internal engine work has been needed.

In 1999 I participated in my first Jeep Jamboree at Land Between the Lakes; I lost a rear bumper; soon I began a few off-road upgrades; later my son and daughter joined me on other Jamborees so we've had fun on a total of 6 so far including the 15th Ouachita in 2004 with my Mom who was 84; this unstoppable Jeep has provided lots of father/son and father/daughter quality time. And, yes, we let ourselves get talked into 3 "red neck mudslinging events" also. Well, I did wear out a pressure washer because I like a clean vehicle.

Ziebart provided rust protection soon after I bought my 1988 Jeep so it has little or no rust. Also, I had it totally repainted the original Colorado Red a few years ago; I say it looks great!

Then in 2001 my daughter decided she wanted to attend a school in Minneapolis, MN. She and her boyfriend found the biggest U-haul trailer in town; they packed it so heavy I used low-range to get out of our up-hill driveway and proceeded from Nashville, TN, to Minneapolis with my wife fearing we would breakdown any mile; the Jeep engine with Tufoil never missed a beat; we got there and returned home safely.

If you attended the Dream Cruise in Detroit during August, 2008, you likely saw my red Jeep with signs on the Yakima rack proclaiming, "600,000" miles. That was a bit of an exaggeration but I can now truly document over 600,000 miles; I even have three log books with record of every expenditure, etc.

I thought I would write you regarding your TufOil product. I have been using this product since 1974. I bought a 1976 Olds Cutlass and put over 250k miles on it before selling it to a family member, before I sold the car, the only problem I had had was a blown radiator hose, had to pull the heads and replace the head gaskets. That was the only time the motor had been into other that regular tune-ups and oil changes. The family member I sold the car to put another 100k plus on the car before the timing chain gave up. When we broke the engine down, the bearings and cylinder surfaces were still like new, and when we checked the wear with a micrometer, had less than ..003 in the cylinders, and the bearings looked as good as the new ones we installed. I have a 1985 Ford F150, 300 CID in-line six engine, going on a million miles, this is the original engine and it has been overhauled three time. I use your product in all my vehicles, including the differentials and manual transmissions, even my riding lawn mower. I would recommend this product to anyone. Thanks for a great product.

My 6 cyl 1994 Jeep Grand Cherokee has just past the 273,000 mile mark. I have been using Tufoil in the engine along with Mobil one synthetic oil since I purchased the Jeep. I religiously change oil and filter every 10,000 miles. I have never had to add oil between oil changes. I used Tufoil in my 1967 Ford Mustang before I purchased my Jeep. It got up to 200,000 miles before it was stolen. My Jeep is still getting 19mpg in city driving and 24 mpg on the highways. I even started using your light oil pen dispenser of Tufoil in my roller skate bearings.

Thank you for a wonderful product. I will let you know when my Jeep turns 300,000 miles.

I put Tufoil in my 1998 Durango. Highway mileage jumped from 16.6 to 18.5!!! I have owned this car for nearly ten years, and I NEVER got even close to this mileage. I now plan to use Tufoil in all my cars, as well as in my lawn tractor and generator. Thank you for a great product.

I started using Tufoil in 1989 in my 1987 Ford F-150 pickup, when it had 50,000 miles on it. It has the 300 six engine. The same vehicle now has 216,000 miles AND SHOWS NO SIGNS OF STOPPING!! It has the same original piston rings, and never failed an emmissions check.

I have used it in the manual transmission and rear axle and never lost a bearing, they are original! I started usuing it in my 2005 Ford Escape too! :)

For someone considering a first time Tufoil purchase: I have been using Tufoil for almost 20 years! Trust the maker, and my word as a user of Tufoil, it works.


We have been using Tufoil with ALL of our vehicles since my dad was 30 (he is now 60) and I'm 26.

1979 Buick LeSabre (still running today, sold to a friend at work; over 195k miles)

1991 Buick Regal (185 k miles+, sold to a friend at work, still running strong, does not burn oil, still at 26 / 17 MPG!)

1999 Chevrolet Venture Van (120k miles and going strong, drove from NC to CA in 3 days, 24.3 / 18 MPG!)

2001 Trans Am WS6 (46k miles and soon to be making 600RWHP, 26 / 17 MPG!)

2005 Malibu LT (65k miles and going strong, 33 / 22 MPG!)

2006 Malibu Maxx LT (71k miles and going strong, 30 / 20 MPG!)

Absolutely NO oil leaks or engine problems from any of the above cars.


I just wanted to say how happy I am to have found you. I havent been able to locate your product for years, but with gas prices as they are now, well I guess I looked a bit harder this time.

The first time I used Tufoil was in my 1972 Dodge 4X4. It got 7 mpg. After putting it in the engine I noticed the rpm went from 700 at idle to 2200. I had to readjust it. The fuel economy went from 7 to 9, then I tried it in the transfer case and differentials, it went from 9 to 13mpg and it just seemed to run much smoother. The truck had 350000 miles on it when I traded it on a new one.

I used it in a number of other vehicles, 1974 Chrysler-went from 14 mpg to 19 mpg and 525,000 miles before the body rusted out. I also had a number of 1982-1990 Dodge 15 pax vans we used for airport transportation. They averaged 12-14 mpg before tufoil, 15-18mpg after. One went at 250,000 miles (the driver kept driving after it blew a radiator hose and ruined the engine after 50 miles) the rest did 500,000+ miles, and one went 860,000 miles and we drove it to the junkyard still running fine.

Not being able to find your product I tried a number of others, I didn't notice any changes in the way the vehicles ran.


After using and selling Tufoil for 18 years I felt that I had to write to you both about your excellent product. I'm in my 20th year of running a 3 bay auto repair shop. In my second year I was introduced to Tufoil by my local supplier (already having read about Tufoil before, but was not available in my area I did not hesitate to buy it for my vehicles and to offer it to my customers).

Right from the beginning we observed the changes after about a week. After doing only oil changes and adding Tufoil the engines would idle at a good 200 rpm more than before (with carburetors at that time the idle would have to be readjusted, now a days the car's computer does it automatically for us so we and the rest of the public do not notice this change any more).

We have 90 to 95% of our customers using Tufoil; all satisfied and when they change cars they automatically ask us to put Tufoil in their new or used automobile that they just bought.

Many of our customers' vehicles are over 10 years old and have from 250,000 km to 350,000 km in them.

I see other garages in our neighborhood changing engines regularly compared to us it only happens once every 8 years or so and usually it is a new client's engine which had not been treated with Tufoil.


One of our courtesy cars has over 480,000 km on it with the original engine; hardly takes oil between oil changes and the manual transmission (also original) has no bearing noises and now grinding syncromeshes. Another one has over 300,000 km and has the same story, (I'm sure the bodies will let go before).

About 12 years ago we did only an oil change with 8 ounces of Tufoil on a Hyundai Sonata with an automatic choke carburetor. A couple days later the customer phoned me to say that the car would fast idle on cold start at about 3300 rpm instead of 2500 rpm. We verified all and had to bring down the cold fast idle. That's an amazing difference of friction at cold!

We've had 3 vehicles run DRY on oil (BMW's and a PORSCHE 928) with 150,000 to 250,000 km's on them and driving an average of 4 to 8 km. After repairing broken oil pans, etc, the engines never took more oil or would knock at cold or hot.

I have customers telling me they notice their engines run smoother and take less fuel.

Being specialized in the maintenance, repairs and modifications of approximately sixty Dodge Vipers, I wanted to let you know that we, Premier Chrysler Inc., endorse your product "Tufoil" during the maintenance of our customers' Dodge Vipers. We have been using your product with confidence for the last 8 years.

In February 1996, I purchased a 1995 GMC 3500 1 ton Vendura cargo van, with a 6.5 Litre diesel engine, from Georgian Pontiac in Barrie, Ontario. It was brand new.
To this day I still drive this van. I'v ealways used it for my small distribution business. This past week it turned over 790,000 kilometres [490,883 miles]. Yes, Seven Hundred and Ninety Thousand killometres. And the engine has never had any major repairs done to it. The heads have never been removed. Based on what I have been told by former owners of 6.5 Litre diesel engines and service personnel at Georgian Pontiac, the average life span of 6.5s is usually around 300,000 kilometres [186,411 miles] at best.

Well, I have 790,000 kilometres on mine and I am aiming at 1,000,000 kilometres. It still runs so well that I am confident I will see the 1,000,000 kilometres. I have used Tufoil Engine Treatment from the day I did my first oil change on this engine. Every 5,000 kilometres I have changed the oil in my engine and always added an 8 ounce bottle of Tufoil Engine Treatment each time.
And I am truly convinced that Tufoil Engine Treatment has played a major role in reaching such high mileage with my engine.
There is no doubt in my mind that the use of Tufoil Engine Treatment has been a major contributing factor for the long life of my 6.5 diesel.

I also use Tufoil Engine Treatment in my family vehicle, my daughter uses it in her car, and so does my father-in-law in his.


It was indeed a pleasure to speak with you today – especially in recalling our conversations of over 13 years ago when I was about to write an article for an organization called the ZR-1 Registry regarding state-of-the-art lubrication. I remember featuring Castrol Syntec as the oil of choice and strongly recommending the use of Tufoil – a product I had used since the mid 1980's. Therefore, here is my testimonial. Although it dates back over nine years – I believe it is extremely relevant to this day.

In June of 1992, I purchased a new 1992 ZR-1 Corvette – which as you may recall featured a GM first – a production dual overhead cam V8 called the LT-5, designed by Lotus Engineering and assembled by Mercury Marine. The engine displaced 5.7 liters and produced 385 BHP – which at the time was considered a real beast. In late 1996, I was determined to have the engine significantly upgraded and by early 1997, with over 48,000 miles, I had the LT-5 removed and shipped to an engine builder in Minnesota. Once there, they tore the motor down in order to replace the pistons, rods, crank, valves and numerous other components necessary to increase the displacement. As it turns out, ordinarily, all these removed components – especially with this mileage – are typically discarded. However, because I had been using Tufoil since the motor had 5,000 miles, the engine builders found that all the removed engine components were in "as good as new" condition – and clearly because of their honesty, accordingly issued me a credit of several thousand dollars. I unquestionably attribute this significant cost savings to Tufoil.

Thank you for a terrific product and I look forward to meeting with you sometime soon so we can compare "inventor" war stories! All the best!

Just a note to let you know how pleased I am with the use of your product Tufoil. I am in the sewing machine repair and sales of home and commercial units. I find the machines run smoother for a longer period of time using Tufoil. I also use Tufoil in my 2000 and 2005 Toyota Avalon's. My 2000 runs whisper quiet and is silky smooth no matter how hard I push it. I also noticed my 05' shifts into 5th gear at 47 MPH instead of 50 MPH- after adding Tufoil. My gas mileage in the 2000 remains at 22-24 City and 28-30 Highway. On the 05' mileage is 26-28 City and 33-36 Highway. I've checked with the computer more than once to be sure I'm correct. I've used Tufoil for more than fourteen years in all my cars. Thank you for your interest.

Powerflow Ltd were recently commissioned to complete the annual major maintenance at Kourarau 'A' and 'B' hydro stations owned by Wairarapa Electricity. This involved a partial strip down of the 'A' station turbine and bearing maintenance and in 'B' station a shaft and bearing re-alignment.

The Hydro Plant

The plant consists of a 700kW twin jet twin runner Pelton wheel at 'A' station and a 220kW twin jet single runner Pelton wheel at 'B' station. These were installed when the station was built in the early 1920's. Both have large flywheels and direct drive to 3500v alternators. There are four large heavily loaded ring oiler plain white metal bearings to each turbine alternator system ranging in size from 100 to 200mm diameter. The two turbine bearings have their oil reservoirs cooled by copper coils conveying water from the turbine penstock.

As all bearings were being drained, flushed and filled with new oil it was decided to add Industrial Tufoil to all 8 oil reservoirs. It has now been two months since the Tufoil was added and the plants put back online. As most of the bearings are still original from the time of installation and some are getting close to their tolerance limits, it is imperative to keep further wear to a minimum.

Results of Addition of Tufoil

The most dramatic result has been the very significant reduction in bearing temperatures both in the turbine and alternator bearings. Having been familiar with the temperatures prior to the addition of Tufoil at around 30 to 45 degree C, I was extremely surprised when I went back to the plant and found the temperatures had dropped to around 20 to 25 degrees, just barely warm. Our estimates are that we are saving in the order of 2 to 3 kw in bearing friction alone per plant and the subsequent reduction in wear is likely to see the plant perform many more years of faithful service.

Apart from just bearing temperatures there are two characteristics that can indicate a reduction in bearing friction in plants of this size. They are (1) ease with which the plant can be turned over by hand after shutdown and (2) the amount of water required to get the turbine spinning from start-up. In both instances the comments from plant operators have been that the turbines can be turned over more easily by hand and require a much smaller opening of the main needle valves to start the turbines spinning from rest. In the past, 'A' station would require 2 people at least just to move the turbine shaft and now this can be achieved with one person. A similar result has been achieved at 'B' station.

With such a successful result with the turbine and alternator bearings it is now intended that the oil in the hydraulic governors should also be treated with Tufoil and this is anticiped to further reduce maintenance and make significant cost savings. I look forward to being able to report on positive results from the governor treatment and only wish I had taken more specific temperature readings before adding Tufoil so I could have given you exact figures for the temperature reduction.

Approximately fifteen years ago, I had added eight ounces of Tufoil to my car while I was attending an automotive school and the results were quite impressive. The engine was running perfectly before adding Tufoil and afterwards it ran smoother, quieter and had better acceleration. Within twenty minutes of the addition of Tufoil to the engine, the idle speed of the engine increased one hundred RPM. After lowering the idle by restricting fuel to the engine, I realized that significant fuel savings could be realized as well as a reduction in engine wear. I started testing Tufoil on various automobiles and diesel engines in cranes and generator sets. For the most part, all the cars showed improvement in acceleration, engine noise, idle quality, lube and fuel consumption.

Meeting with much skepticism, I started testing on diesel engines that exhibited high oil consumption and excessive crankcase pressure. Generally the feeling was that it couldn't hurt so why not give it a try. The first engine I tested was a Detroit Diesel series 353 engine in a Grove crane that was blowing the dip stick out of the tube and spraying oil everywhere. It was determined that the unit had to come out of service for an overhaul but I convinced my superiors at the time to give Tufoil a try. After changing the oil and filters I added 10% Tufoil to the crankcase oil and ran the engine for twenty minutes. The crane was operated over the weekend and Monday morning we went out to see if there were any changes in the engine. The operator noted that it started much quicker than he could remember. While he ran the engine at full throttle, I pulled the dipstick out and put my face in front of the tube. I then turned and looked at my boss and asked if he could see any oil. He didn't. The crane ran fine for seven more years and was removed and overhauled only after a bad fly wheel necessitated removal of the engine. Since that time, I was approached more frequently to give it a try and time after time we saw impressive results.

The largest Detroit Diesel engine, the 16-149 had similar results delaying an overhaul in a tug boat over one year allowing us to schedule it at a more convenient time. We now have 149 engines running over 30,000 hours with oil consumption meeting OEM specifications for new engines. Presently, RTC operates 15 tugboats and all have Tufoil either in there reduction gears or engines. We presently operate the electronically controlled Detroit Diesel 149 DDEC engines with Tufoil and expect to reach all time record high hours between overhauls.

Most advertised oil additives are full of empty promises and that fuels the skepticism that additives are a waste of money and can be harmful to your engine. I recommend Tufoil wherever you need to get longer engine or equipment life as well as lower fuel consumption. If your still a skeptic, try using Tufoil where you have nothing to loose, you never know. You might be impressed!


We race a Speedway Super Saloon, Chevrolet small block, large displacement engine, developing over 700 horse power, with high torque figures. The previous season when racing had finished, the engine was dismantled and found to have a large amount of wear, so much so it was necessary to rebore the block and regrind the crank.

The engine was reassembled with lower compression pistons, leaving us with a 13.2 ratio. We were still worried that the same thing may happen to the engine this season, we looked at changing the oil brands but felt that the oil we were using should still do the job, and perhaps an additive would be the best way to go. After speaking to other competitors, we decided on Tufoil.

Our race car using Methanol fuel, gets a small amount of fuel pollution in the oil, so the oil was changed every four meetings and Tufoil was added. After this season, when dismantled, the engine was found to have no wear, in fact we could have reassembled it and run it again, and that's after thirty meetings of hard racing. Lowering the compression would have helped, but I'm sold on Tufoil, as this played a major part.

An interesting thing we noticed was the oil temperature, which had always been around 200 degrees, was now around 180 degrees with Tufoil, telling us straight away that we had less friction.


I began using Tufoil at 39,500 miles in November 1989. Since then we have enjoyed this 1988 Jeep Cherokee on (6) Jeep Jamborees plus three (3) other off-road events. All the while it served as my business vehicle as I sold long-term life insurance and recruited agents across the mid-south. Many weeks saw over 1000 miles traveled. In 2000 my daughter and her husband-to-be loaded the largest U-Haul trailer they could find which we, using this Cherokee, towed from Nashville to St. Paul, Minnesota, where she attended school for one year; my wife just "knew" we would break down any minute and be stranded but the Tufoil trained engine purred ahead with never a miss and returned us safely to Nashville showing over 400,000 miles on the odometer. The Jeep now has over 565,000 miles and completed another business trip to the mountains of North Carolina during the recent winter weather. Come visit us to ride through beautiful Tennessee back roads and off-road whenever you wish!


Really tired of reading "all-additives-are-snake-oil-BS!" comments in various blogs! Possibly most...definitely not "all!" I began using Tufoil around 1979 — 37 years ago! Wife had gotten a new Subaru with 4-opposed engine — idling engine shook slightly — added Tufoil — twitching immediately disappeared! Have used in everything from old beater pick-ups to a new XR4Ti. Added to a differential. Cured a glitchy manual tranny. Put a couple ounces in my shop oil cans. One word: smoooooth


I first discovered Tufoil in 1987... and have been using it on every vehicle I have ever leased or owned since. Even my younger brother and father have been using it since then. Tufoil proved itself in the mid 90's when my father's 1965 Rambler Ambassador experienced oil pressure pump failure during a short trip around town. Within a few minutes of the dash indicating no oil pressure, the rockers were seriously loud, but noticed that there was no change to the engine temperature. He proceeded to drive home, constantly monitoring the engine temperature. The 30 minute drive was successful. With very loud lifter noise, due to the lack of oil, and the engine still operating at normal temperature, my father was convinced of the power of Tufoil. The car even started right up the next day. He eventually had the oil pump replaced and had a head job that was needed for some time to alleviate prior lifter noise... and continued using Tufoil until the car's last day, sometime in mid 2017 or so when he sold it. The elements had taken a toll on the vehicle's body with excessive rust. But, the engine was still running strong. He and I believe that if it wasn't for the many years of Tufoil use prior to the oil pump failure, that the car would have not survived that trip. Today, I still use it on my 2000 Lincoln Navigator and my wife's 2015 Nissan Frontier. Tufoil is part of every oil change.

I have a 3 month old 2017 Nissan Titan 4X4 SL. Just wanted to let you know that I added Tufoil to my front & rear differentials at a 1-20 ration, and 1 ounce per qt. to my engine, just one week ago. My mpg for doing the same home-work-home-town driving in one week jumped on the first tank of gas from 17.6-to-19.0 mpg during that 400 mile range. That’s an increase of 8%!

I have been using Tufoil for over 25 Years, first on a 1987 Acura Integra on which I put 327,000 mi. followed by a 2000 Honda CR-V which just hit 320,000 mi. and is still running great thanks to Tufoil!

Tufoil has saved me thousands of dollars in new car costs & repairs.

I started using Tufoil in 1989 when my new Honda LXi got to 1,000 miles. I added 8 oz. Tufoil and switched over to Mobil 1. I could actually hear and feel the difference about 1/2 a mile down the road. I remember is feeling smoother. I changed the valve cover gasket at about 190,000 miles and the tarnish was minimal and I use Tufoil in everything! Great stuff!


My first experience with Tufoil Lubit-8 was years ago via McMaster-Carr (Lubit-8 in handy dispenser, which became a "go to" lubricant). I spread them around the Cleanroom toolboxes (I worked in the Semiconductor Industry for over 20 years, and now with Hi-Tech Company utilizing Semicon environment).

Years later, it's still my personal and professional "go to" lubricant. I also just found 11 y.o. dispenser stashed away and forgotten, and don't see any difference between the contents with the one ordered 6 mos ago. Thank you for the superior product!


I received a free sample of Gun-Coat along with order of Hinder-Rust some time ago. It took me a while to get to use it, as I'm a Gun Lube junkie: you name it, and I likely have it/tried it. So recently decided to give it a try, while contemplating returning to the (best known brand's) CLP or run a combination of brands/solutions. Tried Gun-Coat on semi-auto rifle and pistol, even before I ordered and received the entire Gun Care Kit, so haven't tried the grease yet. From way it cleans to glass-smooth slide and bolt carrier action: an eye opener. I could save a lot of money trying your product first!

As I get ready to move, I'm finding things in the garage that I haven't touched in years. I found some fishing rods and tried to take the pieces apart, but they were firmly stuck together. Not even a wrench would get them to move! I put a couple drops of Lubit-8 on each connection, let it sit for a minute, and the pieces came right apart. Next up will be the pieces of the hammock frame!


I used your Tufoil Lubit-8 for my grandfather clock this weekend. It worked GREAT getting into all those tiny/narrow spaces and gears!!!


I have used Tufoil in my SAAB vehicles over the years. I have had several different SAAB cars over the past 40 years, and am currently driving a 2007 Aero 9-5, which has had Tufoil added at every oil change, as did the other cars. I am very satisfied with the Tufoil. I even put a bit in my old Honda lawn mower and the snowblower. Mobil 1 and Tufoil have been my routine for many years. If it has an engine in my family, it gets Tufoil and Mobil 1.


My mechanic just changed the oil in my Saturn. I had added Tufoil in December 2019. Because of the "no essential travel" I got a 6 month oil change instead of the standard 3K. My mechanic told me the oil was so clear it was like it was new and to continue adding the Tufoil...so I am!


One of the weapons that I shoot is a Smith and Wesson M&P 22 pistol. A great handgun but like most 22 semi-automatic pistols, there can be, from time-to-time, an issue with the cycling of the slide. Well, I recently switched from the oil that I was using to your Gun-Coat and the last three times, at the local range, while shooting over 100+ rounds each day, had zero "failure to fire or cycle" issues! Not one failure!!! My cleaning procedures did not change...only the fact that I went to Gun-Coat.

Needless to say, but I'll be using Gun-Coat on ALL of my weapons. Shotguns, rifles and pistols. A GREAT product!


My job required 2,000-3,000 miles every 2 or 3 weeks. I drove a 4 cylinder Pontiac Grand Am that had about 70,000 miles when I started using Tufoil. When I left the job, the car had 396,871 miles on the same original engine and I didn't have to do any engine work in that time!

There is NO WAY that would have happened without a GREAT engine product. Nice job, Tufoil!


I have been using Tufoil in all my vehicles since the late 70's and am one very happy user. I also use it in all my small 4-cycle engines (lawnmower, edger (30 years old), chipper (+20 years old).

In February 2016, I purchased a stock and very original 1939 Ford Fordor Deluxe and am using Tufoil in the engine, transmission and rear end. The last 2 items also use 140 weight hypoid gear oil, GL4 (non-corrosive to brass). The engine is the original non-modified “Flat Head” V8 and runs perfectly. I’ve read a number of forums that mention ZDDP should be used in flat tappet motors (of which this originally was and is presently). This is especially true of engines specifically built for racing.

I use straight 30 weight non-detergent oil since I have no oil filter. When the car was made there was no such thing as detergent or multi-weight oils. My intention is to maintain the car as it was in 1939, but with the added advantage of Tufoil.


I had used Tufoil for many years, both on my cars, lawn mowers and at my last job during some product testing and development. I had spoken to your company’s owner at the time, Frank Reick, on 1 occasion and he sent me a sample of some very slick compound to test on a medical device component at my job. I used the engine treatment while stationed at Plattsburgh AFB in northern NY where the temperature got to -30F. It did a great job and it allowed me to start my car under some very severe conditions without a block heater or dipstick heater. I never had an engine problem while using your product. Years before this, I tried a synthetic oil (Eon 11) while stationed in Denver, CO and I experience lifter sticking after running the engine for a short period (the valve job was very costly). This is why I am leary of synthetic oils.


I have been using Tufoil for around 30 years now. My last vehicle was a 2003 Chrysler Sebring with nearly 300,000 miles on it. All the vehicles I have used Tufoil in (except leased vehicles that I had to turn in before they went over a prescribed mileage limit) have exceeded 200,000 miles before I sold them.


Just wanted to let you know I have been using your product around the shop. I had two fire extinguisher system cylinders that came in I had to dismantle. On the top of them were Allen screws that were rusted in, I put some of the Lubit-8 on them and let it sit overnight. Also there was a metal head cover on the cylinders that were rusted on and locktighted into place. I was able to get everything broke loose and I know it is because of the Lubit-8 that I used. I now have a new best tool in my tool belt. I don’t know if you ever heard the commercial for Fran’s Hot Sauce were the Grandmother say “ I put that %^#$ on everything” well that is my new motto with your product. It really works as you describe it.


Been using it since my 2007 Acura Type S was new, currently has 174,000 miles. At valve adjustment, they looked brand new and nearly no wear. It burns no oil at all. I've always used Tufoil in my vehicles, even back in the early 90's, my 89' Dodge Shelby Daytona with Original Turbo has 190,000 miles. A great product!


Absolutely LOVE all the Fluoramics products I have purchased. Truly outstanding consistent performance. Tufoil for Engines, Lightning Grease, Lubit-8, HinderRUST, Gun-Coat, all great products!


Use it. Love it.


We use Lubit-8 on squeaky door hinges in the house and no more squeaky doors!


Used Tufoil every oil change on a Saturn Sedan, got over 150k miles on it. Now using Tufoil on a 2006 Kia Sportage, every oil change now at 202k miles.


I have been using Fluoramics Teflon Oil Supplement since 1970's in my Dirt Bikes, Motorcycles,Trucks,Cars ,every oil change! Best Oil additive and engine and Transmission and axle Protection in the World!


I started using Tufoil back in 1975. I had heard an ad for it and decided to give it a try. The second time I started the car - 72 Charger/318c.i. - it sounded like the starter was "free wheeling". That sold me right there. Got 286,000 on that car and I've been using it ever since. My best story was the 84 Shelby Charger that I drove to 406,000. All the vehicles I've used Tufoil in have been 200K plus for miles driven. I now use it in my 2013 Charger which I bought used in 2019. I expect the same performance which will most likely make this the last vehicle I buy in my lifetime. All told I driven over 750K+ lifetime miles. Thanks Tufoil!


I love Tufoil and think it is liquid gold and the best product on earth. I use it in everything that uses gas – even my remote controlled little boats! I started with a gallon of Tufoil when I started driving at age 17.


Tufoil is the best engine additive I have used over the past 40 years, will keep buying thank you for creating such an awesome product.


I lived in Massachusetts over 25 years. The inventor of Tufoil lived in the town where we worked. I used it in all cars and trucks. In the blizzard of '78, I was driving from Newton, MA to Foxboro in a 1972 Chevelle with Positraction rear end. I was the LAST car on I95 South before it was shut down! I passed humps, which were snow covered vehicles and a hurricane blizzard on my back! I found the Foxboro exit via high tension lines overhead at Sharon MA., I took the exit and drove to my home, I was driving at over 50 mph on TOP of the snow, engine, tranny and rear never had an issue. One week later, we cleared 6 FEET of snow from our driveway!

I love Tufoil and I have been using it since 1985. My Father turned me on to your company in 1985. He would put Tufoil in his Chevrolet Citation II with a 2.5L Iron Duke, and I had my first car that I put Tufoil in, it was a 1981 Chevrolet Chevette with a 1.6L 4 cylinder engine. With Tufoil, I managed to get 135,115 miles on it. If you guys could send me a hat to wear, I would wear it and advertise and brag about how great your products are, which is true your products are great.


I’ve been using Tufoil for over 40 years, I use Mobil 1 and Tufoil together and have documented over 25% better fuel economy consistently. I use it in all of my cars and haven’t had a problem. In fact, to illustrate further, I used in my ’76 Special Edition Trans Am 455 w/ 4 speed and when I rebuilt it and added a few things to the engine, we discovered that the bore diameters of each cylinder were within original specs and the pistons all weighted within 5 grams of their original specs. So Mobil 1 and Tufoil work. I used to get over 30 mpg in my V6 Trans Sport Van fully loaded on the highway and sometimes over 35 mpg if I would stay under 70 mph. It is the same on any of the cars and vans I’ve had and I still use it.


I have been using the Tufoil Engine Treatment since 1978-1989 (North New Jersey)
Current Virginia 1989-2021
I have used this product in many auto/truck vehicles first initial use is 8 oz then 4 oz every other oil change gas and diesel trucks.
I have also torn down big block engines with racing/ harsh abuse and no issues found inside the motors and valve covers were very clean.


In 1986 I met Mr Frank in our Power Plant, while discussing tuffoil & it’s applications. I also ask if it would work in Automobiles, not only did Mr. Frank give me plenty of literature on Tuffoil he gave me a gallon to try! What a nice Gentleman, I loved his news letters & called him on a number of occasions. I used tuffoil in my new 1986 Nissan pickup 5 speed manual after breaking it in for 5000 miles. Was really amazed, had to idle motor from 825 rpms back to original 700 rpms & mileages went from 30 to 33 mpg. Oh yes, put 450,000 miles on it & still running good, oil still on full at every 5000 mile oil change when I sold it. Also put in transmission & Diff. - never did anything but drive it, no mechanical issues at all ! I use in all my vehicles & mowers. Car -230,000 still runs like new
Truck - 260,000 seems to run better & smother as miles pile up. Thanks Tuffoil !!! 😁

I have used Tufoil for more than 25 years. I heard about it from a mechanical engineer that I worked with. I have been using it in my 2000 Toyota Tundra since the first oil change after break-in. It now has over 302,000 miles and going strong. I think the body will give out before the engine. The engine didn't really loosen up until 60,000 miles. It hasn't changed since. It burns no oil. The exhaust pipe has a dry, light gray color with no soot. It runs great! I also put Tufoil in my new 2018 Honda CRV. The idle immediately got smoother and quieter. I get better gas mileage than the EPA estimate by a lot. I started getting 32mpg, highway or city average. At 35,000 miles, the CRV is now getting 33.4mpg consistently, highway or city average. I have also used Tufoil in other cars with similar results. If you care about your car's engine, use Tufoil. It's a great product! The money you save with better gas mileage and extended engine life is WAY MORE than the cost of Tufoil. Use it. You won't regret it.

I read a lot of testimonies, thinking this can’t be as good as what people are saying. I ask some extra questions that not on the FAQ page, just hesitate about putting it in the oil and something goes wrong with the engine. So I finally bought 1 bottle put it in my 1st car and after 20 miles my acceleration was a little bit better and idling better then after 60 miles it idles really quite and a lot faster accelerating, so this product might work I’m thinking, so the car will just get better now I’m saying and my computer on the car that shows gas mileage, it use to say 26 miles to gallon, now it read 29 miles to gallon wow! After now 150 miles on car.
I ordered a 2nd bottle for my other car and just now poured it in see what happens.
Should of found this product sooner and used it.

We applied your product to a heavily rusted folding machine feed roller chain. The chain had been stiffened by rust for over a year, rendering the machine inoperable. HinderRUST dissolved the rust, lubricated the chain and returned it to a usable state.


My little rust tests are far from scientific… I just got a few pieces of steel and applied some different compounds on them and left them down near the beach to see what would happen. I will be using HinderRUST to control rust on my old Land Cruiser from now on. I’m just a guy with an old 4WD truck trying to keep it from dying a rusty death. I want to try to keep the vehicle for as long as I can, and rust control is very important if I am to achieve that dream.

The vehicle sees a lot of salt mist/fog while camping on beaches in Mexico… Hot, Humid, constant salt mist… Tropical corrosive hell to steel… But paradise for me!

When I can roust myself to come up with a coherent and believable customer feedback blog.. I’ll send it you’re way.
Problem is, Customer Feedback on manufacturer’s websites don’t really carry too much credibility… They just seem like another form of advertising … But maybe we can come up with some method to spread the good word.


I was very excited about Eureka Fluid Film, but after using a 12 oz. can on a few spots, and inside a body panel, and 2 doors, I soon discovered that I had contaminated my car with the stuff. The stink from the fluid vapors seem to last forever (2 months and counting so far). Even worse, the smell makes my lungs and throat ache and burn every time I even got NEAR it.

I have since tried to remove as much of the vile stuff as I can, but its impossible to get rid of all of it in the hidden nooks and crannys between body panels where I sprayed it. I still have to open all the windows an hour before I get in the car to try to AIR it out.. and I have to park the car on the street because it stinks up my garage (and makes my lungs burn).… 2 months after application.

Perhaps Fluid Film is “non-toxic”, and I wore a new 3M half-mask organic vapor cartridge respirator when I applied it, but I am obviously very sensitive to it or allergic to the lingering vapors… Maybe its those lambs! I suppose the vapors will dissipate after a few more months so I can drive pain free and park the car back in the garage.. I hope so. The product is used world wide and it has been around forever, so I guess it’s just my sensitivity/allergy to it, as I haven’t heard of other guys having this kind of problem.. Lucky me.

Also, I tried CorrosionX but it is too stinky for my liking as well, though it seems to work for rust control.
Any other compound that is toxic/smelly is instantly off my list.
HinderRUST, as you know, does have an odor (contrary to what the label says) but it is not as strong, not offensive to me, and does not bother me like the others do, and the smell does eventually go away.

I know I am making a big deal about the SMELL of these products. But odors or lack of them are significant. When we are driving in our car, we are living in our car for that period of time. My recommendation to anyone contemplating spraying the entire under-body of their vehicle is: Can You Deal With The Lingering Vapors? The square feet of steel that could be coated under a car by a CPC is perhaps 3X? 4X? the size of the outline of the vehicle… Thats a lot of square feet of wet corrosion oil giving off fumes… and if it bothers you, you’ve got a problem.

Any CPC that dries to a waxy film is off the list. Waxy compounds, in my experience do not work too well when applied to rusting and sort of dirty metal… The rust seems to continue to grow underneath the wax…

Any of the other CPCs that only come in a pressurized aerosol can will not work for me, as I need a bulk fluid that I can spray inside the boxed frame and other tubes/channels under my car with a schutz gun using a flexible extension wand. I wear a positive pressure, remote AIR supply respirator so I don’t breath any mist, and I spray it outdoors on a breezy day.. with me upwind. It only takes a few minutes, and I’ll do it once a year. I’ll brush HinderRUST on the rest of the stuff that needs it.

Choosing a good CPC shouldn’t be hard for anyone. All someone needs to do is purchase some small quantities of the products they are interested in and try them out for themselves. It doesn’t cost much or take very long (unlike testing paints) and its kind of fun to see how they perform. Thats what I did, and I ended up choosing HinderRUST.

We had to replace the toilet in our bathroom. I took the caps off the bolts and realized I had a major problem. The bolts were totally rusted and completely seized. The wrench was useless here. When I took the top off the toilet, I noticed that it was stamped “1954”. No wonder! These bolts have been on here for almost 60 years! I had some HinderRUST in the house, so I thought I would try it. I sprayed both bolts and waited about ten minutes. I tried the wrench again and both bolts came off like butter! I have never seen anything like it!

This is a great product. Not only does it stop rust but it’s an excellent lubricant!


Today, our first customer for HinderRUST is a shop repairing Rolls Royces for royalty and nobility. This old customer of ours usually has about a dozen Rolls awaiting repairs in his shop. Please let Mr. Reick know that Tufoil and now HinderRUST are proudly used on such cars meant for monarchy here.

HinderRUST is causing me to chase my trash barrels around my driveway! I have two Rubbermaid Brute® Round Containers for trash in my driveway. For years, the ball bearing caster wheels have been squeaking and jamming – it was sometimes a challenge to wheel them out to the sidewalk because a frozen wheel would not allow the barrel to be pulled in a straight line.

Anyway, a couple months ago, I sprayed the casters and the wheel bearings with HinderRUST, hoping to save the rusted bearings. Now, the roll so easily that the wind blows them from their place in the corner into the middle of the driveway. This sometimes means I need to get out of the car to move the barrels back to the corner before I can park the car. These things now roll on the slightest incline. I think I need to spray them with HinderRUST to stop this barrel migration. Have you invented HinderRust yet? I did not de-rust the balls or races – I just sprayed on the HinderRUST. The barrels are out in the weather (not under cover at all).

I just thought you might like to hear that funny story. I’ll keep you posted on how long this behavior will last. Unfortunately, I did not log the date of application, but I’ve traced it to early September 2012 (figure we’re now at four months and counting).


We spent the weekend at the beach and wanted to share this with you. The air con units are located near the ocean, not directly facing the ocean, but are affected by the salt in the air. While we are away, the units are covered with a cardboard box to help as much as possible to have the units with the least contact to the salty air. The one unit has been in place for over a year and a half and has been sprayed with a WD-40 type product some four times during this period. The second unit was installed new 9 months ago and taken apart before installation, HinderRUST was applied to the inside parts and the outside cover was fully covered with HinderRUST. The results are amazing, it looks like new! HinderRUST was again applied to the outside of the unit as we left. We´ll check it on our next visit.


For the HinderRUST product, we use it on the slides and beams of our portable sawmill and have seen marked improvements through the winter months.


The boys were moving some cement bricks in the front of our house and that required a brand new wheel barrow. Well, it squeaked like crazy! I went out to read and a couple of those squeaky trips gave me a bigger headache than the one I was trying to escape. I fetched my aerosol can of HinderRUST and sprayed it all over the center of the wheels and the next trip it was absolutely silent. They boys were impressed and asked where we keep "that stuff."


HinderRUST is just beyond amazing. I live in Hawaii surrounded by salt water, the Pacific Ocean. Even with undercoatings and electronic anti-rust devices in Hawaii, eventually everything starts rusting. One day, surfing the net, I found HinderRUST, deciding to give it a try, amazingly stopped my car's rust. Usually once rust starts, it just keeps going, but HinderRUST just stopped it.


I have used HinderRUST for a tire bead lubrication 3 times now, although not a scientific test, those 3 times were the easiest I have ever done. I also treated the entire inside of the rim to prevent rust...If HinderRUST is used to treat the rim and as a bead lubricant, there would be no more corrosion. I'm in need of new tires on my truck and I'm going to have the shop use HinderRUST to mount them to see how it works.


This is a locking door knob on a temporary door. We've been wrestling with it for months, sometimes taking a minute or so to get the key to turn the lock. After applying a few drops of HinderRUST to the key, the locking mechanism now works perfectly! We're amazed at the difference!


Have had a chance to use your stuff, thought it was a little pricey for a small bottle, boy was I wrong. A little goes a very long way. I am hooked, every where I see rust bang! A little steel wool and on goes your rust protector, thanks for a wonderful product.


When a clock has not been disassembled for fifty or so years, things can freeze up on them. Specifically, the hands can stick to the shafts and tubes to which they’re attached. It can be from corrosion, rust, or just dried lubricants. The hands can be a variety of materials – steel, brass, perhaps painted or maybe ‘blued.’

My dilemma is that removing the hands is one of the first steps to the disassembly of a clock so that it can be lubricated and serviced. If I can’t get the hands off, I can’t work on the clock!

The main thing is not to damage the clock by bending or breaking the hands, or to damage the finish on the parts the solvent I use touches. I have had excellent results with HinderRUST. I just put a drop or two where the hands and the parts they’re frozen to meet. I let it soak for about eight hours, and then the hands can typically be removed with a gentle tug. Finally, I wipe the HinderRUST off the parts, and I haven’t had any etching or other damage to any type of metal, paint, or finish.


Absolutely LOVE all the Fluoramics products I have purchased. Truly outstanding consistent performance. Tufoil for Engines, Lightning Grease, Lubit-8, HinderRUST, Gun-Coat, all great products!


I have used HinderRUST S4.0 on my car door hinges and also underneath my car on any rusty areas. It works GREAT!!!


HinderRUST is absolutely the best product on the market. Consistently protects, lubricates, and provides long lasting performance. This product is available in many forms for all applications. Especially useful for corrosion mitigation where lead-acid batteries are installed.


I love your products. HinderRUST has worked great for me and a little goes a long way.

I am using Lightning Grease in my old, steel-framed Tommaso bicycle. I have had it for years and do all of the mechanical work myself, as I take the time to get it just so, while local bike shops work on volume and "close" is good enough to get it out the door. "Close" is not good enough for me, so I do the work myself. I use my bicycle greases on my guns also.


I used the High Temperature Spindle Grease to coat the roller wheel bearings (sintered) inside my clothes dryer. Works great and doesn’t melt out. I ordered this item again last night.

I am a Mechanical Engineer with a product that uses an outsourced hand-switched (a toggle) air valve.
After just a couple dozen cycles, you could feel that the valve was already losing its smooth actuation.
At about 30,000 cycles, the valve would stop working (air would leak through when the valve was closed.
Note: While 30,000 seems like a lot, but it's only about four months of use by one of our customers.
We needed to improve the life, hopefully without a complete design change.
The lubrication was a silicone grease, we washed that away and replaced the lube with LOX-8 Grease.
The life is now 800,000 cycles! That's twenty-six (26) times the life with just a lubrication change (the mechanics were not changed).


We use LOX-8 with any threaded fitting that contains Sodium Hypochlorite. Before we switched to it, we tried multiple thread sealants that would just break down and start to leak. Since we have switched, as long as the fitting stays intact, the LOX-8 has kept the Hypochlorite in our pipes and off our floors! Due to it’s success, we have started using it on other chemical pipe fittings throughout our facility.


In regards to the LOX-8…What an exceptional product! I originally reached out to Fluoramics because I had leaks on my chemical feed lines on my Sodium Hypochlorite system. After the LOX-8 resolved those issues, I applied it to my Sodium Hydroxide system and then my Aluminum Sulfate system. I no longer have leaks. I wish I knew about this product years ago. Highly recommend this product!
