PTFE stands for Polytetrafluoroethylene. PTFE is a synthetic fluoropolymer that has many desirable characteristics including outstanding chemical resistance, having one of the lowest coefficients of friction of any solid, and being super hydrophobic.

Are there oils with which Tufoil Engine Treatment should not be used?

Tufoil should not be used with glycol-based oils.

Why should I use Tufoil Engine Treatment instead of other engine treatments?

Tufoil Engine Treatment has been tested by the U.S Government at the National Bureau of Standards. Their results prove that the surface friction of Tufoil (.029), makes it the most slippery substance known to man!

How often should I change my oil?

We recommend you change your oil and filter every 3,000 miles. However, many of our customers find that their oil is still clean at this point because of Tufoil’s ability to cut friction and wear. They will then make the decision to extend oil changes accordingly.

How much Tufoil Engine Treatment should I use?

We recommend 8 ounces of Tufoil as an initial treatment when you change your oil. (This would be for the standard 4-5 quart crankcase…less for smaller engines.) After this initial treatment, just 4-ounces of Tufoil added to the crankcase at each oil change is sufficient. The basic guideline would be 2 ounces for each quart as an initial treatment and 1 ounce per quart at each oil change after that.

What is HinderRUST?

HinderRUST is a one-of-a-kind solvent-free rust stopper and lubricant that uses a proprietary PTFE technology to protect metals. Corrosion is annually a billion dollar problem and HinderRUST‘s engineered approach to surface film management protects surfaces against oxygen and moisture. Key to its success is the HinderRUST‘s ability to spread and wick into otherwise unreachable areas, thereby making it perfect for wire ropes and cables and hard-to-reach areas on equipment and machinery.

What is rust?

According to Wikipedia, rust is stated as this,

“Rust is a general term for describing iron oxides. In colloquial usage, the term is applied to red oxides, formed by the reaction of iron and oxygen in the presence of water or air moisture. There are also other forms of rust, such as the result of the reaction of iron and chloride in an environment deprived of oxygen, such as rebar used in underwater concrete pillars, which generates green rust. Several forms of rust are distinguishable visually and by spectroscopy, and form under different circumstances.[1] Rust consists of hydrated iron(III) oxides Fe2O3·nH2O and iron(III) oxide-hydroxideFeO(OH)·Fe(OH)3”

According to NACE, formerly known as the National Association of Corrosion Engineers, rust causes billions of dollars in damages each year. Not only is it unsightly, untreated corrosion weakens metals and causes permanent damage.

How does HinderRUST fare with salt water?

HinderRUST has several advantages over other rust stoppers on the market. For one thing, HinderRUST uses no solvents. That means it doesn’t evaporate away like many other rust inhibiting products. For another, HinderRUST is engineered to create a barrier between surfaces and outside elements such as salt, moisture, and oxygen. Those two things make HinderRUST extremely good at providing protection from corrosion in all conditions, even in coastal areas.

One of the biggest problems in our factory is machines jamming because of rust. Does HinderRUST work well with manufacturing equipment?

Yes! Not only does HinderRUST prevent rust from forming or spreading, its lubricating properties help free up areas prone to freezing or jamming.
