Tufoil Engine Lubricant is Guinness Book of World Records certified as "The World's Most Efficient Lubricant." Slipperier than Teflon to make engines start easier, run cleaner, faster, and longer. Tufoil is a super-suspension of micro-miniature PTFE particles and soluble Molybdenum, permanently suspended in oil. All moving parts become coated with PTFE particles which reduce friction and wear and will not clog filters or oil openings. Safe for all gas and diesel engines. Tufoil has a pure synthetic base of the highest quality possible. The magic in Tufoil is the incredibly tiny size of the PTFE particles suspended in your oil.


These photos below are taken through a Scanning Electron Microscope and compare the particles in Tufoil with the size of a human hair:


Tufoil’s suspension particles are .5 to.05 microns in size so it mixes beautifully with your oil and can’t clog up your oil filter.




  • Your oil is changed into a highly efficient engine treatment
    with an extremely low surface friction

  • As your engine runs, the Tufoil-enhanced oil coats
    your engine, filling in the “nooks and crannies”

  • Faster cranking speed under all weather conditions

  • Better gas mileage

  • Increased horsepower and acceleration

  • Extended engine life

Why should I use Tufoil instead of other engine treatments?
Tufoil engine lubricant has been tested by the US 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 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.

Will Tufoil engine treatment affect my car’s acceleration?
Yes. Many engines tend to lurch and hesitate when the accelerator is rapidly depressed. Tufoil dramatically reduces the metal to metal drag under these high shock stress conditions.

Can I use Tufoil with my boat engine?
Tufoil works well in marine engine.  It should be used in the same manner as automotive engines.  It is also used in the lower unit gear box where the propeller is located.  Tufoil contains rust inhibitors that will help to protect a marine engine when it is shut down.

How does Tufoil work with diesel engines?
Quite well. Independent tests show that Tufoil increases the cranking speed of cold diesels by 9.6%. Naturally, easier starting means that your battery life should be greatly extended, as well! Users report startling acceleration with diesels using Tufoil.

Can I use Tufoil engine lubricant in my differential?
Yes you can. Use about one part Tufoil in ten parts high grade differential oil. It'll run cooler. Tufoil has no known adverse effect on posi-traction clutches.

Will Tufoil improve my fuel economy?
It will. Reduced friction means better fuel efficiency with Tufoil. In spite of the wide variations of engines and drivers, independent tests have shown significant improvement with Tufoil of well over 5%!

How does Tufoil impact fuel injection?
Fuel injected engines are self adjusting, automatically idle themselves back when the lubricant is improved with Tufoil, just as the carburetor would have done.

How does Tufoil affect my idle speed?
On older engines, it is not at all unusual for the idle speed to increase when Tufoil is used. If the engine block has warped or has serious internal friction  problems, the improvement with Tufoil can be quite dramatic. It will be less noticeable in loose engines that are in tip-top shape.

Does Tufoil prolong engine-life?
You can literally "double the life of your engine" by using Tufoil regularly! Most people consider 100,000 miles normal for their car. If you use Tufoil regularly at every oil change, you can expect at least 200,000...that's not uncommon! Better gas mileage, less repairs, together with longevity of the engine really add up quickly.

Does Tufoil engine treatment work with motorcycles?
Tufoil works extremely well in 4-cycle engines that have a separate sump for their oil (never mix with gasoline. We get glowing reports of smooth, cool operation with wet clutch bikes. 

What about my new car warranty?
Your new car warranty will not be effected by using Tufoil. We do recommend that you run your new car between 5,000-10,000 before you start using an engine oil additive like Tufoil.

Will using Tufoil help with an engine that burns oil?
Many old engines show signs of oil burning. Tufoil can help in some cases by freeing up partially sticking piston rings. There have been some dramatic improvements reported from the field where Tufoil freed up the rings and they started working properly again. However If the rings are cemented solid in their grooves or the cylinder is scored, no lubricant can eliminate the smoking.

Will Tufoil harm my oil filter?
Not at all. The PTFE particles in Tufoil so small, they pass through the filter as if it wasn't even there! Bulk filters that use the big wads of cellulose or edge on toilet paper rolls, filter fine.

Does Tufoil work with older engines?
Yes. However, If you have an old classic that ran on oils before 1950, we recommend taking the engine apart and physically cleaning the sludge out of the crankcase and out of the valve covers before using Tufoil. A high detergent oil can stir that material up and cause problems.

Will Tufoil help during hot weather starting?
Tufoil helps prevent the clamping of hot parts and you will find hot starting much easier. New laboratory test data shows that engine oil runs 42% cooler with Tufoil.

Will Tufoil help during cold weather starting?
The Canadian Government tested Tufoil at their cold regions lab in Kapuskasing and found an increase of nearly 10% in cranking speed! Their tests also showed an improvement in fuel economy during cold weather operation.

Can I use Tufoil with synthetic oils?
Tufoil mixes with all synthetic and mineral oils used in automotive engines!  If in doubt, you can check compatibility by warming 1 ounce of Tufoil and 10 ounces of any oil and leave for 24 hours.  If there is no settling, it is compatible.

Should I use Tufoil in my transmission?
Tufoil is too slippery to use in automatic transmissions. The oils in them need to be a bit grabby or the clutches won't work properly. In manual transmissions, about one part Tufoil in ten parts high-grade transmission oil will make them run cooler and shift smoother.

How does Tufoil work with turbo chargers?
Turbo-charged engines work extremely well with Tufoil in the crankcase. (Don't forget! When you shut your turbo engine off, to idle it before you shut down. If you don't, any oil will be cooked in the hot bearings.)

How does Tufoil affect engine wear?
Tufoil stands head and shoulders above the rest. We have run thousands of abrasion tests in our lab over the last 25 years and no other oil additive performs close to Tufoil. For results of these tests call us and we'll be happy to send them to you FREE of charge.

Can I add Tufoil to wheel bearing grease?
Wheel bearing and chassis greases benefit from the addition of Tufoil. Don't use too much or the stiffness of the grease will be lost. It will become too fluid. Mix about one part Tufoil to ten parts grease. Mix thoroughly so the final product is uniform. Remember! In disk brake cars, the disks get very hot due to braking, not friction from the bearings. If you use too much Tufoil, the grease's melting point can drop too low and cause it to run out of the bearing.

I've been using TufOil for more than 20 years in cars, trucks, lawn mowers and snow blowers.

The 2 things I noticed most were that all the engines lasted longer (particularly the small 1s) & started easier, in cars & trucks the mileage improved.

2006 Ford Crown Victoria 89000 miles - went from 18.8mpg to 19.2 in two tanks of gas. Runs a litttle smoother. Good product, worth it if you have an older car in decent shape, with high miles. It won't solve all your problems or make your car run like new, but it will help.

Tufoil Engine Treatment
November 21, 2011
I have used this treatment in my 2001 Ford Explorer Sport and went 368,000 miles which they say is unheard for the 4.0 liter 6 cylinder Ford engine. Along with Royal Purple motor oil, you will get your moneys worth from your vehicle. That's like 22 years of mileage in 10. So I bought another Ford 2002 Expl. Sprt and using Tufoil again. This is the best engine oil treatment out there. I add it every other oil change. Which with synthetic oil is 12,000 miles. So every 24,000 miles I use it. Works wonders. And the price from Auto Barn is another good thing.
