Tufoil FAQs

Tufoil engine lubricant has beene 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!
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.
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.
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.
Tufoil works well in marine engines. 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 protect a marine engine when it is shut down.
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.
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.
Fuel injected engines are self adjusting, and automatically idle themselves back when the lubricant is improved with Tufoil, just as the carburetor would have done.
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.

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! Fewer repairs, together with longevity of the engine, really add up quickly.

Tufoil works extremely well in 4-cycle engines that have a separate sump for their oil (never mix with gasoline). Do not use Motorcycle Treatment in a wet clutch, since Tufoil is an anti-friction lubricant. If the oil in the engine is also used to lubricate the transmission and clutch (wet clutch) do not use Motorcycle Treatment.
Your new car warranty will not be affected by using Tufoil. We do recommend that you run your new car between 5,000-10,000 miles before you start using an engine oil additive like Tufoil.
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.
Not at all. The PTFE particles in Tufoil are so small, they pass through the filter as if it wasn’t even there!
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.
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.
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.

Over the years, Tufoil has always mixed with all mineral oils and synthetics oils. Recently, however, we have seen an emergence of glycol-based synthetic oils and greases. We are mostly seeing it in high-end gear box synthetic oils for high temperature applications. Tufoil is not always compatible with glycol synthetics. If in doubt, you can check compatibility by mixing 1 ounce of Tufoil and 10 ounces of your oil at room temperature and stirring. No wait time is needed. Tufoil should dissolve right into your oil with no settling or clumping. If there is no separation, Tufoil is compatible with your synthetic oil.

Turbo-charged engines work extremely well with Tufoil in the crankcase. Bearings run cooler and quieter, plus Tufoil Technology extends bearing life.

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.
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.
You can add Tufoil to your engine oil right away. Please understand that the use of Tufoil does not change the frequency of your oil changes. Please continue to change at your normal intervals.

Tufoil is too slippery to use in automatic transmissions. The oils in transmissions 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.

Tufoil may be used in all 4-cycle engines including boats, recreational vehicles, 4-wheelers, motorcycles, and snowmobiles. It should not be used in 2-cycle engines. If you are unsure if your engine is 4-cycle or 2-cycle, please check engine specifications.
