Tufoil Engine Treatment 4 oz.

Have used Tufoil since 1980. was impressed then and still am.Great additive to increase hp and mph. a true friction reducer.Have proved this out decades ago using a Falex machine; tribology test equipment for the evaluation of the physical properties of lubricants .Frank Reneck (chemical lubricant engineer) of Upper Saddle River, NJ invented this.Thanks for a great product FrankTribology is the science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication, and wear.cheersSouthwind Tony

I use tufoil in all my cars...Been using it since the 80s when i owned a used car lot... 11 International patents so this is a different product. I like that the ingredients are in perm suspension also.

I thought this stuff had left the building. Put it in a warm engine for proper dispersion.

I have been using this product for years. Plan on joining the quarter million mile club again with my Honda.

Good additive for the engine

THIS IS THE STUFF!!! Taken off the market for a little while and changed slightly, I still trust it with my life and car. Got 376,000 miles off an 80s 6 cylinder with it till someone stole it and totalled it. Didn't burn oil so who knows how far I've could have gone. Caution, do not use this product on a motorcycle with a wet clutch.It's true this product has gone through changes since it first came out in the early 80s and probably is not as good a quality as it was but with that being said it's still the best oil additive on the market. It's a shame that a product like this and another one named Friction Wedge were removed from the consumer these products cause vehicles to last much longer than intended by the manufacturer.
