Thats NOT funny! (my dad said that too)

One of the threads I read a long time ago that made me want to try it. Yes I am a sucker for advertising especially additives.
Tufoil test

I wonder what the results would be using just a moly additive.
Dupont states Teflon has no use in an engine but moly is used often and is an accepted additive in engine oil.

It looks to me like 50% snake oil at least, the Teflon part which is probably only included so they can make advertising claims like this..


I think its the moly component providing any positive results.

Slick50 used to say something similar back in the day. Everybody was using it, I tried it too. And then came numerous articles disputing PTFE effectiveness. Shortly after the market dried up.

A cool story and testimonial..

For those who say that the PTFE particles can clog up oil pathway leading to premature wear, this guy(which I have talked to)has been using Mobil 1 and Tufoil from the first oil change. The car now has 612,000+ original miles and going strong. Yes it could have gone that mileage just using Mobil 1 but this is to show that PTFE particles in Tufoil will not clog up the oil passage ways at least in this engine. Talking to the owner via email, he said he never has had an engine related problem in this car.

The Kawaski factory race team uses teflon in their oil, and they claim it gives more power (less friction), but they take apart the engine after every race. It may work for them for a few hours, but for long term use, it isn't any good. Briggs and Straton did a test with teflon in their motors, and they found it didn't work.

I don't think they all used Tufoil.

Steve, that article was to show what I bolded in my post NOT to show that Tufoil caused that engine to last that many miles.

If its got moly in it, then yes it may have some benefit. I still would not use it though....

I've used Tufoil gun oil and general purpose oil, and the motor oil product, but that ONLY in the gearbox of a SAAB manual. There it did seem to reduce shifter effort. I would NOT use it in an auto trans or in a crankcase.
The gun oil and general purpose light oil seem to work just fine, but neither are "crankcase duty".
Dupont is pretty clear about not using it in engines, and I am sure they would like to sell more of the stuff if they could. If I am not mistaken, Duppont even sells a teflon gun oil under the Remmington name.

I used to use Tufoil in my 1980 Mustang turbo, the only thing I ever noticed was the engine turned over faster at startup.

well, I did use it many many years ago, can't prove it but my hunch is that it is the reason my main bearings had to be replaced at about 80,000 miles.
