Status: offline 		In my shop i have something called tefflube. i have been using it as an after run oil. and after using it in my sand master it ran more powerful for a while. has anyone tried using teflon in there fuels? i know after adding it to the oil of a car engine you actualy have to turn down the idle. we tried it and the engine idled about 450rpm faster. it was a product called frictionshield. any experiance in this?

But the concept of teflon in engine lubes has been largely dismissed as being worthless. A great many *truly* independent (as opposed to those often trotted out by the snake-oil manufacturers) tests have shown that there's nothing to be gained by using a suspension of teflon in oils when used in engines.

It should also be remembered that these oils are usually not designed for 2-stoke use. If you burn them, chances are they'll contaiminate the glo-plug element and/or produce some nasty toxins (as teflon does when raised above a certain temperature. Indeed, quite a few cage-birds have died when people have accidentally left their non-stick frying pans on the stove and overheated the teflon coating).

Status: offline 		You're probably correct Sport, although I believe that at least for awhile....the FAA did in fact approve the use of "Slick 50" in aircraft engines. That may no longer be the case as you pointed out. The Feds aren't usually receptive to the use of miracle additives.

FWIW however....you'd be amazed at how long a Lycoming or Continental engine will run without oil. Those engines are designed to produce power (and save your a$$) until it is no longer physically possible. They will literally destroy themselves in an attempt to get you back on the ground safely. Incredible designs, and I have spent thousands of hours with my butt in their caring hands.

Actually they did approve it after a test run of only a few hundred hours. Then there was a crash, fortunately it was really a forced landing with only minor damage. The NTSB found that the teflon restricted the screen starving the engine of oil. The FAA then banned the product.

Thats mostly a byproduct of large bearing surfaces and low engine speed. Also very thick 50 weight oil helps. Actually I have a very poor opinion of GA engineering especially with regards to safety and keeping up with modern tech.

I don't know what it would do to an engine but it will make a real mess of your clothing if you get it on you.

Just about what I expected -- If it is too good to be true, then it usually isn't true.

Thanks for the heads up.

Cheers,
