Well, here's one for you:
I'm a model airplane builder and flyer. My models are powered by RPIC
engines that burn alky and nitro. I have both 2-cycle and 4-cycle
engines ranging in displacement from 0.40 cu" to 1.50 cu".
A couple of years ago someone came out with a teflon based additive
that was supposed to "slick up" the internal parts of our model
engines. One of the writers for a modeling mag did an independent test
of the stuff and wrote an article about it. He took a 0.60 cu" engine
that was in good shape, ran it on a bench setup and recorded the full
throttle RPM with a selected prop. Then he ran the additive thru the
engine as per tha instructions and retested. The engine gained a
significant number revs - I don't remember how many - seeming to
indicate that the stuff worked, at least for the short haul.
Just food for thought. I still didn't buy any of the stuff; but I'm a
natural born skeptic of blanket claims.
