Wish I had said that. It would make me seem like a genius.

I am still having a problem with people running Amsoil Saber (100:1 oil) at 50:1 or lower. Once again, if you want to run a 32:1, or 40:1 mix with Amsoil then use Dominator (50:1). Amsoil developed these two oils to run in mix ratios at or slightly richer than the stated 100:1 or 50:1.

For years I have run Dominator at 40:1 in all of my engines. No cooling problems, no stuck rings, excellent compression and excellent idle with very good top end RPM. Elson (RC Bugman) provided excellent comparative information on the way an engine performs when it is heavily loaded and run for long periods of time at full throttle. Of course, there are very few of us who put the type of maximum stress on our engines that Elson did. Under our flying conditions almost any dino or synthetic oil will work fine. I still have a hard time getting my head around a 100:1 or 80:1 mix.

Good cooling air flow is far more important than the brand of oil you use.
