RE: cool power fuel/after runs oils
I never used to use after run oil. I was heavily into helicopters for
a few years and it would be difficult to get the oil into the engine.
So I never did it.
I ran Cool Power 15 and always ran the engine dry at the end of
the days flying. I had two heli motors rust on me pretty bad.
One was a Thunder Tiger 36 and the other was an OS32.
Since that happened Ive religously used a 50/50 mix of
Marvels Mystery Oil and auto trans fluid. No rust since.
So I attribute the claims on the fuel jug as marketing.
Nothing more.
