No, the oil actually helps seat the rings properly! Has a dual purpose with the additive.

The 7-77 will be bogged down IMO if you run it under 5,500 on the ground. After break in you can run a 24x10 around that rpm or a 22x12 at a little over 6,000 and hit the power band nicely. Just my experience. If you run it in CDI it'll do 6,400 rpm on a 24x10 with methanol which I run it at... and handles it just fine (though I certainly don't pin it full on a dive). I guess depending on the plane and for a more "scale" flight you'd want less RPM but on my 32lbs Corsair, I bring the RPM up.
