I'll agree with Dick!
I don't do a "break-in" process or use "break-in" oils either.
I use Amsoil 50-1 right from the start, run my needles to max performance and do not "baby" the engine.
My engines all get excellent power and are still running strong.
Who spends time "breaking-in" their chainsaw, weedwhacker, lawnmower or other small industrial engine?
Full size aircraft engines will not usually "break-in" properly unless run hard right from the start....75% or better power.
