2-cycle oil burns cleaner than crank case oil. Richard Sohn used to make an
adapter that allowed the Oil metering pump to pull from an external
reservoir for injecting 2 cycle oil.

I finally settled on premix.

I see racers doing this on the rx7club and nopistons forums, but they
have a good reason (usually they want to run synthetic, which doesn't
burn that cleanly.

In an aircraft, where's the benefit? Run out of OMP oil and you kill
your apex seals (and maybe your housings if the apex seals break and
drag around in there...) Run out of crankcase oil and you could seize
the E-shaft. Both are bad, so you're going to have to pay attention to
your oil quantity, and dino oil works fine. So... if you don't want to
run premix, why not just leave the stock setup the way it is? At least
that way you aren't introducing a new failure mode to the mix...

Am I missing something?
