It is much better IMHO to mix the oil with the fuel.

I'm convinced, based on extensive operation in rotorcraft, airboats and race
cars, that using the oil injection for this type of operation is fine.  I
suppose it also depends on what oil you use, and whether you expect to
operate over 7000 RPM.  I plan on using Amsoil synthetic, and you'll note my
deep, 8-qt oil sump so I can meter oil to the rotors for many of hours
before needing to add oil.  We'll see how it works a few years from now.

Buildup of deposits is more likely in cars doing short distance trips (lack
of warmup), and is contributed to by deposits from the gasoline.

Yep, that's about how long it takes. Far be it for me to disagree
with Dave Atkins. It is kind of obvious if you disassemble a couple of
engines. Oh well it is always a good idea if conventional wisdom is tested
again from time to time. Are you going to run EGR too?

BTW tomorrow I get to try out my new walnut shell blaster cleaning
a couple of really dirty rotors with stuck apex seals :-)
