pretty much anything non-synthetic will be fine.

Castrol GTX has a very good long-term record of protecting rotary engines.

Modern synthetics are just fine, but are a waste of money in most cases.

If you feel like going the whole nine yards, go with redline or royal purple. I'm currently running redline and its great.

Chevron. I use it. It works.

stay away from Royal Purple. Long term use, it leaves sludge deposits. Studies have been done. You can't suspend molybdenium Dysulfide in a fluid state. It WILL settle with time. I think GTX is good and cheap. if you have money go with Redline, or Amsoil.

10w60? 5w50? sytethic + 2stroke oil/fuel mix????

This is asked weekly. Please just search for "oil recommendations" or "oil type".

Closing thread, and will be adding this info to the FAQ soon.
