I use Mobil1 10W-30 in my TII. A while back I did a little investigation on this because I wanted to use RedLine synthetic oil in mine but found out it was not a good idea. Mobil1 seemed to be near the top of all stats that I read online. To my knowledge, 20W-50 is a heavy oil for high heat or race applications but I can't say they were wrong. :yinyang:

I heard or read somewhere that synthetic oil is not a good choice for rotary engines because it does not burn off as well as standard oil and needs to be able to. Does anyone else have information on this mystery?

Yes. Synthetic oil is FINE for rotarys. Every friggin shop recommends it... I don't know who the hell keeps passing along this goofy *** info. Get synth. Use it. Love it.

I use Mobil 1 synth and I'd be more than happy to take pictures of my guts when rebuild time comes..
