The difference between premix and OMP is the two stroke oil you w= ould use in premix. The OMP is using motor oil with all the disadvantages it= has when it gets into the combustion chamber. Also, you can not use synseti= c oil in the engine when using the OMP. 
There is a lot more i= nfo available in rotary engine related discussions on the internet.
fwiw.

Subject: [FlyRotar= y] Premix vs OMP

I now have 2 engine cores. One is set up for premix a= nd one is set up for OMP.  (I of course just purchased a set of SS brai= ded OMP lines before acquiring this 2nd engine)

My search o= f the listserv (2006-2010 results) shows that overall premix yields a better= distribution (at least for the RX-7 engines with 2 OMP lines). 
Is the general consensus still that premix is a better dis= tribution? Still recommending .7oz to 1 US Gal?

Thanks,
