For normal, just-because-I-want-to flying, not competition or racing, just flying for fun, what fuel is best for an OS engine? Is Morgan Omega fuel good? What about Cool Power? What's the difference between Omega and Cool Power? And for anyone interested, please advise me with my school science project. Go to Search type in "Science Project." It's posted by Graxafone (me) and it's under Engines Discussion. Thanks.

Cool power is all synthetic and omega is castor/synthetic blend. I beleive that it is 30/70 castor-syn. I use the omega for my 2 stroked because everything I have read says that the castor gives the best protection. Some say that castor will carbon up the valves in the 4 strokes but a little won't hurt.......

For everything you need to know about Morgan Fuels, go to www.morganfuel.com. I would recommend Omega, which contains some castor. Castor is an excellent lubricant and rust inhibitor.
