I have a saito 91. I had cool power 15% nitro 4 cycle fuel, and worked great. I ran out of that, and nowI have cool power OMEGA 15% nitro 4 cycle fuel. Whats the difference?Will it work with the saito 91? Are they compatible fuels????

Cool power has all synthetic oil in it . Omega has some castor oil, 30% of the 17% total oil . They say the castor builds up carbon on the valves . no big deal I have used Omega in all my 4-strokes .I like the extra protection of the castor oil. Max H.

Both are made by Morgan. Their web site http://www.morganfuel.com has info about the ingredients. Oddly, the "regular" Omega 15% has a 70/30 synthetic to castor ratio and the "4-Stroke" blend has a higher castor percentage.

I run the Omega 15% in my Saito 82 and OS 70
and have no problems. I like Castor oil in my fuel,
old habits are hard to break.

I have used these fuels interchangably for years. I usually will switch to synthetic for cool and cold weather flying to help with starting. I try to break in the four strokes with castor oil fuel mostly for the gumming up effect on the muffler threads. This is the best "locktite" for mufflers as it stays hard with heat. I have even screwed up and mixed the two fuels together with no appreciable change in tuning.
