Hi,
I just bought some 25% nitro, 16% oil to run my evolution .46 on because the guy at the hobby shop said it would work. I just wanted to get a second (or third) opinion, because someone at my flying field said I should have at least 18% oil content and I was also wondering if 25% nitro might be too high for that engine.
Thanks. I'm still pretty new at all of this.

Fuel
The Evolution Engine comes pre-run and adjusted from the factory. We recommend using high quality Cool Power Omega, Hangar 9® AeroBlend™ or Power Master fuels containing 10 to 15% Nitro. The Evolution Engine has been test run using these fuels. If another brand of fuel is used, it may be necessary to slightly adjust the needle valves to compensate for the differences in fuel.

The cool power and omega have 17% oil according to the charts at
