It went on to say that the only reason 100LL has a high octane is for those mentioned turbo charged or high compression engines. Does this mean that 200HP and 300 HP engines can use auto gas. I know a Franklin engine dealer that has been using auto gas in his 200HP engines for years. He also informed me about a Moony Club that uses auto fuel in all of their aircraft. He recently returned from a conference that involved A/C fuel providers and related to me how in the near future the only fuel available will be unleaded leaded car gas with a few extra additives for altitudes. Does this mean that all along aviators using non turbo engines have been over paying for the use of 100LL when they could have used auto gas? **************What's for dinner tonight?

IF I remember correctly (50% chance of that) the manual required 91 (or maybe 90) octane . Engine ran fine, plugs stayed clean even at the low power I ran a lot of time while skimming the beach.

With up to 10% ethanol in the gas, there are untold things that can happen to your airplane, including dissolving gas tanks, rotting fuel bladders, hose breakdown, and more. I am currently running a test on the effect of ethanol on my gas tanks. But, if your mogas has ethanol, you may have more than detonation for a problem.

I would like to see data from people flying 200/300 hp engines. I only know one Franklin dealer that says uses it in his 200hp aircraft and claims he has had no problems. **************What's for dinner tonight? Find quick and easy dinner ideas for any occasion.
