Danny,

Why mix the fuel? The engine manual for my engine, the O-320-D1F, 160 HP specifies 80/87 octane fuel. What is to be gained by mixing?

The real problem is getting auto fuel without ethanol. Moisture will combine with the ethanol effectively sucking it out of the fuel and laying it at the bottom of the tank. Without the ethanol, the octane is lowered. Ethanol may or may not also eat the coating off of the gas tanks. I have seen this happen.

3 years ago, many auto gas stations in Michigan sold fuel without ethanol but not any more. Last year I tested the fuel at 12 gas stations. All had changed to a methanol mixture. The only 3 airports that I have been able to find that still sell non-ethanol auto fuel are in Marshall, Mi, Chesapeake, Va and Barnwell, SC.
