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.
