I'm sorry, I didn't mean to turn this into an Ethanol discussion. Too high of compression is when you have to pull timing to run Gasoline. Since we're not talking hotrods it should okay to pull timing off the top if you keep advance under cruise and moderate acceleration right? That's what Honda does to their economy engines, the Fit has 10.8:1 and runs fine on regular. That's not 1:1 since it's an aluminum engine with a carefully designed combustion chamber but the basic idea translates.
