If your car was burning pistons it wouldn't have been driving it for long. The only reason higher octane gas is ever needed is if your car is detonating (and again, if it was, you'd probalby be rebuilding it by now). What is your compression ratio? Burning more octane than you need is a waste of money and gains you 0 horsepower.
