ever heard the saying "a rotary will knock once, and only once"
wanna know why? Cause pinging, knocking, whatever, kills engines. Granted you may get away with a little on a honda, but why would you want to? They have cast pistons that break ringlands like they're perforated, and if you ask me, paying another 10 cents per gallon is cheap insurance when you've shelled out a few G's on a motor.
