I agree, but I would not suggest this method unless you are sure that you know what spark knock sounds like. You can destroy an engine with uncontrolled or undetected detonation (pre-ignition, spark knock, knock, pinging, and detonation are all terms for the same thing). It will start by breaking the upper ring lands off of the pistons, then it will break compression rings leading to scored cylinder walls and sometimes it will put holes in pistons. Detonation will usually occur first when the engine is under load (almost lugging).
