don't put regular in your car unless u have some kind of piggy back or stand alone ecu which will redo the timing. |
Your volume statement is correct, but your conclusion about pre-detonation is incorrect. If the ECU detects pre-detonation, it will retard the timing to alleviate the knock. It's very unlikely to suffer any damage from low octane gas, your performance will just suffer.
