I have a 98' M3 with every bell and whistle on it and I was wondering if there are any problems with using a higher octane gas such as the 100 octane low lead they use for aviation. My car is supercharged, intercooled, with an aquamist system and an obd-I conversion car, with upgraded headers and UUC straight through exhaust (with no cat. converters). I need to use higher octane gas because I am running a supercharger and chip that is remaped to use 93 octane or above. So the real question is, can I do this without damage to my engine or other components?
