Propaganda cow pies My 96 Integra GSR "requires" premium gas according to Acura, it had 9.5 years of 87 octane regular gas while I owned it and drove for a couple of hundred thousand kilometers, never had a problem.I don't take it easy with the car, but I don't abuse or lug it either, i.e. wait until the engine is warmed up before driving it hard.Modern engines have detonation sensors to "listen" to detonation under heavy, and the fuel control computer will retard the ignition spark just a bit to reduce/eliminate the pinging.I can only speak for myself that a high strung GSR engine lived quite happily on a diet of 87 octane gas, and felt as strong the day I sold it as the day I bought it.
