I have to be honest, I can't tell when wife has slipped in 87 octane exept that it is not as quick. On the open road it does not knock or really have that much less seat of the pants performance! We only put in regular once in a while so the octane in the tank is usually no lower than 89! Gas mileage is really the same no matter if I put in 87 89 or 91 (HIghest in Ca)![8)]
