What octane is everyone running on their cars? I know the minimum is 87 octane, with 91 recommended and 93 recommended for M cars.
I’ve ran 87, 89, and 93 octane and have felt no performance difference. Also, I don’t hear any knocking on any octane thanks to the knock sensors.
Car is a g20 m340i with a b58.
Your car is smart. You won’t feel anything like that. But if you did actual benchmark measurements you would likely see differences. Or if you logged it as well for timing corrections. And some BMWs 91 minimum.
