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.
Get 93 when you can. In Cali, 91 is the highest available. Also, avoid mixing fuel types as much as possible. Pick 91 or 93 and stick to it.
So if I use 91 since I am in cali, it should be fine?
Yeah.
