BMW owners manual requires 91 octane minimum. Sure you can run regular, the computer will adjust for it and you'll have less power, but that's not what BMW designed for. If following what BMW designed makes me a sucker, I guess I'll be a sucker. Being in California I don't have to worry about rust in my gas either.
