BMW M3 Forum (E90 E92) - View Single Post - Is it worth it to get a mixture of octane 100 and 91 gas once a month?

Hey All,

I have read through a lot of the gas threads and was wondering if treating my new baby to a tank of 93 octane (mixture of 100 and 91) is better for the car over the long run? or does it not matter.

By the way, I live in California where the gas is only 91 and select 76 have racing fuel octane 100 fuel.

What do you all do?

Thanks.
