Best pump gas in California?

blacksapphire440i · 03-19-2021, 02:31 PM

I'm wondering what would be the best pump gas in Southern California. Would name brand gas stations like Shell, Chevron, Mobil, and 76 carry high quality 91 octane fuel? I have heard that California isn't really known for the best quality of fuel.

No such thing as high quality 91 in California. In fact, you guys have to run the lower ACN (Arizona, Cali, Nevada) maps. If you have ethanol near you, switch to an E30 map.

I can wait 'til BM3 adds ethanol sensor compatibility for the B58. I can't afford race gas and I can't be arsed to mix my own E30.

I used Chevron and Costco 91 octane gas without any noticeable differences or issues. Costco 91 is of course less expensive.

I run e50 mixed with Chevron 91.
