Just wondering what gas station all you california predator owners use. I have always used the same chevron by my house and haven't heard knock, but also haven't done any data logs....

With that said, diablosport states "stay away from chevron and shell". Diablosport clearly recommends Mobil, Sunoco and/or Amoco/BP. We don't have any of those in this area... it seems shell and chevron dominate. I have noticed we have Arco, which is the BP of California. Has anyone used this gas, or in general, what gas have you had good experiences with? Thanks in advance. I am running the 91/CAI tune, jet 180, with catch can.....
