    If I'm putting A 93 octane race tune, would it be okay to just burn all of the regular glass out of the car until the gas light comes on?
    Should I Siphon the gas?
    Should I just put a octane buster in the gas I have?

    Any over thoughts?

    Also will I see improvements if I just put the regular gas tune in the car?

    Or just mpg gain?

    I'd just drive it until nearly empty, then fill with 93 octane. I'd expect the 87 tune to offer improved mileage.

    Drive the tank empty and then fill up with 93. I get better mileage depending on what tune I use. I get 16 mpg with my 93 Race tune and 19 with my 93 Hybrid tune. I've never used 87 octane in my car so I can't help you there.

    Yeah, I've never had to go back to the 87 once I swapped to 93 so I don't know if there's a difference. I don't expect that there would be.
