    Static compression for B16 runs in 10.2 to 10.5, did you put in 89 or 98 octane?? :blink:

    BTW what kind of fuel booster are you using? (It may not be able to raise the level high enough)

    Just keep putting in 91 octane whenever possible and put in a bottle of octane booster.

    if your really concerned you can hook up a hose to your return fuel line, and drain it into a bucket or something. Just let the car idle. The fuel will drain the tank. Then you can put in fresh gas.

    What are the grades of gasoline you have out there?

    Here we have 92,95,98 & 100 octane. Compressn ratio >10 or >9 (cars with higher mileage) 98 recommended.

    Perhaps you should take this opportunity to clean out your fuel tank of any fuel deposits, gums and varnishes left by deteriorated gasoline.

    :eek: What do you live on a gas refinery and you an make what you want?? <_<


    Standards around (most of) the US are usually 87, 89, 91, 93 and once I saw 95 near Indianapolis.

    California has lower octane gas and is more expensive. As B would say, it's # 9830838338 Cali Sucks. :lol:

    your motor really shouldn't be knocking if it is stock, running just 89 octane.... is your timing advanced at all?
