    Ok,Beat Me!! I'm guilty of running regular 87 octane in my C5!!!
    Ok,I change my oil when the oil monitor is down to less than 5% too,and sometimes thats 8,000-10,000 miles!!

    My 03 Spiral Grey runs great on 87 octane and averages 33-35 mpg on trips! I try not to run any ethanol gas though!!

    Maybe,Mines just a freak,I really can't tell much difference in it power wise than my 01 Z06 other than the Z06 rides rough and the mufflers are loud!!
    It's got so it seems to me that the Internet has created a lot more Horses A$$'s than we have Horses!

    Good to know

    Has nothing to do with the question, which is about octane, after the oil is refined, but good to know.

    There are plenty of folks who continue playing golf even after the rain starts falling. These guys never get hit by lightening. Does not mean that lightening never strikes on a golf course. Just means that just because you can do something, does not mean you should.

    The explosions which happen in an engine cylinder are pretty tricky. None of us can quite understand just how fast and how powerful these explosions occur. The octane rating of gasoline is matched to the compression ratio of the engine. GM engineers spend countless hours researching and developing these parameters. They want to give us high horsepower (read fast!) and very dependable engines.

    Premium gasoline (depending on your location in the US) is one of the ingredients which enable us to fully enjoy our Vettes.

    That is all I have right now. Boy, does this get me tired!

    AFTER FILLING UP WITH 80 OCTANE GAS, DON'T FORGET TO SAVE THE !
