Does anyone know what octane # the civic needed?

Oh and I drive about 100 miles per day.

first of all, i think you're a cheap bastard if you just don't want to buy premium because your car deserves it,

basically, high compression, low grade gas= detonation; er bye bye b-series,

and secondly if you put on that many miles, why don't you just give up the whole tuner scene and get a car that has good fuel econonmy.
