That seems to make more sence. I am a bit familiar with the gas law (in physics) that states for a relationship between volume pressure and temperature of a gas. (I cannot recite nor name the formula).

I also beleive that a by-probuct of the higher flash point, the resulting explosion takes place at a higher temperature as well, yeilding more horse power, and better efficiency. And also leaves the comustion chamber cleaner.

I swear that I didn't stay in a Holiday in Express last night - LOL

Re: Premium-v-regular gas

Well I guess you guys told me.. Ok premium it is.

I think that knocking I hear is my knees hitting together when I'm trying to follow tdannar out of the mountains.

This is a great forum, for a great car.
