altitiute like I said above. I lived out west (in the Idaho/Utah area) for a year (not that I'm proud of it - I didn't like it out there), and like I said I travel all the time and while I don't obviously put 93 in the rental car (to pull that out of that statement was rediculous) I am staring at a gas pump for a minute or two while I fill my rental of the week and I note the fuels available. I simply got tired of dealing with his childish backpedaling replys. I could have gone on and argued about the "half vs. minority only having 91 octane" because facts would easly dispove the "half" arguement but that wasn't the point, and he couldn't see it so it was pointless. Thank you for summing up my point very well above though.
