O.K. I'll bite... Why do You get more horses from each explosion???

I doubt it too. I think it was Phillips 66 gas.

the octane rating doesn't do squat except lighten Your wallet and
provide some psycological benefit (placebo effect....)
Happy motoring,

Could be. But is it possible that it is a more *efficient* motor fuel? I am in
Colorado and they force us to use this crap gas with MTBE added to it. I guess
it's extra oxygen. They used to switch to it only in winter but now I guess some
gas stations are using it full time so they can charge the higher price full

I knew right away when they would switch over to it as I seemed to use more gas
for the same amount of driving. I was thinking that maybe I could mix some of
the good gas with more of the crap gas (say, 10:1 or something) and get more
mileage from a tank. My truck was designed to use higher octane gas I believe. I
have been using about 85 octane.
