um, from what i've noticed, the higher octane the better my car runs (daily i use 89 octane, not premium and not regular).... when i go to the track i 1) change intake filter, 2) use premium, 3) add octane booster... the higher the octane, the cleaner the gas actually is (which is why it costs more), which means it will burn cleaner... on some cars you are told to use premium because of this (like the integra GSR and civic SI, on the dash you can see "PREMIUM ONLY" .... so, you decide for yourself.... but i'm going to keep doing what i do when it comes to gas.....

the reason why most cars (like the si, gsr and type r) need premium is to prevent detonation. Higher compression = higher octane levels. IT has nothing to do with the cleanliness of gas. In fact, all gas should be used what its really for, that is to CLEAN. leave the powering to methanol.
