Will 110 octane race gas hurt stock motor?
Will 110 octane race gas hurt stock motor? I am finally taking my car down the strip this weekend at Rt. 66 in Joliet. A buddy of mine offered me a few gallons of 110 octane race gas to put in the car thinking maybe i could gain a little timing out of it.... my questions are should i mix that with something or run it straight? and is it safe? Will I see any improvements over 93 octane? Thanks!
110 octane *unleaded* will retard the timing on your car because obviously we all know octane means resistance to burn, the higher the octane is and since your car is set to burn at a specific octane, your car will most likely retard the timing hurting your 1/4 mile times...turbo cars need race gas you dont

Most octane boosters raise very little. (Tenths of an octane raiting)

Higher octane actually burns slower, thus the reason why it helps to reduce detonation, however it should only be used in applications needing it, i.e., high compression, turbo, etc. Stock cars will typically run slower on 110 octane. More octane is better only to reduce knock, but only to a certain point, once you get to the octane that reduces knock, going to higher octane the "burn" will be slower, and thus the slower et. In theory you want to run the lowest octane that does not produce knock. As for high octane retarding the timing, not sure how that can be, octane alone does not cause the computer to retard timing, it has no idea what the octane rating of the fuel you are running is, however when it detects knock via the knock sensor it will retard timing based on the PCM tables.
