> i’m not an expert but this doesnt make sense… people run 93 because it burns better and you get more power and better gas mileage than you do with 87. i think its been proven many times over in magazines and other sources.

if you have a computer controlled car it will take advantage of the 93 octaine and give more timing which will give more power but if can run full timing with 87 octaine then switching to 93 will give no power gains
