i recently did a 900+ mile 87 vs 93 octane mpg compar-o.. i averaged 2.9 more mpg with the 93 octane. works for me. :yesnod: i didnt include the mpg of the transition tank of fuel in the compar-o. so i accually rode a total of 1100 miles for this experiment. http://www.ehow.com/how_4911241_check-gas-mileage.html
one of the detonation (distortion) indicators when using lower octane fuel, is a drop in mpg. which is what happens to me every time i use 87 octane fuel. note: just because you dont hear engine ping doesnt mean it not happening. just means you cant hear it ping.
