Our 93 over here must be REALLY bad, my mileage went down after switching to 93. Played with the canned 87 tow and my average was about 15-17 even with gunning it a little. When I started using the canned 93 it went to 13-16. I drove the same places and drove like there was an egg under my foot. I also couldnt even get within a second of my 0-60's while using 87. Just switched back to the 87 tow that I played with and gonna see how that goes. If it still doesnt improve then I'll know its the gas.
