So yesterday while I was out cruisin around a little bit I notice that I only had a little over half a tank of petro. Pulled in to a near by Shell station and my money for gas. As normal I hit the far right light which is always 93, ten dollars in I realize that it is 91 non ethanoe and on top of that 4.5 a gallon. By now I'm like what the hell, it is a half and half mix 93/91 along with non/ ethanoe mix. I expected the Z to run a little better but boy it seem to run better that what I was expecting! What do you guys think? I am considering running a half and half mix for maybe two more tank to see if it continues to run this well. And before you ask, no they didnt have it in 93 non ethanoe. thanks D
