Ive seen all over these threads to never use a gasoline with an octane rating lower than 89...they all say to use 91. But is there an octane too high? I had to fill up the other day and the only gas station i found with octane over 89 had 93. So I had to fill up with that. Is this gonna cause problems or am i allright? Since then the idle seems to have gotten worse. Shakes more.
Input anyone??
