I was thinking of driving my car down to the states for some mods and tuning later on in the year and was wonder if 91 octane was available at most gas stations or if it is mainly 93 octane in the mid-west US? I'd like to keep strictly 91 octane in my tank for the tune since that's all I can get in my area of Canada. The states I'd be driving through are MI, OH, IL, IN, WI, and MN. Can you get 91 readily in these states or is it strictly 93? Thanks.

 

Um I think we have some 91 around here in columbus ohio. I mainly put 94 oct in my evo so i'm not too sure. Go to any sunoco. I think they have 92octane also.

 

MN has 91, so does WI.

 

most any where in ohio you can get 91 at almost every gas station
