OK here's my situation, there is a gas shortage here on Long Island and even though I get to cut the line (police) there is NO 93 octane to be had. Sure I can reprogram my Evo back to stock and run lower octane gas but all that has ever been in my truck since she was 12 miles old is 93. I am considering putting E85 in for the very first time (IF I CAN FIND IT) and leaving my Evo on the #3 setting. Option 2 is running the lower octane gas and adding an octane booster. Suggestions?

 

Put it to level 2 and run 87 Oct. til your shortage is over.

 

That's what I was thinking, thanks.
