93 octane fuel is difficult to come by here in Kansas. I discovered this today at a station across town. I'm aware that this is lower octane gas mixed with E85 to bump the octane, but is it safe for our cars? I don't run a tune, and have a track day coming up soon. Searches seem to indicate that my injectors won't keep up without a tune or LPFP. Would really appreciate some input on the safety, and potential benefit of trying this really cheap "93 octane" gas. I'm expecting some solid reasons why I should steer clear....
