Unsure if that hat is actually a problem or if the computer is seeing it lean because it’s expecting regular gasoline to be used.
any thoughts on this would be great!
I don't understand what was going on because our engine requires high test being we in Florida have 93 ,and this is what i am using with the 3 gal of E 85,,, you used 91 octane and got a eng light doesn't make sense,,,,. just driving around easy maybe try 1 gal,,,, then try 2 ga,,,,l then back to 3 gal ! by adding the extra 91 , did you feel any change with power??
