there is no 93 octane in sioux falls
there is 91 octane bp gas and 92 octane shell 10% ethanol added gas.
i have been using e85 blend.
10 gallons of bp 91 octane gas and 2 gallons of e85, yields 93.2 octane and 14% ethanol content.
datalogged my car and saw no timing corrections. confirmed with cobb tuning and they said that it is fine using it this way.
