Good question Steve. I believe California tops out at 91 Octane also. There are different math formulas for determining octane ratings of fuel. The formula is on many of the pumps here. I think California's is an average of "Motor Octane and Reseach Octane". We have some sort of additive package that effects it to some degree.
