Exactly, the AZ 91 is somehow extra crappier than normal 91. So I've been mixing 3 gal per tank of E85 to get me just over 93 octane.
The car LOVES the mix, other than the fuel pump that it. You can definitely feel crisper throttle response with the blend. If we had 93 here I'd just run that, but no such luck in the SW.
