yea. I think thats why it says 91 b/c thats all we can get. Anyone know why this is?

 

I can't seem to find anything higher than 91 in Arizona...

 

Why risk it...you bought an Audi so you knew what you were getting into...love having 94 up here in MI...makes you feel even better...

 

Yeah I use sunoco ultra 94...

however, yesterday I filled up on 91... thanks to a phone call from a friend letting me know that a local shell station was all sold out of regular, and selling premium at regular's price... so 91 for the price of 87... not bad! (they didnt have a middle grade... old school!)

 

in cali we can only get 91 because the higer octane stuff just wouldn't sell enough here. very few 76 stations (and a few sunoco, although they aren't in cali) sell 100 octane. it costs close to 5 bucks a gallon at the san jose 76
