Subject: Gas Grade Question

Could anyone tell me where to find information about the "AON" method Saab seems to use when talking about fuel grade requirements? A sticker in my car claims I need to use 93 AON, but in California it's (R+M)/2 everywhere, and one can only find 91 grade as premium fuel anyway. The question is - are AON and (R+M)/2 significantly different, and is the fact we are forced to use 91 grade here in CA negatively affecting performance and engine integrity of our Saabs? ...pablo
