My 850 recommends 91 also.

I live in Denver and have heard that altitude also affects octane lowering the requirement. I run 85 and 87 depending on how I feel at the pump. I don't notice any difference performance or mileage wise. Two dealer mechanics advised me to run at least 87 if not 91. They said mileage would increase.

Who knows?

Try several tanks of each and see how your car runs.
