What kind of gas should I put in my 97 850 glt? The dealer says nothing less than 89.
Is 92 necessary or ideal?

There is a discernable difference in power when I burn premium (92) fuel vs mid-grade in my 850 R. I'm assuming that the better fuel allows higher boost without detonation. That said, I usually run mid-grade just to save a few bucks.

I think the manual says you can run just regular (87). I guess it would be okay in a pinch but I, too, choose to run mid-grade gas (89) vs. premium (92)to save a few bucks. Or you could alternate fuel types, if you like.
