Just look in the manual for the octane requirements and use that. No sense in wasting money if you dont have to..
My BMW usually gets 19-24MPG highway on a light foot with 92 (big sticker for premium fuel on gauge). I saw it go down to 16-20MPG using 87.
I'd do a little research of what the oil change interval is for the car and see what the forums say to do. A lot of the newer cars are specifying 10K+ miles. Not sure I'd be following those. Certainly not on a newer BMW.
