Octane and Gas Mileage (archive)

I have a 95 525i auto. My question to the group is what octane are you using and what mileage are you getting with the M50 (OEM chip)? I have been running hi test (93) and get around 24-27 mpg average (mostly hiway). The problem is the price of hi test here in CT is $1.60/gal and up!!!
Anyone run regular (87)? Any problems?
