+1. The computer and Ultimate Service call for an oil change every 15K (and an ADDITIONAL change after one year if you hit that milestone before your mileage milestone), but Mike Miller's Old School BMW Maintenance Schedule calls for a 7500-mile interval. I think 5K is too often since that's a common non-synthetic change interval, and synthetic oil can legitimately be used longer -- plus using 7500 means you just pay for every other change while under Ultimate Service and ask the techs not to reset the computer.
