This is good info now that i'm out of the maintenance plan. And since it's now on my dime, how often should I change my oil if I do low mileage (6500/yr) - BMW seems to have a separate list item for low mileage oil changes and for whatever reason, the last time was only after 6 months even though mileage was going at the same rate. Would I want to go past once a year with their synthetic? Should I do it per mileage or time?
