Ok, My M roadster is a 2nd car and I only drive it 6,000 miles per year. I take a lot of short trips which I hear is harder on the oil. If I am running synthetic, how often do you guys suggest I change the oil?
A. Every six months B. Every 6,000 miles (so once a year) C. According to the lights on the dash, irregardless of time D. Other ideas???
