In Reply to: SIL or mileage oil change. posted by moots on February 22, 2000 at 07:01:49:
E36 325is 7k miles per year. SIL last 15 months. Lots of short journeys in traffic. Carry out an additional oil change between SIL at around 3.5k miles.
E34 520iA 22k miles per year. SIL last 4 months. Motorway cruising. Oil changes as per SIL.
I think it depends on what type of miles your car does. Short trips in traffic probably punish the oil more than motorway cruising.
