Preventative maintenance when changing oil (BMW 7 Series E32)

Preventive maintenance with engine oil change is performed on cars with gasoline engines every 15 thousand km or at least once a year. For cars with diesel engines, oil change is performed every 10 thousand km or once a year. Under difficult operating conditions, such as frequent short-distance trips, city driving, frequent driving on mountain roads, towing a trailer and operation in dusty areas, the frequency of maintenance should be halved.
