But do the arithmetic. Make it simple. Assume $10 in price savings and a 10K change interval. That means saving a whole 1/10 of a penny per mile! If you can't afford another dollar every thousand miles, then you can't afford an E46, a BMW, or any car, for that matter.

Boggles my mind how some people seem incapable of looking for "BMW LL-01" on the back of a bottle.
