: Just thought I'd kill some time with these observances:
: 1996-M3 Luxo Coupe
: 19k miles
: -car drank about a quart every week
: -problem, leaky valve cover gasket (leaks from rear of valve)
: 23k miles
: -changed oil to Castrol 5w-50
: -average oil consumption of one quart every 2 weeks
: 26k miles
: -changed oil to Mobil 1/15w-50 and filter
: -ran Laguna Seca all day at redline, no oil use
: -drove the length of the USA and back (CA to SC to FL to CA), 7k miles, drank 1 quart of oil the entire trip
: 33k miles
: -changed oil to Mobil 1/5w-30 and filter
: -no oil consumption at all in last 1.5k miles
: I don't know, but running the lighter weight oil has dramatically changed oil consumption and the general smoothness of the car.
: I reread BOB//M3's advice on Amsoil 0w-30. Seems good from a lubrication/protection point of view. How's the oil consumption on your end Bob?
: I state these things as some M3 owners have cars that drink a quart anywhere from 1.5 to 2.5k between oil changes. And some of you guys have no issues whatsoever.
: Seems my car loves the factory rec. 5w-30.
