My BMW’s owners manual calls for 15w40 for normal ambient temp operation. It calls for 5w30 for cold temps.
From the documentation I have, it has been living on 5w30 for its whole life (10 years).
The closest oil I can find locally that carries the required API-SH rating is 10w40. I don’t doubt that this will be sufficient.
However, my typical daily commute is 3 miles each way from the bus stop. The car barely gets warmed up by the time I have arrived.
Should be sticking 5w30 since the car barely gets up to temp?
Any advice is appreciated.
