Hi,
I need to add oil to my 1987 325is (about 119K miles).
What weight should I use. (I'm in SF -- moderate climate).

Thanks

15w50, 20w50, 10w40. I'd personally go for a 50 weight.

20w50. If you have any leaks the weight is so heavy your car stops leaking almost completely. Dont go for the 15w30 unless your cars in top shape beucase your just gona piss right through that stuff if your engine leaks.

Mobil 1 15w/50 Full Synthetic is the best CA oil that i have found for german cars yet...hands down the best

synthetic is good, but just like antiburn said, it will leak if u have a slight crack.
