My husband just bought me a 2000 528i for my birthday so I could have a car with my initials on the hood. (he doesn't mind driving it either). He usually changes the oil and filter in our vehicles. However, he cannot find a service manual (Haynes has them for other models, but not the E39). Does anyone have tips on changing the oil and filter, or know of a service manual? Thanks in advance for your help. B.M.W.
