I own a 94 318i, and my question is that everytime I buy a new oil filter from the auto store, the one they give me doesn't fit my car. I always have to ask for the 97 filter because that one apprently fits my car properly. The one they give me is the short fat filter which they say is suppose to be for my car. The one that fits is the taller and skinnier filter. Which one is correct? and, do you think the previous owners of my car did something to the engine? Also, ive noticed that my 4 banger runs like a 6 cylinder. At speeds of 80-85mph, the rpm is only on 2 1/2. shoudlnt that be atleast over 3 1/2+?
