I may be helping my daughter change the oil and filter on her 2004 Mini Cooper this weekend. Any suggestions on what oil filter to use and where to get it? Mann seems to be the one that keeps coming up in my research. It is the cartridge type. Also if anyone knows, what is needed to remove the cartridge housing. It looks like a $40.00 36 mm 3/8" drive socket is needed. Is there enough room for a 15" adjustable wrench? I'm not looking to expand my tool collection at this time unless I really need to.
