Was at Bimmerfest in Baltimore a month or so ago and to my great surprise BMWparts Source.com sells OEM synthetic mtor oil for $6.50/qt!! I don't know about in your area for me this is a steal!! They were great bunch there and i walked away with enough oil and filters for my next 2 changes for just under $106.00. Not bad I pay well over $8.00 for Mobil 1 or the equivelent. Check these guys out well worth your time and effort.
