Did you try AutoZone for the oil? Here in Colorado Springs the AutoZone a mile from my home has Mobil One 0-W40 for 6 bucks a quart. You can save some major cash by doing your own oil change. It's not hard. Search the forum for the service manual and you will see. Andrew (I think) has even posted a simple checklist for changing the oil somewhere in here. The oil filter is on top of the engine so that's easy, too. I would suggest buying the filter from the dealer and keeping the receipt for it in case of any powertrain warranty issues down the road.
