My local dealership is a bunch of morons. They can't even tell me the type/weight of the oil when I give them the part #'s when they look it up in their system. But they're quick on the price - $19 A QT
This is my second(and last dealer completed) oil change under Chevy care, so I'm going to press for it to be free or seriously reduce the per qt price.
