Pennzoil and SRT filter. Mobil 1 is always good too! Do it yourself and know it's done right. I work at a Chevy dealership and even though we have great employees...I would NEVER let the 10.00 an hour oil tech near my car. If you always knew a real mechanic was doing the work then OK. But no dealership does that anymore unless maybe a very small dealership. Most larger dealership have a stand-alone oil change area and use low pay guys to do the work. They don't make a lot of money doing oil changes anymore.
