Hummer of Thousand Oaks, as stated before, provides the 1st oil change for free. But I am thinking of changing it soon myself and putting synthetic in. Any avid synthetic users out there. When should I start using it, immediately or wait for the first oil change to allow proper break-in.? I only have about 600 miles so far. Also, who has the GM number for the Oil filter?
