I recently had my first check up and was informed that the dealer will only change the oil and not the filter. I would definitely reccommend that you guys pay for the filter if you have to. There could be small metal pieces from engine during break-in and I believe they need to be removed. I actually broke my vehicle in for the first 1000 miles under 55 miles per hour and alternated the rpms when driving. I had my first check up at 3000 miles and have them change oil and filter. I plan to follow a 3 month 3000 mile interval for oil changes. I will make sure to do the 7500 real axle fluid which everyone says is so importment to keep up with also. I was shocked to find out about no oil filter on first check up
I'm going to stick with the recommended 7500 first oil change. Today's vehicles are better engineered than they were just a few years ago. For an example, the new GM Trailblazer, Envoy, and Bravada's first recommended oil change is 15,000 miles.
