Kuato, I didn't change the oil - just the filter. I might have another one to cut open when I do the oil change in two weeks. There will be 1200 total miles on the engine then.
I bought a new truck on Dec. 31 and it had such poor build quality that I returned it a month later and replaced it with this truck. The build quality was better but still not what it should be. Also, the dealership falsified the PDI paperwork by falsely stating that they checked things that were never checked (washer fluid pump not hooked up from the factory and PDI sheets claims to have verified washer/wiper function was the icing). The differential was low on both of these trucks by about 16 ounces. I haven't checked out the transmission but being a manual gearbox I don't feel that it would make any difference to change the gear oil early. Transmissions tend to shed metals until worn in so I'll let it go, along with the rear axle, to 50,000 miles.

OFF topic but I saw a video within the last year by i think a lawyer for consumer reports magazine saying that many CPO (cert pre owned) inspections were also essentially not through, and the ONLY hing you got with CPO was a slightly different warranty
