The dealer said they did an oil change on it, and I can see the new fram oil filter but the oil itself looks dirty, compared to conventional say 5w30 or 10w30 then I thought that maybe it uses some sort of other oil that is just darker to start with. Also how do you then reset the change oil and change fuel filter message. Thanks again. So far I am loving my first diesel truck, it is a big step up from my 2000 gmc sierra 2wd with 4.8 v-8 that I had before. The power and torque you feel from this truck is insane. I will post a picture of my new truck in the next day or so. Also does anybody know the average life expectancy of a duramax motor?

It is a little more involved that that. Did you not get any manuals with your truck? I can e-mail you the diesel supplement that you should have gotten with your truck. But, to answer some of your questions..you need to unplug the WIF sensor on the bottom of the filter. If you get your filter a little loose, you can drain the fuel out of it, but it shouldn't start pouring out. The dirty oil that you have is normal...EGR doesn't help this since soot and such gets kept in the engine. In some trucks it takes longer than others to turn the oil black. It also depends on how long the dealership lets it drain. Anyway, let me know if you want the diesel supplement e-mailed to you...just pm me your e-mail address.
