I did my 1st oil change last night at 3,000 miles. I know people have different opinions on this topic. I like to do the filter change from above. i remove the tube from the turbo to air-box (takes about 2 minutes). This gives easy access. I was so happy the stock filter was pretty easy to get off with a common oil filter pliers. I let is cool down a while and didn't spill a drop taking off the filter. Draining the engine was easy. I was done in less than an hour. Most of the time was letting it drain. I used Mobil 1 diesel oil and a factory mopar filter. i remember some real nightmares with removing the factory filter on past new trucks and was real happy it was uneventful.
