I decided to changed my oil today myself. My local dealer wanted $200 for just the oil change no fuel filters. So I have 5200 miles on it and figured it was time for the first change. I picked up a filter from the dealer for $10 and got 10 qts of shell rotella semi synthetic 10w 30 for $45 from auto zone. Overall everything went smooth. The front bolts on the pro4x front skid plate were a little hard to get out but overall the job was easy. I'm glad I changed the oil it looked pretty dirty it was dark black but that might be normal for a diesel. This was my first oil change on a diesal.
