I just performed my first oil change on this truck and I have to say nobody thought it out when making the engine. The new plastic oil plug comes out in a way that sprays oil all over then you move to the oil filter that is mounted vertically nice for the fact that it holds oil bad because there is a cavity above the filter so that sprays oil out when you twist it off getting it all over the oil pan. Now its time to fill it! The oil fill tube is near the fire wall and tilted towards the fire wall for added fun. I had to crawl on top of the engine to get to the fill tube so I didn't dump oil all over. Anyways the main point to this is anyone with this truck and engine some ideas for my next change is. Nitrile gloves for the drain plug. Use a punch to poke a hole in the bottom of the oil filter and let it drain before removing and find a funnel with a long flexible tube for adding the new oil. So far I love this truck lots of power and good mileage while towing 15 MPG towing 10,500 + lbs 18-19 MPG empty. DEF lasts about 5k and oil change was due at 7k.
