Today I did the first oil change on my 2011 2500. While it was fairly easy to do I was not expecting the massive rush of oil that came out once the drain plug was removed. I had the oil fill cap in the engine bay removed and sitting cockeyed in the hole. When the plug came out oil went all over my arm and hit me in the face, lol. . I had a little spill and some cleanup afterwards. I installed a Fumoto drain valve so I don't see this happening again. I couldn't find a 5/8 in dia hose clip to install on the valve to keep the latch from opening so I used a 5/8 dia rubber o ring which slipped right over the nipple part and fits just right into the pivot arm slot blocking it from opening. I'm all set up for the next change. .
