First Oil Change. I used 7Qt of Valvoline Max Life and a Mopar MO899 filter. Man that filter is huge.
2 things:
1) I used max life synth blend 5w-20 for this change because much of what I read said that the first change should not be full synthetic and max-life met ms-6395 spec. At 10k, I will go full synthetic (probably Royal Purple)
2) MO899 is HUGE. When I purchased it, I purchased a cap wrench to install it. it wasn't until I attempted to remove the factory-installed filter (using that cap wrench) that I noticed the difference. i thought I had bought the wrong filter. Once I had the old off, I checked the mating surface and discovered them to be the same, so I installed the 899. after installing, it looked like the new filter was making contact with the guard and motor, to I removed it and check for scratching. I found none, so I re-installed and then ran a shop paper towel around between the rim of the filter and the surrounding "stuff". It moved freely, giving me the confidence that the filter is proper for that truck. After completing the change, I checked and double checked the bottom of the D for leaks. I could not find any. Still, I cannot help having a tinge of fear that I am going to have issues.... (probably paranoia).
A couple oil-change tips:
1) Remove the cover that has the access hole cut out. It really was not that big a deal to do and made a WORLD of difference. Not having to try to work through the access cover hole was of significant benefit (definitely worth the extra few minutes).
2) Assume your drain bolt will be problematic (difficult to remove) and get/use your "aid". For me, a boxed-end wrench that is just large enough to fit over the handle of my socket wrench was perfect to get me more leverage.
3) Because my D was on the ramps, I elevated my drip pan so that the oil would have less of a chance to "splash".
4) Many people the mess made by removing the filter. I was prepared for this and simply kept the filter in place allowing the oil to hit that, then drop down on the channel and run off into the drip pan. First spun the filter loose so it leaked. When that stopped, I removed the filter (from the threads and simply held it there until it stopped pouring oil from the channel. Once that was done, I lowered the filter to the drip pain and allowed the rest of the oil to simply "run off".
