Is this oil fine for the 6.7? I can get it at NAPA for a good price. I can also get the oil filter at NAPA, but do you guys recommend NAPA filters? Thanks

Also, I bought this truck at my dealer with 22k miles. The previous owner always got the oil changed at the dealer, but I want to do it myself. The dealer said I could change it myself and still be fine on the warranty, but is he just blowing smoke or is that right? Where should I keep a log of the oil changes?
