'04 DR non-HO, 328,000miles. 3K for 1st 100,000 (service contract), 5K between since I've been doing them. $14.00 Walmart, Mopar filter and Chevron Delo-400 its whole life. I have used a couple different Wix filters from time to time and it currently has a K&N for the first time. It was a gift and I didn't have a Mopar filter. Fuel filter every other oil change. Trans. and diff. every 30,000. I've burnt the paint from the diff cover a couple times. Mopar diff oil is like $18.00 a quart. 4 quarts. The reusable gaskets are really good! I'm now on my second, billet, trans. input shaft after it was upgraded in 2010. Two water pumps, an injector, two APP sensors and a belt tensioner is all I've ever done to keep the engine running.
