I just got mine this past Thursday. Mine now has 200,000 miles on it. It still runs great. I had to replace my fuel filter tonite and I suggest you do the same. I could actually tell a big difference in the engine after the fuel filter change. I think the original filter was still on the truck. Most important, listen to the guys on this forum when they give advice.... Especially when 2 or more folks suggest the same thing. Welcome to the club, I'm new too.
