270,000 plus miles. Dealer replaced the oil breather when new after I dumped oil twice on steep downgrades. Had replaced the lift pump as a precautionary move, then moved it to the fuel tank when my fuel level sending unit went out. Have replaced several track bars. Replaced the power steering pump. Still have original clutch. Replaced front brakes, but really didn't need to. Replaced the real seal between the transmission and the transfer case. Recently replaced the rear differential seal. That is about it. I get a tad under 20 miles per gallon today as I did when it was new. It is rough riding and noisy, but you come to expect the feel and drive. The 6 speed has always had feedback if you are turning where my 1996 5 speed did not. I do my best to shift going straight for smoother shifts. I bought the 2001 as the 1996 was too long with the extended cab and 8 foot bed, otherwise I would probably still be driving it. It is about six times nicer to adjust the valves at 150K vs 25K.
Much of my driving includes dusty ranch roads. I change my oil every 3,000 miles and the filter at 6,000. I use Delo 15w-40 oil from wallyworld and filters from Geno's garage. This has been a pretty good truck, but I still use a 1972 Chev K20 as a ranch work truck and a 1973 Jeep CJ5. All have original engines and transmissions and are still going strong. Although they work in a harsh environment, I try to keep the mechanical stuff clean.
