I have a 2001 duramax LB7 with 285k. P.O. put 200k on it before me. His father in law was the owner but passed away. He used it to haul recycled cardboard bales, pulling an 18ft bumper pull with two bails and one in the bed. Son in law said his FIL always changed the oil (diesel specific but no particular brand) every 3k miles and used Wix filters. I had several K&N filters from my previous duramax so I use them. I am sure the engine will outlast me as I don't daily drive the truck, just for hauling.
