Consider the truck that was being referenced gets about 50,000 miles a year. With that said, I think it means it hardly ever cools off and there's very few short trips. Do you think that has anything to do with it? I'd say the ill-informed opinions of the OLM may not have as much to do with the long life, but instead that the engine sees fewer cold startups.
