My previous '05 Hemi powered 2500HD at 120k miles when I traded it still used it's usual .5 qt of oil between 5k mile OCIs. Still ran as strong and quiet as it did new. Odd, 4200 rpm is also twice what I'm turning at 2100 rpm! Gotta love math! My '03 Cummins Ram turned 2900rpm on the same uphills the Hemi turned 4200rpm. Neither suffered any ill effects from it.
300 hours at peak hp rpm full load is a good indication of an engine's ability to handle work no matter the engine or how you want to downplay it. How did you arrive at 18000 miles at 60 mph? If running in O/D, that would be 140+mph non stop for 42000 miles. But the engine was in the lab.
