I did test dino Rotella oil after 10,000 miles, on heavy working F450 and Blackstone gave it clean bill of health.
I switched to synthetic for extra protection. That paid back as on our diesel sedan - oil pump chain broke and the engine work few minutes with no oil pressure.
I prize synthetic oil for the protection and replacing head gasket some time later, could confirm that cylinder walls are in perfect shape.
