A big rig diesel, revs around 2000rpm, burns oil as a fuel, and is built more robust than a mass produced car engine.Sore loser? Who told us way back when to change oil every 3000 miles. No NOT the car manufacturers but the BIG OIL COMPANIES. Its like shampoo manufacturers directions. Lather rinse and repeat..motors, 's how they sell more shampoo. In the Company owned diesel semis I worked for it was no big deal to go 35,000 miles on changes and often more. We would put 2 million miles on those motors and VERY seldom had a problem unless some nu-be ran it low on oil. Oil technology has come a very long way since WWII. So have the oil filter mediums, the engineering of internal combustion motors, the specs for manufacturing parts etc. I read an owners manual decades back for a 1911 LaSalle. It said to change oil every 30 days or 800miles. Should we go back to that standard?
