What does it take to make 20k mile oil?
One of my fravorite You Tuber's, Jason Fenske, at Engineering Explained gives us an inside look at what kind of R&D it takes to make a 20k mile oil. Notice the 500k test miles they put on the Silverad...

its been 30 years ago now, but in our trucks (cummins and cat motors) we always had a 20,000 mile oil change interval. we used delo 400, and the oil didnt really seem too bad at that mileage.
most of the trucks needed about a gallon added at 15,000 to make it to 20,000 but the detriot motors needed a gallon added every week.
at an average of 2300 miles per week, it didnt take long to need another oil change.
I still use delo 400, but its not the same oil formulation today as it was back then..
