Luxury Coach Lifestyles - View Single Post - synthetic or regular oil on detroit series 60 engine question

I don't have a series 60 engine (just a mechanical 6V92T) but in doing a lot of research regarding oil since API is no longer certifying oil specifically for the V series, I found that one way of justifying synthetic is to do oil sampling annually and from the results decide when to change it. There are truckers out there (yep a different use pattern of the engine but not entirely irrelevant) that report going 100,000 miles between oil changes with synthetic oil, 15,000 mile filter changes, and a modern engine. I've seen reports of motorhomers using oil testing and changing still good oil after 3 years with annual filter changes. It seems the dino versus synthetic question requires broader perspective.
