How does my truck determine my oil life?
I drive less than 10,000 miles per year. And my truck takes a full year to tell me I need an oil change. Now I do use high mileage full synthetic, so it's probably fine to go that far. But I do feel like it "feels" a little smoother after an oil change.
So I do less than 10k but I certainly do more than 3k. I just looked at some old paperwork and it looks like I've been doing roughly 6k per year. Is it just milage based? Or somehow RPM based? Or does it somehow 'sense' the qualities of the oil and it just knows when they've gotten too bad?
