Oil life?? Time vs. mileage ....
I think the big thing is moisture and combustion contaminants. If you could afford to pay for periodic analysis, you could probably prolong it. But it's undoubtedly cheaper just to change it.
Because I drive so little anymore, I think nothing of letting my oil go 2 years at a time, but no longer than that. My 95 Olds, which belonged to my Mom, still to this day only has less than 50K. That's right......50K. Before my legs got so damn bad, I rode by trike all over hell in this town. I may put "More battery" in it and ride it some more, LOL
