The oil might last forever, but there is no telling about the man-,made additives in there. Those chemicals might deteriorate over time. How much time? I doubt if anybody really knows, it is just guess-work.
Come to think of it, when (if) oil "breaks down", what does it become? Once those long-chain molecules are broken, they are not "oil" anymore. What is it?
I buy my own Chevron Delo 400 oil at Costco (about $13/gallon in a 3 pack), and a NAPA Gold (Wix) filter, then take it to Masterlube. They charge less than $30 to do the oil and filter change and check all the fluid levels. It is worth it to me to not have to crawl around under the truck, then have the dirty oil to handle.
