I think we can run oils for much longer than 3K, or what the manufacturer calls for, but each engine is different. I would do a UOA to see how it holds up in the engine and then go from there.
Maybe. But it's not worth the risk IMO. Anything you gain by saving money by not changing the oil, you might be just throwing away in reduced fuel-economy in an engine pumping "gooey" sludge at start-up. Especially in cooler weather...
When I was changing oil, some buffoon pulled in with a ticking Windstar. He was pretty goofy and a bit smug when I asked him if he ever changed the oil in the 20,000 miles since he leased it and he said "no. how did you guess?"
It was obvious he was sort of trying to cover this up with an aftermarket filter and receipt of the only service the vehicle ever had in 20K+...
We changed the oil, pulled off the factory gray filter and then notated the engine ticked prior to change to CYA and boy was he angry since he had to turn the vehicle back in shortly to Ford as his lease ended. I told him we weren't liable if something were to happen to his engine --and that if something happened it was his problem...
