To be honest, the last oil (and filter) change on my 2002 Explorer (daily driver) was more than 100000 miles ago or about 9 years now.
Of course it needs some refill from time to time, so i guess not much (if any) of the original oil is still in there.
Still runs just fine - it's astounding.
Am I stupid?
No - it's an experiment.
