Oil filter change vs oil change
Ford says for regular service 7500 miles oil and filter change. Severe service 5000 miles. The Jiffy Lube and other quick change places started the 3000 mile oil change myth. .....and it is a myth. Even antiquated oils of the 60s and 70s could go much farther without worry.
That said, I don't know if there's any benefit to changing an oil filter in the middle of an oil change or not. I imagine with modern oils and additive packages, and running a good filter, it probably won't make a difference, other than the extra money spent.
Do I know for sure? No. But that's my opinion.
