I DARE SAY THIS - a decent-sized Fram ultra (maybe even the little thimble sized ones)
WILL last 50,000 miles with regular oil changes on modern (non-sludging) engines.
Modern engines just don't load up oil filters with debris like they used to 30+ years ago.
on vehicles like my F150 with a 4.6, it has almost 180,000 miles and the top of the head looking inside of the valve cover has ZERO sludge or(even varnish) inside of it.
On a clean engine like that, a Fram Ultra XG-2 would last 50,000 miles easily with regular oil changes.
