But you missed the point.
Will OEM filters let the engine last to 300,000 miles, sure.
Will a filter that cost $2 less than OEM let the engine last 300,000 miles, sure.
But over those 300,000 miles, that $2 per filter adds up.
Is the engine better with one filter or another, no idea, only a complete teardown would let you know (and even then there are too many variables to really compare).
You asked why not buy OEM, and I gave a valid reason. You don't have to like or even understand it.
Not sure what drinking water has to do with oil filters.
Wait, are we talking about filters cheaper than OEM filters or more expensive than OEM filters?
You seem to be jumping between both in your posts.
I am in the camp that you really gain nothing using a more expensive "high end" filter vs OEM filter (or other inexpensive aftermarket options) if doing basic oil change intervals.
Many do it just to feel better, and think more expensive is better.
Are there benefits, maybe, but none that I think most will notice long term.
