But everyone here ignores the filter package that says the filter is good for 20,000 miles. Personally all for clean oil but start with change oil often and a high efficiency air filter and change oil filter with the oil change.

Read down to the end of this article.
Yep, and it says: "
Any dirt that gets past the air filter enters the engine, becoming the enemy of all lubricated components. This makes the oil filter's job more challenging."
So does that equate to using a low efficiency oil filter to better achieve the role of being the oil cleaning component when contamination does happen to get into the oil?
I am glad you asked Zee...

As nothing is black and white there is some give and take in everything.

Oil filter design is somewhat of a balancing act between particulate size, filter medium, surface area of filter medium and oil pressure. The finer the filter medium, the shorter a filter's lifespan before it begins to show pressure drop and the oil filter bypass valve is opened.
One point on the above link is cake filtering, by which the filter loads up. After a point the particles become desorbed in the filter and the gains in filter loading fall off. While direct filter pass is important, I believe there is more to the picture. The Ultra has a bypass PSI of 12, and some believe that bypass events do not happen. I do. The number of pleats in the filter become important to for filter loading. (IMO)
That article doesn't even address the performance differences between media types, which is a lot. They say: "
The finer the filter medium, the shorter a filter's lifespan before it begins to show pressure drop and the oil filter bypass valve is opened." That might be true about cellulose media, but not for full synthetic media which has much more holding capacity and doesn't load up as fast. That's why most full synthetic media oil filters are rated for much longer use than cellulose media filters. The differences between cellulose and full synthetic media oil filters has been hashed for 10+ years around here.
The chances of a full synthetic filter going into bypass under the same loading of debris is much lower than with a cellulose filter. I don't think anyone here believes "
bypass events do not happen." I've never seen anybody say that.
And the number of pleats in an oil filter is only useful if comparing two filters of the same brand and exact same media to compare media area. All filter media is by far not created equal, so trying to compare a cellulose filter to a full synthetic filter by pleat number is completely useless.
