Fram Tough Guard. $4.50 at Wally world
Rated at 98.6% efficient at the 20 micron size according to the ISO 16889 test method (multi- pass efficiency). A higher efficiency rating than the Mobil 1 (96%) or the K & N filter at more than 3 to 6 times the cost
BTW, someone did just what you said Mike and cut a whole bunch of filters apart and commented on the apparent quality of each. Don’t have the link, but IIRC he liked the Tough Guard. Not to be confused with the budget Fram Extra Guard at half the price, which the guy didn’t like.
This study

is a little better in that they also compare the filtering capability of each filter, where as the other guy did not.
A $4.50 filter and 5 quarts of Shell dino oil from Costco at a buck a quart. That much more left for Jim….
Hey. If you guys really have a personal relationship with your vehicles, why not use these filters?

Isn't your car worth a $100 oil filter?
