Don't lump all bypass filters together. Some don't clean oil very well and use elements that cost more than an oil change. I have a Motor Guard bypass filter that cost me less than 30.00 in 1971. It paid for itself in the first year. It has saved me many thousands of dollars in 30 years of use.
The Motor Guard is the only one that does everything I want it to do. The best three bypass filters I know of are the Frantz, Motor Guard, and Gulf Coast. Most of the Gulf Coast filters go to the Department of Defense. Motor Guard is best known as a 0.01 micron average compressed air filter. The name Motor Guard didn't come from air filters. There is nothing more important than clean motor oil, ATF and fuel.
No telling how many times I've heard the remark "I can buy a lot of oil for what a bypass filter cost".
These companies have all gone to special elements they sell. After 40 years of using toilet paper I will stick with good old Scott Kimberly Clark. One filter company claims to use cellulose in their filters. Toilet paper is 100% cellulose. The trick to keeping oil clean is more cellulose in a housing and less air.
I saw a dual remote setup in a Napa store the other day. That company made a good filter at one time. The elements were too expensive. They shouldn't have cut it open so I could see it. It was like a cheap hamburger("where's the beef")
. Nothing much inside. I expected to see it packed with filter media. They said you could go farther between filter changes I said yes and get a higher wear rate.
