The Frantz is the only one of the TP filters that had a design that made it impossible to have any significant tissue migration into the oil. There were two screens covering a 1/16th orifice. This didn't stop the BS stories that have always come with TP filters. If anything should get past the two screens and thru the 1/16th orifice it still has to go thru the oil pump pick up screen, the oil pump and the full flow filter.
When I change my filters the paper is very strong and can be torn at each sheet. Oil makes paper very strong. As a rule a neglected roll of TP will be hard. If you try to unroll it it will fall apart. The paper won't get into the oil but the oil will get dirty and thick and won't circilate. A grease monkey will see the Frantz and say there is your problem. You got TP in your oil.
The insurance companies don't pay for engine damage claimed to be caused by TP getting in the oil. They might send an engineer to see what happened to the engine. It is almost unheard of for the insurance company to get a claim. One time the insurance company wanted to know why there were larger pieces of paper in the engine than the orifice at the outlet. It's called trying to scam the insurance company. They will make a grease monkey crawfish in a hurry.
The stories usually start with someone said, someone heard about a guy. That sort of thing. One guy told me he knows a guy that got TP in his catalytic converter and it burned the valves. An Amsoil dealer here in town told me he opened up his Frantz to change the element and the housing was empty. A whole roll of TP was in the oil system. He might be just a liar but I suspect he forgot to put a new roll of TP in after he pulled out the element the last time. He hasn't had any problems since he replaced the Frantz with an Amsoil bypass
Not to pick on Amsoil dealers. Some of my customers are Amsoil dealers. I don't remember ever using a Frantz for coolant. I would think they would work as good as the Motor Guard or Gulf Coast. The paper holds together good. I have used the Gulf Coast 0-1 jr for a drinking water filter. I learned not to leave a roll of TP in my camper water system without using it. The paper will sour.
The Gulf Coast 0-1 jr is a lot more corrosion resistant than the Frantz. The jr is plastic. The Motor Guard is die cast aluminum with an epoxy coating. I took the Motor Guard coolant filter off my Ford diesel truck and put it on my Legacy motor oil. I took the 0-2 off the truck and put it on a chiller at work. I bought the old truck needing a ring job. It won't be driven until I overhaul the engine. It's a 6.9. It takes 2 gallons of oil to get from Dallas to Seattle and back.
