Default Toilet paper style oil filter

What exactly is a "toilet paper style" oil filter?

They were a thing a long time ago when engines didn't have great or any filtration. I've only heard about them on engines from the 50s and back though. Think flathead Ford, etc.

I think it was called the Frantz filter. Something like that. If you're going to use one, be sure and put only Charmin toilet paper in there so your car doesnt get all irritated and fussy.

Those were a godsend for engines that didn't have an oil filter already.......back in the wooden-wheel days. Waste of time today. Adding unnecessary joints and seals in a pressurized oiling system is a setup for failure.

If space is a concern, you can just run a remote oil filter. There are tons of options that utilize spin-on filters.

What is the goal?

shortened service intervals? the canisters that used a roll of toilet paper for the filter element required 3000 mile oil changes
remote filtration?

the filters were designed for dipper oil systems (like a 1937 Chev stovebolt motor)

as stated above, run a remote filter. if you want better filtration, they make elements that are better that your typical COTS oil filters. many of the remote mount diesel filters will filter down to 2 microns

Toilet paper used to be popular on diesel engines.

A giant techonological leap backward into the nostalgic 1940- 1950's period of dealer or customer installed OPTIONAL oil filters, on rudimentary, cheap OEM cars and trucks, built and sold with NO FACTORY OIL FILTER. Yep, no ****. Brand new 1950 chevy had NO FACTORY FILTER. oil change intervals were typical at 1000 miles.
DIY would add a bypass oil filter, that ran a small fraction off the pressure feed oil galley- THROUGH a cellulose media filter, looked like a low grade roll of toilet paper, and the "Filtered" oil returned directly to the oil pan. Bearings were fed direct UNFILTERED oil from the oil pump. "The Good Old Days "

Adding such a throwback to a modern fuel injected, FULL FLOW FILTERed oiling system is idiotic
