I used to sell those filters, brand name "Frantz". The ones I used were big truck units, replacements for the LuberFiner 750 that was pretty much standard equipment for all the big rigs in the 50's, 60's and 70's. The Frantz passenger car filters used a standard roll of Dale Earnhardt toilet paper (rough, tough, and won't take crap off anybody!), the cheaper the better! The filtration was capable of removing contaminants down to 2/10 micron diameter, 10 times finer than the standard full-flow filter will remove. The Frantz filter has to be used as a bypass unit, as it can't flow enough volume to supply the bearings' lubrication needs, but they really clean up the oil!
