I respectfully disagree with Jack. The paper elements are a function of the
quality of the manufacturer and should be as fine a paper as you would find
in a spin-on, full-flow filter.
Given that the paper is of adequate quality, the bypass filter will filter
a percentage of the oil and put it back in the pan cleaner than it was.
Eventually all the oil will go through the filter. Admittedly, it's not as
good as a full-flow filter but it's a lot better than nothing. Filters are
even more important with detergent oils especially because the contaminants
are held in suspension and won't settle out as with non-detergent oil.
If the bearings and pump are in good shape the pump will deliver more than
enough oil to feed the bearings and the filter, dumping some out the
pressure relief valve. If you have oil pressure problems, it's not because
of the filter but disconnecting it and plugging the holes is an effective
stop-gap to compensate for a worn engine.
