While we are on the subject, something you may or may not know. Looking at a filter substitution guide, which I have done several times so as to reduce the types of filters necessary to service my equipment, I obviously look for the smallest micron filtration number.
What you have to remember is that "full flow" rated filters have a limit as to how small a particle they will allow to pass, usually 20 microns, give or take to allow the volume of oil to pass that the engine requires.
On OTR diesels, you will find 2 filters, a full flow and a partial flow. The partial flow only gets about 10% of the oil volume (due to internal restrictions) but it's of a much tighter media limiting flow-through to around 5 microns and is in there to clean up the leftovers......one of the reasons why you get a million miles between major overhauls.
Course you could do it all with one filter but to get the full flow, it would be huge.
