How do you find out micron rating for filters? Ive been using a STP filter.I use Amsoil EO080 foil ilters on my 6.7. The micron rating is 15 for the amsoil and the fleetguard LF3972 is rated at 30 microns. Big difference is filtering. Good stuff aint cheap and cheap stuff aint good.

Most oil filters can filter down to a low micron but the efficency will be very low. The mopars highest efficency micron rating i beleive is 30.What is the micron rating for the standard Mopar Oil filter (MO-285 part number 05083285AA)? I had a parts person tell me it filters down to 9 microns which is great if it's true - especially since it's quite a bit cheaper than some expensive ones that only filter down to 15.
