Reason I asked is I’ve been getting the wix xp’s at oreilly’s.Mobil1 is pretty much just a cheap purolator with a Mobil1 paintjob, the Wix XP is a better built filter but pretty poor in the efficiency standpoint. Of the premium synthetic media filters these days, about the only good ones left are Royal Purple and Amsoil, Royal Purple are usually the cheaper maybe a hair more expensive than a Wix XP but much better efficiency with excellent build quality
I can also get Purolator boss would that be better then the wix xp and the Mobil 1?
Cool I’ll just buy a boss for my next oil change
Yep they both went cheap on us but they didn't lower their price did they?XP has fairly poor efficiency (50% @ 30 microns), M1 is somewhat better, 99% @ 30 microns.
I think we just covered this on the XP… it’s like 99%@35 microns, the 50% is @ 20u IIRC. The XP is a well-built filter and will likely serve any engine well, but it’s not designed nor intended to provide the finest filtration.XP has fairly poor efficiency (50% @ 30 microns), M1 is somewhat better, 99% @ 30 microns.
Plotted UOA PC data pretty much correlates with the filter ISO 4548-12 rating. With all factors held constant, higher efficiency filters result in better filtration and cleaner oil. No accurateky conducted lab or real world case will prove otherwise.If you want to know how well the filter works, you'll need to UOA with particles for your engine and driving style, and worry less about marketing info and bench tests.
The Boss filter is built like a brick outhouse. Its synthetic filter media has a similar synth "backing" screen fused to it, providing rigidity and extreme toughness. It will not tear whatsoever. Its filtering ability is on-par with or better than a Wix XP.Is purolator boss having any tear issue ? Or any common issue ?
