Well no technically not according to the ISO 4548-12 for particle test FRAMs best designed filter the Extended Guard or next the Tough Guard is 97-99% @ 20 microns. and that's ONLY on equivalent PN's PH8A, 3387A and 6607
The Mobil is 99.2% @20 percent efficiency rating (under SAE J1858 Multi-Pass Efficiency Test), across the board all PN's so splitting hairs i know but just saying..

daman1 maybe you should reread the Fram site info.
Tough Guard is is their top filtering filter (99%) and not Xtended Guard(97%) which traps less particles so it can be ran for 10,000 miles before replacing.
I use a lot of WIX filters because they are handy to purchase and are good filters but they are hard to trust sometimes.
On the 429 I was encouraged to go with the 2 qt version of WIX vs the standard 1 qt version.
After doing some crossing on the web I learned the 1 qt trapped 99% >20 microns BUT their 2 qt version only trapped 97%. WIX will make filters that cross over to other brands in a PHYSICAL sense but not MEDIA sense.
So far I have found no evidence that a $13 K&N oil filter will make an engine last any longer than a $6 Fram Tough Guard.:thumbsup:
People should use the filter they prefer however 99.9% have NO idea what brand of filter or who made it that is parked in their driveway.
