Nobody "forces" the efficiency thing on anyone ... where are you coming up with that nonsense? You think saying that official controlled test studies show that more efficient oil filter reduce engine wear is "forcing" it on people? - wow It's just technical information to educate people about engine wear wrt oil cleanness - the info is out there if people are willing to self study.
But you seem to really use this Spec Sheet mantra as a way to discount other's efficiency claims, on brand in particular for whatever reason. But what's funny about it is the Purolator/M+H Spec Sheets show pretty bad efficiency on some filter model, so I guess that's a good thing for people who want to use a more efficient filter.
