According to the statistics from the 'combined efficiency and capacity' test (SAE HS806):
The top tier filters(combined cellulose and synthetic fiber filtering media)are in order: Amsoil,Mobil One,and Hard Driver.
Main tier filters(mainly cellulose media with mesh support needed) are in order:
Hastings,Wix,Pure One, Purolator, AC,Defense,Group 7,Fram,Napa Gold, and Pro Tec
There are probably other filters not included in this test which would be sprinkled in here from top to bottom.
