Hey Guys,
I just found this "Oil Filter Study of 31 Filters" that were tested in Jan. 2011 on a site called GM Truck Central. Click here for the "Study"... 2011 FILTER STUDY
Has anyone here ever heard of this study?
Is it a valid study to compare filters?
I'm surprised Royal Purple looks to be the best, then the Amsoil EAO filter.
I found it here OffShore Forum when researching old AMSOIL EAO Filter numbers that were once rated at 15 microns. Amsoil's new filters are now rated at 20 microns, but I don't know if they've also changed the test criteria. I think I heard that the old EAO filters were better.
By the way, is there a way to subscribe to different threads on this forum and be automatically notified by e-mail when a new post gets posted like other forums?
Regards,
Chris
