Our efficiency is a little higher, the ability to trap and hold dirt exceeds the amsoil filter by 3 grams, we use a stainless steel screen to support the filter media, your filter uses flimsy plastic.

As far as the "study" you all keep referring to, there is no part of that study where the guy actually tests the filters for well, Filtration!. He is a fan of old mopar K cars cutting open filters and offering a very unqualified opinion, nothing more. There is no part of the study where he tests filtering efficiency or capacity.

To the poster, if you want to try a state of the art extended life oil filter, email you address to me at Jay.Buckley@honeywell.com and I will send you a case of them.

This is getting interested. fight of the oil filter companies

Except Amsoil is not a filter maker, they slap their name on someone elses filter. This is not a "battle", we will be sticking to engineering facts and science.

Getting back to the purpose of the thread and away from opinionated comments, where do K&N and Royal Purple fit into the oil filter mix in terms of quality?

I know AK bought K&N and a few others like that particular brand, but I was leaning more toward buying Amsoil or Royal Purple. To me, both look like quality filters, but I'm no expert.

Also, I can't find Royal Purple's API group number anywhere. I've heard that it's in group IV, but I've also heard it's in group V. However, I also read that Group V oils are reserved for air compressors and similar motors because they're not compatible with petroleum-based fuels and can actually damage auto engines.
