If you do a Google search on oil filter brands, there are a number of sites by regular car nuts that take apart various brands and look inside, see how well they are made, etc.
The ones that I recall being rated by and large as "the best" are the AC Delco, Wix, Mobil 1, and Purolator PureONE filters.
I always stick to OEM filters due to lack of info to make an informed decision. Main issue is the bypass valve; there's ZERO info on their psi rating, and that's crucial IMO. But also lack of info on flow rate, etc. This is one of the very few maintenance parts I stick with OEM.
Why buy an expensive A/M 'premiuim' filter if it's bypassing its media early??? Or like the K&N air filters, which flow more air than the engine needs (and more dirt), but with oil instead?? I just don't know to justify any of them.
Having said that, AC Delco has TWO filters, PF44 (or 46??), and UPF44/46. I use the cheapo one because it's the only one available locally, and change it every 3 to 5K miles, so why throw money away. But if I wanted a 'premium' one, I'd use the AC Delco UPF. Later gang.

FYI.....The Ac Delco UPF "Ultraguard Gold" oil filters have been discontinued for quite a while...seems like several years. A person might find old stock but that would be your only chance to get one of these particular oil filters.
Wix filters by CARQUEST. Look inside they are great filters.

Sigh, what a waste of quality synthetic oil. You aren't even getting good use out of it. This has been discussed elsewhere, if interested, use the search engine.
I just checked out the Amsoil website and they recommend changing their oil filter after 15,000 miles (severe use), 25,000 miles (normal use) or 1 year, whichever comes first when using their synthetic oil. I don't think I could go that far even though they say they will cover your engine/trans/rear end if their product(s) was the cause of component failure. With all the limitations outlined in their warranty info you'd catch hell trying to prove that their product cause the failure. I normally change my oil and filter around 10K when using synthetic oil.
