My requirements are metal end caps, and a silicone anti-drainback valve. Of course a good filter element comes with those options. You can see if a filter has metal end caps by looking inside the center hole, and the anti-drainback valve can be seen through the small holes around the center hole. If it's black it's plain rubber which isnt as flexible and prone to hardening from heat and just time.
Wix of any filter is good quality, oreillys is the only store near me that sells them.
Purolator classic filters (white can) are pretty decent filters, still have a rubber anti-drainback and an economy style filter element. Purolator classic is the same filter a lot of $25 oil change places use.
Purolator pureone (yellow can) is their top model filter which has a silicone anti-drainback valve and better filter element.
Purolator Pureone is my preferred filter, but cannot be used for extended oil changes. The filter element is too dense for that. They rate pureone at a 99% efficiency over their classic at 97%. They have started selling a synthetic oil filter this year that I'm sure is on par with the pureone as far as quality goes, and is safe to use for very extended oil change intervals. It's capable of holding contaminants and not plugging or falling apart over longer use.
So wix or pureone for normal oil change intervals, and for extended with synthetic oil I'd use purolators synthetic filter. Frams are economy filters, it's just about quality that's all. They do sell a toughgaurd filter that is probably their best filter, along with their racing filters. Ac Delco is on par with fram's quality as far as I know.
