I'm thinking I should get the PF64 back on there and take the up on their offer to swap the oil out again as a result of the 'clerical error'.
Most quickie lube shops aren't going to care or even fully understand bypass psi like GM does and we do, so a lot of cars will just dumb it down to whatever fits. But we can do better:
Hastings LF630 with a similar bypass psi of 20 psi, close enough.
Same bypass psi for Balwin B7422 as the Hastings, so either is the same here.
Fram Racing HP18 has a 22 psi bypass (and a screen over the bypass valve, very cool, very sturdy oil filter).
If you can go oversize slightly, the Wix 57502 and 51372 both have a 22 psi bypass valve.
(Notice the Wix 57060 is the right size, but it's bypass psi is too low at only 12 psi.)
Fram Racing HP19 is oversize, 22 psi bypass.
AC-Delco PF63E is oversize with a 22 psi bypass.
Of all the ones above, Wix has the most efficient filtering, but they are oversize, so can't be used by all if interference issues are there.
Fram Racing oil filters do OK on filtering efficiency, 94% at 20 microns, not too bad, so a good but expensive choice.
Hastings and Baldwin might be using a nitrile ADBV instead of the desired silicone ADBV the Wix and Fram Racing oil filters have.
AC-Delco PF64 (and PF63E oversized one) has nitrile ADBV and I think they have paper-only media, not great really.
For the nice Cadillac ATS, a very expensive car deserving of the best-constructed oil filter with a correct size & bypass psi (22 psi), I'd just get the Fram Racing HP18 (amazon or Summit Racing online maybe). Certainly filters better than a PF64, and built stronger too, with a silicone ADBV too.
I like the high 22 psi bypass, although Fram Ultra has the best media. Can't use a Fram Ultra due to bypass psi though!

The WIX website lookup reports WL10290/XP as the filter for my application, and it does indeed have the 22psi bypass spec. Any reason this wouldn't be a solid choice? Do we have C&P's of this filter?
