another oil filter thread. youtube tests.

That's for Gen3 V8s.

For Gen4 V8s, Wix 57502 ... or 51392? ... or 57060? There may well be something wrong with this info, please doublecheck it.

Wix 57502 are for a lot of ford V6 engines. Wix 57060 is the correct one ( I use wix 57045 - longer version)

here's what I have saved in a note that I've crossed on the last year or so. most info from the wix site.


stock length but higher bypass pressure the LT's switched to
3.45in 22psi bypass wl10290(xp)
ac Delco pf64
amsoil EA15K50 3.4in bypass 18-24

longer high psi
4.09in WIX 57502XP 22PSI 4.09 inches Synthetic 10-12GPM 22x1.5MM 21micron

4.4in, pf63, wix wl10255 bypass 22psi, 21 micron
amsoil EA017 4.45in bypass 18-24
fram fe10575 4.5in or xg10575 4.0in


longer lower psi
4.8in flush with (yukon) pan bottom 57045 bypass 12/15psi 21 micron


no bypass
4.5in 57026 (xp) (long # 765809570269)

but anyways, testing. I thought they did a good job selecting the test oil and using the different size particles to put into the oil.

kinda impressed how good some filters did removing the smallest size from the oil and by how some of the others didn't remove much if any of the small stuff. Definitely some black magic to making media. they kinda all look the same when you cut them open.

The new LT engines use the oil pressures just a tad different than the LS2/LS3 as
far as controlling DOD/AFM and VVT
They also use a different oil pump - variable pressure or volume (not sure which)
which is "supposed" to help with the oiling issues of the Gen 3/4 engines
So I'd expect a different bypass pressure etc to be used now.
But our engines in 'this' section are gen 3 or 4's

yeah, but I don't believe having a few psi higher bypass is bad for the engine, and I'm a bit of an odd ball case, my 2011 yukon has a variable displacement oil pump.. thing runs 60psi on all but the hottest days of hours long driving, then it will drop to like 45 at 600rpm. so I like the idea of higher bypass for it, plus I don't believe it can do anything but help.

my other car (ls3) I run a little thicker oil due to very high oil Temps, I try to back down for a few cool down laps at 300deg. so higher bypass psi for the cold starts can't hurt because i get lazy and drive it around on it haha. gm didn't switch the c7 filters till a mid Gen run, the engine didn't change, just the oil weight. they moved to with to a 0w40 daily use and I think it's 15w50 for track days to be dumped before daily driving again.

either way, that's just why I have the notes. pick whatever feels right.
