The FILTER stays full...but the oil galleries above the filter can drain down to the level of the filter.None at all. It doesn't need an anti-drain back valve because the filter mounts vertically and doesn't drain with the engine off.

That filter is a beast.. 4-13/16" long; but with those metric threads it's a no-go for my 2006 LQ9. What LS engines are you using it on? Not that I put a ton of faith in OReally's online compatibility chart but it just shows a bunch of Mopar stuff.On my newer trucks with LS engines I use WIX 57045 oil filters. They are twice the size of the stock filters. I also machined a new threaded boss with the same M22 threads to use this same filter on my 91 K1500. It is almost the same size filter that originally came on my 350. So now I can order them from rock auto for 3 trucks. I use a 51794 two quart filter on my 454SS and my two 6.5 Diesel engines.
I was very disheartened by the handful of videos on YouTube that show what's inside of Mobile 1 oil filters. They show/compare several different brands. I was a fan of Mobile 1 (still like the oil) until I saw that the filters are not as good as SuperTech (Wally world stuff that I EXPECTED to be junk). The SuperTech is nearly identical to Wix.When I sent Blackstone a sample of my oil (Valvoline VR1 Racing 10w-30 conv) it had 3,720 miles on it. It started with a TBN of 8.0. After the miles put on it it had only dropped to 6.2. Anything above 1 is good to go. Also using a Mobil 1 Extended Perf. filter
No reason any decent oil today cannot go at min 10k miles.
Far as I know, Wix "makes" oil filters, as does Baldwin. Wix provides--or provided--filters for NAPA and CarQuest, among others. I don't know much about Baldwin.
Champion Labs is one of the suppliers for the hundreds of other brand names. And they've got more than one "grade" of filter--the old "good/better/best" system. A "best" version of a Champion oil filter is a reasonable product. I don't want the "good" one, though.
I was pretty disappointed when I saw expensive K&N oil filters that were made in China.
OK, going to be the year/generation difference, then. A GMT800 would use the 13/16-16 thread.I use them on my wife’s 2014 Tahoe with the 5.3. Also on my 2018 2500HD with a 6.0. They work well with No issues.
