The "E" at the end of the part number? That's for "environmental". It's the newer design of ACDelco filters that are made of more environmentally-friendly components.
Thanks for letting me know im buying a filter endorsed by AOC :rolleyes:

In all seriousness, I recall there being info presence or absence of the valve, and I really did not pay attention given the orientation of the 5.3L filter. Teats on a bore IMO.

I dropped off my keys to me mechanic.... I'll be out of town for a week ( on a cruise).... He's changing out my transmission fluid,etc, brake fluid, test out my 4wd ( I haven't tried it yet - 1 1/2 years owning the Yukon XL).... Inspect / measure brakes.....

I tried to spend $500.00, but couldn't get close to it. ( Good shop / very fair prices)

Changed the oil and filter went full synthetic Castorol Edge 5w30 WalMart online p/u in store $15 per 5qt. Removed the starter looking for slow oil leak above it. Seems like its the pan leaking from about 4 bolts in front. Cleaned it all up, put leak dye in the crankcase and will recheck in a week.​

After some curiosity on another thread, did some reading... And added some 2 stroke oil to my gas.

I ******* hate the fact that this works. It idles smoother, how I don't know. I cannot make heads or tails of it. I'd have a very weak misfire once every couple seconds that tended with the oxygen sensor voltage. It's gone. I ******* cannot even with this stuff......

So this thread got me curious: https://www.tahoeyukonforum.com/threads/getting-8-5-mpg-need-help.102485/

Reading: http://www.ls1.com/forums/f48/been-testing-oil-91206/

Some anecdotal stuff here: https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/5214715

That's about all I got for now. Going to run it for a bit and see what happens. Will be peering down my spark plug holes in a few thousand miles to see how it looks. Can't comment on fuel economy, my driving as of late has been too sporadic. Too many different conditions and driving scenarios.

Will run a UOA on it too but tbh I still have another year and a half before that would be appropriate because of an oil pump replacement recently.
