2020 silverado 1500 5.3L 117k miles
unknown mileage in service, 15% left on OLM

out/off: 8 quarts dealer bulk 0W-20 with ACDelco PF63

in/on: 6.5 quarts Valvoline R&P 5W-30 and 1.5 quarts HPL EC30 with Carquest Premium 84502

filter looks okay. note the ADBV photos and why i don’t like anything but silicone on the fleet. it stuck in positions it was bent into.

Nice photos. Thank You for cut

Sounds like those non-silicon adbv's get stiff. Not only will silicon stand up to the heat but it's more flexible to begin with so win/win for sure as you noted. Media gets a bit dizzy around the glued seem but rest of it looks good. I think these delco's come out okay overall most of the time.

R&P + EC30
Will patiently await your results.

A bit off topic but how does the truck run on 5w30? I have a 19 Silverado 5.3 and have been debating running 5w30 instead of 0w20.

valve train clatter is reduced with 5w-30. other than that oil pressure stays about the same on the dash. the 6.2 that i put HPL PCEO 5w-30 was going down the road at 60-65psi checked with my scan tool.
