Lotsa disagreement on your last statement…I always put some oil in the filter but years ago I used to completely fill it up to the point of if I didn’t hold it straight up and down it would spill out. I’m too old to be juggling s h I T around under there. Lube the gasket and send it.
Disagreement on pre filling the oil filter? Really? Is it by the same guys arguing which is the best oil and filter? LOL
I'm kidding!
The oil filter just screws straight upwards on all the GMT800s (just looked at my suburban 4x4 to confirm it's the same as the 2wd.) I only fill it about 3/4 full and lube the seal.
But my k3500 OBS 5.7 SBC Vortec has that angled adapter to clear the front driveshaft. Now THAT creates such a mess! I've only changed the oil twice on that truck, which is not a daily driver and is hardly driven. First time I did it I thought it was a stupid design. I'd spill the oil if I tried pre-filling the filter.
And we also own a 2013 minivan with the 3.6 Pentastar. That one has that oil filter cartridge on top of the engine. I obviously don't pre-fill that one either.
So I can see why the disagreement now that think about it...
