The GM Gen 5 V-8's (2014 and newer) except for the 6 liter which is still a Gen 4, apparently use a two stage oil pump with a higher flow rate and possibly a higher oil pressure. What sort of oil pressure do you see at constant highway speed. I'm trying to get at a sampling of 10 responses. Thanks.

Well I guess that wraps it. Thanks for the input. Amazing. I guess GM really wants that high oil pressure. Iím thinking this is part of the fix for the infamous lifter issues in the AFM system in the Gen 4 5.3 liter engines.
