Oil Pressure on GM Gen 5 V-8's

[Snagglefoot]

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.

Hot idle - 30
Highway cruising - just a touch over 40
Over 3,000 RPM - 70

Hot idle: 25
Gruadally builds to ~40
Over 3500 rpm: ~70

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