2021 5.3/Oil pressure, how low is too low?

[VAguy68]

2021 5.3. I'm seeing what looks to be around 26 to 28 lbs hot idle. Seems a little low. Highway 75 mph I'm around 60lbs. Normal?

I see the same thing on mine although I’m not sure what the exact value is. Usually it’s around the first notch or sometimes a little below at idle after it’s good and warmed up.

I wish there was a way to get the digital readout on there. My old 2017 GMC Acadia Denali would show me a little more info under the info pages vs my ‘21 Tahoe Premiere.

Course the tach barely registers any RPMs either at idle…it should show 600 or so at idle (based on my previous vehicles) and the needle looks like it’s at 100-200. I suspect maybe the needle is off unless that’s what they all show???

Your fine. You would be shocked at what GM calls minimum hot pressure... :0
