I just bought a 2016 Colorado Duramax and the hot idle oil pressure is only 13lpsi is this normal? It was after driving an hour so the oil was definitely up to temp

i also have a 2016 colorado, currently 72k on the clock. i run rotella t6 and hot idle oil pressure has always been 17 psi.
Since you just bought it, no way of knowing what oil its running. you could change it, and see it that improves the reading.

There used to be an old used car sales trick of putting heavy weight oil in to hide issues. Now I feel like I'm dating myself lol. Not blaming the sales place, btw. They just shine them up and maybe do some basic stuff - then sell them. Yeah, I'd get an oil change with the proper stuff and see what happens. You never know what someone put in there.

My truck at 18,760 mi runs 17 psi at hot idle with the 5W30 from my 2nd and last 'free' oil change.

I have owned a diesel Canyon 2015 since it was brand new. It registers 11 to 13 at idle all the time. I use turbo diesel Mobil one. It is awesome and driving at 75 MPH it is up towards 40 psi. Works for me.

5W30 euro-L - 15-16 psi for the first 3000 ish, but when it gets to 5000 ish on the oil change it is 14 -15 psi. I don’t think 13 is alarming.

The name of the game is oil getting to the right places. This is not your '70's oil. It's thin, but engineered to do the job of getting everywhere, even with engines set up tight for emissions. The shear stress on vital parts is less than '70's engines, and the parts are stronger. The "good ol' days", really weren't. My pressures don't get quite that low, even during idle periods during heavy towing. But IMO, it's fine.

Fine or not, I would rather see 60psi than 13 or even 20.

I have consistently gotten the "Low Oil Pressure" alarm coming on (over the last 3 months) when I'm offroading and come to a stop and idle. 6 or 7psi throws the alarm. I've seen as low as 5 psi.
The dealership has tried to diagnose this problem 3 times. Even contacting "TAC" last time. Each time they could not reproduce the problem, even though I have it documented.

Any help with others having the same issue?

Since you're offroading, are you getting hot? Are you using oil? Any power loss?

IMO, higher vis oil would help with the symptom, but not with any actual lower end problem. And you might not lube the tight places as well, especially cooler.

If there is a way to test the oil pump, that would be nice. Showing my ignorance of diagnostic techniques here....
