NO OIL PRESSURE

[BuckeyeButch]

After driving about 400 miles after oil change, I got a RED no oil pressure warning while driving.
I checked and it was between 28-35psi depending on RPM. I didn't hear any noise, so we stopped for lunch. After eating I checked the oil and under hood NO evidence of a problem. Fired it up and ALL was good for the next 150 miles home.
A couple days ago I got a Aux switches not working due to low voltage, now this is a daily Driver, wondering if it's a battery issue, it's a 21 will be 4 yrs old May 17th.

Who did the oil change? I would be checking to make sure the gaskets are installed correctly and filter cap is tight.

Four years on the original batteries is doing quite well. I would plan on changing both of them soon. Be sure to fully charge them before installation.

Check oil filter torque.

Probably not the most likely scenario but there is a YouTuber with a 1500 who saw the same thing. Oil pan had black goo that kept sucking up and blocking the pickup tube. I have read that gen 3 motors have the EGR after DPF to help lower engine in oil. No expert just what I have read but may be worth keeping an eye on the pressure.

For reference. My oil pressure at idle fully warmed up is 17-18 psi. Some aftermarket filters can gives you issues with low pressure due to the smaller output oring isn't seated in far enough.

I did and have done it many times without troubles.
I double checked everything when I got home, all was good.
Used a WIX filter as I did the previous time.
