Found lots of threads about low oil pressure on the dash gauge. They all seemed to resolve with replacement of a new mopar oil pressure sender or the thread was abandoned. I may not be so lucky.
In my case:
What say the brain trust?
Should I not sweat it since the car behaves fine otherwise? Am I good to stick with that 20w50 in there or is that an ill-conceived band-aid?

In my case:
- Red Check Gauges light at cold startup & 0 oil pressure on dash gauge. No weird engine sounds, driving characteristics, or engine codes
- I replaced the sensor with a new mopar sensor from Rock Auto.
- On cold start, dash gauge reported 30psi at idle. But, oil pressure fell as the car warmed up. Once at temp, oil pressure showed 0psi & check gauges at idle and 10-20psi when on the gas.
- Shop confirmed that a mechanical oil pressure gauge agreed with the dash gauge. They also said the valves, oil pan, and oil pickup screen were full of sludge. Thanks PO.
- Shop threw in a new oil pump, flushed the oil, and replaced with some sort of Liqui Moly 20w50 oil and an additive to help with the sludge.
- Now, dash gauge shows 40-50psi on cold start idle but once up to temp, it still falls back down to 0psi + check gauges and 10-20psi while on the gas. Still no unusual engine sounds, driving characteristics, or engine codes.
