Got a new set of wheels!

God I hope so. I filled it up and drove 75 miles. The needle didn't move
Must be stuck ...... LOL

Maybe the reason it is overfilled is because the light was coming on.

Best to change oil & filter, fill correctly, if light still flickers install a manual gauge to see for sure what the pressure is.

My guess high mile engine and a weak oil pump

Idiot lights will come on at low pressure but might still be enough to lube it.

GM had that problem in the 60s when the cars were new
