Message According to the FSM, Oil PSI when fully warmed up at idle may be as low as 11 psi. Oil pressure should rise to around 60 psi when holding the rps at 3k with no load.

Oil pressure will always be higher when cold.

Sometimes my gauge will get a little stuck but then I just floor it a sec then its gets unstuck....

The oil pressure sender unit is known to fail as well, along with issues with dirty connectors.

Clean OPSU connectors, change oil and filter, if your oil pressure is still really bad then you could change the oil pump and bearings.
