if it's a 2011 did they switch to a digital gauge, i believe from a past post the the 2010's have an analog signal that the computer sends to the gauge and it is only to show positive oil press, not actual oil press.

Since at least 97, they are dummy gauges. If there is enough pressure to keep the light off (about 7psi), then the gauge will read somewhere between 1/2 and 3/4 on the gauge. Too many idiots used to complain about the gauges fluctuating so they did this keep people from going to the service dept for no reason.
