oil gauge antics

Unknown

My '23 has an oil gauge problem. When I start the car, the gauge

registers nothing, sometimes for several minutes. Then the

gauge "notches" up (like the second hand on a watch). After I shut

the engine off, the gauge continues to read (at about 4) for fifteen

to twenty minutes. I know that I'm a little out of step with the

world, but whats up with my gauge? Is my oil line too restricted?

Where would it stop up?Zeke
