The oil pressure gage in newer F series trucks does not really indicate pressure. The gage is really just actuated by a pressure switch and is basically an idiot light that does not illuminate. You would have to hook up an actual pressure gage if you wanted to read real oil pressure.

Get a real oil pressure gauge and hook it up, it'll have instructions on how. The oil pressure should be 40-60psi while idling and the engine being warm. There could be a problem with your oil pump or engine bearings...better to be safe then loose an engine
