A couple months ago I noticed my oil pressure
reads 80, even when the engine is off but truck
turned to on. Last week right after an oil change,
when I accelerate the pressure drop to 0.
Sometimes it will ding and say low oil pressure, but
most times it doesn't. When I come to a stop or
after I'm at a set speed it shoots right back to 80.
Oil level is good and no wierd noises. 149k miles.
