I have a question. My oil pressure is fine when I start my truck. But after I drive it the oil pressure drops. To almost nothing. Then when I am idiling it goes into the orange and the check gauges light comes on.
Do you
have the same problem?

Most common cause of the symptoms you describe is either worn engine bearings. With the high mileage you show, my first thought is; the motor is just plain getting tired. You can double check your dash gauge by removing the OP sending unit, and screwing a regular needle type liquid gauge in it's place but, you will find close to the same pressure reading. Hope this helps.
