So, I bought my wife a 17 F250 with the 6.2L gas engine (nice truck) but I noticed that every time I start it the oil pressure gauge goes to the same position and doesn't change a bit with engine rpm. If I turn the key to the on position the needle will go to that same postion for approx 10 seconds the drop to 0. If it start it, At idle
it goes to to the same postion before it stops cranking. Has anyone else noticed this?. T.I.A.
If a certain pressure threshold is met it will just show that same place on the gauge. If it doesn’t meet that pressure threshold it will show zero and give a warning.
I I don’t know what the threshold is for that application but they are typically really low, like 5-7psi.
I would like to know why they even have that “gauge”? Why not just leave it as an idiot light, could put something more useful there, or better yet have an actual oil pressure gauge.
99.9% of people would freak every time it dropped "too low" for them on the gauge. The average person has not been taught to understand the purpose of the gauge and Ford long ago stopped providing real oil pressure readings

As others have said, I would prefer an oil idiot light if the oil pressure does become an issue. and replace the "gauge" with something more useful, like an ammeter, considering the electrical load these trucks are under that would be of more value to me.
Ford has been doing this for DECADES, have a gauge on the dash, but just an on/off switch for pressure, that makes the gauge needle jump to the middle of the range and stay there.
Ford determined that buyers wanted a gauge, but also determined that the gauge had to maintain a certain level to keep owners from making unnecessary complaints about oil pressure fluctuations. So, they made the switch turn on with a minimum of 7 psi, with the gauge needle taking a set point in the middle of the gauge range, and thus reducing the unnecessary oil pressure complaints.
So, so long as your engine has 7 psi of oil pressure, then you are good to go, Ford doesn't want to hear from you!
Way back before everything on the dash became computer controlled, you could modify the gauge and change the pressure sensor to make the gauge really work as a gauge.
Seriously doubt anything like that could be done on these trucks.
All this talk about pressure.....yet no one has posted what the oil pressure range Ford states by the workshop resources is acceptable for the motors in these trucks.
You could either install an actual mechanical gauge or many of the better plug in diagnostic code readers will also display real time readings such as oil psi, temp, etc.

How would the diagnostic code reader be able to give an oil pressure reading if there is no sensor that reads a range of pressure?
The sensor in the engine is a simple on/off sensor.
