oil pressure bounceing
HI new to the site love it so far. I have a 2000 F350 with a V10 and auto tranny with 119,000 on it. When the truck warms up and I am In gear stopped at a stop sign the oil pressure guage semms to bounce never into the low side but still bounces. When I shift to newtral the oil pressure stabilizes on the high side It also runs on the higher side of the guage when going down the road. Engine does not use oil and does not knock on start up so I think the oil pressure is ok thinking maybe it is a sending unit any help will be greatly appreciated.

I'd think it was a voltage issue, contact problems should be more erratic. So when the alt is not putting out as much power, the oil gauge reads low and when it's putting out more power the oil gauge reads high.
Do any other gauges act similar?

The oil pressure "guage" in a ford is really a switch. Over 4 psi and it closes, and the guage will read in the "normal" range. I've seen articles describing how to convert it to a real guage. As far as I know, this is still the case.

Do you have links to the conversions? I would love to put my autometer sender in place of the stock one, then (maybe with the help of a trim pot or resistor) use it drive both my autometer and stock gauge.

It involves using a real sender in place of the ford idiot-light sender. Then, there is a resistor in the gauge (on the earlier years, anyway) that you can short out and the gauge will read full-swing. Otherwise, the gauge will only go to the stock "good" reading about half-way up the gauge.
Glad it was the sending unit.
Otherwise, it would have been the engine's oil pressure was bouncing right around 4PSI - which is not good.
In other words, it was acting like an idiot-light flickering.
