Factory Rallye Dash Oil Pressure Gauge Reading

plymouthman72 said:

I don't believe I have an issue or anything but wanted to check if anyone knew how to convert the lines to actual oil pressure readings. When the engine oil is cold it likes to stay at the high end of the gauge but will come down more to the .5/.75 mark under acceleration. It runs fine as is but was just curious. Thanks for any input!

I don’t think you have an issue, but that gauge is terrible.

I have two AutoMeter Ultra Light Gauges mounted on my center console

https://www.autometer.com/2-5-8-oil-press-0-100-psi-sse-ultra-lite.html

Oil and Temp


Cold at 75 psi idle
Hot it will drop down to around 25 psi idle at 600/700 RPMs and step up to 75 psi going down highway around 3200 RPMs



Anyways my factory gauge like the box picture was used with Tach/Clock option
75 psi = 4th line pointed at U in Pressure
25 psi = 2nd line pointed at R in Pressure

I stare at these damn gauges constantly more then I should with my 383/432 Stroker
