Oil pressure reading

[Haredawg]

Just got a 92 Loyale that has a oil gauge that goes from 0 to 80 lbs with 45 in the middle anyhow this is the first car for me with this gauge so I need to know if it's working right.Upon start up and driving the gauge is reading 45 lbs then seems to settle down to about 20-25 lbs but then while stopped at an idle the pressure drops to almost 0 maybe 2-3 lbs then when I accelerate the pressure goes back up to about 20-25 lbs is this normal or does this mean I have problems thanks Steve ( what should the pressure read )

that's normal.

 

if you have the owners manual, read it and it will tell you. might want to pick one up if you don't have one.

Factory gauges aren't really known to be all that accurate, so you may want to install an aftermarket one, even just temporarily. A good rule to follow is 10psi for every 1,000rpm.

On mine, cold start and highway peg the gauge past 75psi, hot idle is around 25, and I have checked the accuracy of the gauge.

I have the same problem with my Subaru. My temperture guage does it aswell. It will move up to red and then gradually move down again. I dont think its something to worry about, but if any one knows what it is let us know.On a side note does anyone know what a flushing sound means on the passenger side of the engine is?

It sounds like the thermostat is sticking, letting the engine get too hot before opening.
