Losing Oil pressure

[b00zt3d spyd3r]

When I first start my car, oil pressure is good, but after it warms up to operating temperature it loses pressure. But only at idle. When I accelerate it goes back up if I stop at a stop light it starts dropping again. Any ideas?

That's normal. Once the oil heats up its not as viscous/thick and oil pressure should rise with RPM so that's good. Just make sure its not following below whatever your engine specs are.

Well I'm going off the stock gauge but if I idle long with out accelerating it'll bottom out on the gauge

The stock gauge isn't accurate. You need to get another gauge that reads pressure.

Yup stock gauge is as accurate as a gm oil pressure gauge hah

Best off just going after market (non manual gauge . Electronic is the way to go )

It's normal to see the gauge goto the first tick at idle hah
Hell I've owned this car for three years an it's always been like that

If I Remember correctly from the first tick to the second tick is between 1000 rpm - 3000 Rpm
And anything above 3000 should go past the second tick not that you should trust that oil pressure gauge
