Oil Pressure low

I am wondering what is the correct oil pressure reading for a 95 Chevy S-10. My oil pressure Idels around 30. When I am driving it goes up to 40 but never passes. Lately at a stop it has ben dropping all the way down in the red to around 10. Could this be a faulty sending unit or Oil Pump.

Neither. Could be a normal condition.

Do not rely on the dashboard gauge for accuracy. Get a hand held pressure gauge from Autozone (they will rent you one), and check the pressure versus the spec in the service manual or autolibrary.org below.

Like Joe sez, manual check pressure, however I have driven several 95 and 96 models like that with 4.3's. The dash guages on them read 60 at 70MPH and about 35/40 at idle with 5/30 and 10/30 oil. Bear in mind, those OEM guages are not a high price guage.

Just another thing to confuse you. Yes, follow all the good advice above first. when you want to start changing things, I used to have a S-10 a few years older than yours. Before I started to learn how to do some of my own work, I had low oil readings, and went to a dealer. The mechanic said 'we replace the sender units by the bushel full', and it might be the cheapest and easiest thing to change.

While the senders do go bad, there should be no need to change parts without testing them to damn them as bad first .
