SOURCE: low oil pressue light at low rpm

wrong oil need 10w 40 weight caster oil is best. See right now you have thin oil and in hot weather and hot motor temp . It just gets thiner . now with 10w 40 you will bring it up a bit thus lowering the oil presser and bringing it to a happy medium .

SOURCE: How low is my oil when the light comes on.

No, not normal at all! If your oil light comes on, stop driving before you ruin the engine! The light indicates not necessarily low oil, but lack of pressure. Either way, you need to get it fixed. If you add oil and the problem comes back soon, then you have other problems, like leaks, or a failing oil pump.

SOURCE: oil pressure gauge reads low

Jim, you are going to have to look at the oil pressure sensor. It may be bad or it may just have a loose wire or bad wire. This sensor picks up the oil pressure and activates your light.

High temp low oil pressure light comes on after driving for a few minutes, then off when engine at driving rpm. At stop light (idle or low rpm) light comes back on. Normal driving it goes out.


You need to find out why you have low oil pressure. It is normal that as engine rpm's increase, the oil pressure will rise- the oil pump is moving oil faster. Even though your light goes out, you could still have critically low oil pressure. There should be sufficient pressure at idle to keep the light off. The light will come on when your oil pressure is almost nil- I believe for some it's as low as 8 psi. Normally, oil pressure at idle is specified anywhere from 15 to 40 psi. You would have to check specifications for your Expedition. To verify oil pressure, hook up a mechanical gauge at the oil pressure sending unit on the engine block. Check with a local shop.

The causes run from easy, simple to budget busting ruin. Low oil level, wrong grade oil, real old oil, oil leaks, internal oil leaks, worn oil pump, worn crankshaft bearings. It was pretty common on older very high mileage cars to have a fluttering oil light at stops and idle. It was time for a rebuild, or time to look for another car.

Oil light comes on when i put the clutch in and come to a stop


check the oil level in the sump. Ensure that the idle RPM is at 750rpm or above up to 1000rpm. Check for the correct grade of oil in the engine for you atmospheric temperature.

1999 chrysler sebring low oil pressure at idle


It may be the oil pump. If the gauge is going up when the rpms increase it's probably not the gauge or pressure switch. If the computer senses the oil pressure is low it will shut the vehicle off to try to save it's self from catastrophic failure. Also it may start cranking longer before starting. Thats it building oil pressure before the computer will let it start. Make sure oil is full, clean & thick.

Have a reputable garage check the oil pressure with a manual oil pressure gauge. Very well may have worn internal parts, or weak oil pump. Thats the only way to know for sure.

Possible that the OIL filter is clogged and is reducing the pressure due to this when the engine is idling or in low RPM. So before you run the engine further and make it more damaging , it is worth to have the engine oil / oil filter changed. If there is still no result, check the oil pressure switch. If not the oil pump can be faulty. This needs a technical help and should be consulted.

I would suspect that you have a weak or failing oil pump, however before condemning the pump I would do a physical oil pressure check with a gauge. Oil pumps are not easy to replace so lets make sure it is the problem before replacing it. For reference yours can be done with the motor in the vehicle.

Physical Pressure Test:

This may require you to tuck a oil pressure gauge under the driver side wiper arm and go for a short drive to make the situation replicate. Depending on how you hook up the gauge (in place of oil pressure switch) the light will be on full time during the testing and this is ok. If you can replicate this symptom that you are reporting in the drive way in gear it is desirable as you can better read the gauge.

The oil pressure should be:

3.0L = Oil pressure should be 6 PSI at idle and 35-75 psi at 3,000 rpm with engine at normal operating temperature.

3.3L = Oil pressure should be 5 psi at idle and 30-80 psi at 3,000 rpm with engine at normal operating temperature.

You see that there is a large "in spec" region for the 3,000 rpm range as listed. I would look for the pressure to be at the higher end of the scale and the idle pressure to be right in spec. If any of these pressures are low I would suggest changing the oil pump.

If your motor is one that I have not listed here please comment back and I will provide the appropriate spec per the motor in your van.

When i come into a complete stop the oil gauge goes down.


If it's your oil pressure gauge, that is usually normal. The pressure will rise and fall with the RPM's of the engine, since the oil pump runs off of the engine itself.

Do you have a CEL coming on when it does that? If so, got to Autozone or Advanced, and get the codes from it, and myself or someone on here can help you fix it.
