Your oil pressure should be a lot more than 7 lbs, your oil filter may need changing, or your oil pump could be the problem ....hope this helps....cheers

If you are using 5w-30 try going with 5w-50-they do have very low oil pressure at idle, and if you have any clearance issues the sensor will detect a reading that is enough to trip the warning. 5W-50 will not damage your engine but ill provide enough viscosity to increase readings. My 2001 has 120,000 and I run full synthetic, 5W-50 and live in the Northeast US, so I see temps from 0 degrees to 100+ with no issues at all.

Oil pressure warning light


The oil pressure light coming on at idle is not a big worry, so long as it goes out as soon as revs rise.. First step is to remove the oil pressure sender unit and screw in an oil pressure gauge. a mechanic can do this for you. This will tell you if the sender is faulty (common enough) or the oil pressure is low. A rule of thumb is to have about 10 psi per 1000 RPM in the normal rev range

If it is indeed low, possible causes are
- worn big end or main bearings (the car is old enough)
-faulty or weak over-pressure relief valve in oil pump
-worn or faulty oil pump
-blocked or sludged up oil passages
-blocked or sludged up oil pickup strainer mesh in sump

Some of these can be investigated by putting the car on a hoist and removing the sump

Low oil pressure indicator at low rpms (idle) '97 olds V8


Low pressure when at idle, after the engine has warmed up and the oil has thinned, indicates that the oil pump is worn and needs to be replaced.

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.

00 lincon navigator 5.4 oil pressure drop's low and light comes on , engine idles rough when pressure drops ,then pressure return s to normal range ,light goes out ,engine runs perfect. Is it my oil


Sounds more like an engine idle issue than a oil pressure issue. If the engine idle drops too low, the oil pump cannot provide sufficient oil pressure. If there is no oil light when the engine is idling normally, then there is no problem there.

I changes oil in my 1997 aurora and i put 5w 30 back in. after it warmed up the low pressure light comes on at idle.What might be the problem


with it being a 97, the oil pump could be worn if high milage. thus causing less pressure. try 10w30, it wont hurt a thing.

My low pressure oil light keeps coming on when i stop and i just got my oil changed. The oil is not low. What could be the problem?


Hi,
That means LOW PRESSURE , not low in volume. Pressure is measured in PSI. The reason that your light comes on when you are at a stop is because your engine goes to idle at a stop and would normally have lower pressure. That doesn't mean you should get a low pressure light though.. I would have it checked by a pro right away as this could be your first warning before a serious problem.

On my 2001 olds aurora 4 liter engine when I come to stop at traffic light low oil pressure light comes on until I bring RPM's up,is there a way to increse idling?


Sounds like your oil pump is bad - I'd have that checked. You can adjust throttle via the screw on the throttle line (look for the intake and there should be somthing resembling a bicycle cable going to the round throttle body). Tighter = higher idle. Fix the cause as soon as possible as this can destroy your engine quickly.

Thicker oil is all you need. 5w30 is too thin when it warms up and the sensor cant pick up the flow going past. 10w40 should stop all the issues
