Now follow this advice to the letter ,go to spares shop and buy a nice big tin of STP oil additive ,use a funney in the oil filler to add the additive and leave the can to drain overnight as its very thick ,no slick stuff or a graphite additive just STP then as the light will stay off for a while you trade the car in quick .

SOURCE: 97 wrangler oil pressure drops when engine is at idle

check the engine oil level... you could possibly need to replace the oil pump soon... if you do not live in a cold climate i would consider using 30 or 50 weight oil. do NOT use that in a cold climate as the oil is like molasses when it gets cold.
that's only temporary. one other thing to consider is a clogged oil filter... when was the last time it was changed ?

3.5L V6. Why does oil pressure light turn on intermittently?


1. As a basic measure I would make sure the correct grade and spec oil is going in the engine. You can no longer trust that a local mechanic or even a dealer service center will necessarily use the required product as stipulated by the manufacturer. It is always better to buy and supply your own so you know the correct product is being used.

2. I would not assume there is a problem with the oil pressure warning light even though there could be.
The first thing the mechanic should have done when you reported the oil pressure issue is to hook up an independent mechanical oil pressure gauge and check oil pressure when the engine is hot at different RPMs. Any oil pressure issue will usually show up at idle when the engine has been warmed up properly and the engine oil is hot (unless you have some kind of intermittent oil pressure relief valve that is sticking). Just replacing parts without actually knowing what the oil pressures are at different RPMs is being sloppy and negligent.
This is what you need to do now. Contact a business that can hook up their own pressure gauge to your engine and have them check the oil pressure readings at various RPMs when the engine is fully warm. If there is a low oil pressure issue it will show up on the oil pressure gauge. As you have a new oil pump there should be no issue now with oil volume or a sticking oil pressure relief valve which on your engine should be part of the oil pump assembly.

3. Worn engines will not be able to sustain required oil pressures. Oil pressure is not produced by the oil pump. The oil pump produces oil flow but the resistance to flow is what produces the oil pressure and that resistance is created by fine clearances between operating engine parts especially on the crankshaft and components connected to it. Once the engine wears the clearances increase and the oil flows past the parts much more easily and produces/builds much less pressure.
How well your engine with over 90000 miles has been maintained depends on how often all the owners changed the engine oil and filter , whether they kept the engine oil level up to full (most owners rarely ever check oil levels between services) and whether they always used the correct product. Manufacturer oil change intervals shown in service schedules can be 10000, 12000 miles or more which is much too infrequent for the type of use 95% of private vehicles experience which typically are on the severe to very severe use end of the spectrum. Engine oil typically needs to be changed at least at half the mileage shown in service books (at least twice as frequently) and thus at least every 5000 miles if you want your engine to last.

Oil light on after engine warm-up on idle


this means a mechanical gauge test is required to check actual pressure warm idling if low below 20 psi then the oil pressure pump relief is stuck open or engine bearing are worn

Low oil pressure


The light should come on when oil pressure drops below 5psi (us).
The oil pressure could actually be low, or the switch could be faulty.

Oil light comes on when idling oil level is good


faulty oil pressure switch (cheap), worn oil pump (not pumping enough oil at low revs) but most likely worn shells or crankshaft (allows oil to pass too quickly lowering oil pressure - just not noticable when the engine is reving 'cos there's a lot more oil bieng shifted by the pump)

My oil light comes on at idle speed in my SantaFe 2006 CRDi engine


This is not necessarily a problem. If the oil is at correct level and viscosity grade, and the light always goes out with a small (not large) rise in revs, then it could possibly be OK. An engine does not need much oil pressure at idle, say 600-800 RPM.

It could also be a faulty sender unit on the engine, a worn oil pump, or a faulty oil pressure relief valve on the oil pump or in the filter.

To be sure, get an oil pressure gauge fitted to the sender outlet hole, and see what the reading is at various revs. If there is indeed a pressure problem by the gauge, try first a new oil filter. If not it is probably a faulty sender unit.

The oil light keeps on flickering even though I checked the level and it's at the correct level. I even checked all other levels for all other fluids and they are all correct. What can be the reason that...


There are a number of reason that could cause this: bad sensor, low oil pressure, wire rubbed and grounding out.

You need to screw out the oil pressure sensor and screw in a pressure guage then crank the car and observe the guage. It should stay above 20 psi at all times.

Does it flicker when idling or driving or both?

BMW 318iSE (1999) engine warning light


That sounds like you bought big problems. Oil ights indicate low oil pressure= BIG BUCKS. I would have a qualified repair shop check it out, A shop that specializes in BMW. If you are lucky, maybe the oil sender is just bad. They can also check out the Ck eng light. But the oil light is priority one.

1989 honda accord lxi fi oil light


Sounds like there is an oil pressure problem. Now this can be due to several factors. 1. low oil level in car
2. bad oil pump
3.bad oil pressure switch /sending unit
4. last but not least check oil filter and make sure its not clogged.
worn engine main/connecting rod bearings.
have pressure checked with a manual guage at oil pressure switch for the correct pressure. If that's good then the switch is bad and problem solved.
if it low then you will have to check pump and bearings. Contact if you need more help and thanks for using FIX YA
