my oil light started to flicker after I had an oil change took it back they had it 3 days only to then tell me they don't know what's wrong but charged me 560$. They changed the oil AGAIN even though they were the ones who did it originally less than a month before, replaced all my spark plugs, and changed the oil sensor which didn't help cause the light still is flickering. It only does it when my car is in idle and the car seems to be running fine besides that. My dad was my mechanic but he died recently and now I know these guys think I'm just some dumb girl who doesn't know anything about cars, and they are right.

Two reasons for your oil light to flicker.

1. low oil pressure, meaning you need to top up your oil.

2. faulty oil pressure switch, meaning you might need either a new oil pressure switch if it is defective. Or, you have sludge in your engine and that is clogging up the oil pressure switch causing a false reading. Either was a new oil filter and some fresh oil may cure the problem. If you are going to this length, then while the oil filter is off and your oil is drained, get some fuel and pump it into the engine through your filler hole. Let it drain down and flow out the drain plug. You will probably notice how black it is. You can do this a couple of times. Do not start the engine, while it has no oil in it.

Then, while the oil filter is still off, and no oil is in it. Take out your oil pressure switch often it is at the back of the engine. You may notice some black sludge come out. Then pump fuel up through the hole that the oil pressure switch came out of, fuel should or may squire out where the oil filter goes, this is both normal and OK. Let the fuel drain out the sump plug hole. Take a bit of time to wash out the pressure switch if it has a hole in it. Some do some don't.

Then, put the sump plug bolt back in if it has a renewable washer replace it. If it is copper or aluminium you should be OK. Spin on a new oil filter and tighten it hand tight and then about a 1/4 of a turn more. Fill your engine with the recommended oil. Do not worry about any residual fuel left in the oil, as it will burn off when the vehicle gets up to operating temperature.

Let the engine run for about 10 minutes on idle. Make sure the oil light goes off in this time. Turn off the engine, then restart it and see if the light goes out at idle. Drive the car at highway speeds. See if the light comes back on. If it does, then I'd assume that the oil pressure switch is dead. Replace it with a new one. You do not need to drain all the oil to do this. But be prepared for some oil to drop out the hole, if it is sludgy, replace the switch anyway. Test drive and check, if no light then you've fixed your issue. You may also need to scan your car and clear any codes.

I replaced my oil pump, cleaned all the internal oil pipes....and it seized. Then sent it to a mechanic as I obviously did something wrong. Low and behold the oil light comes on again. The mechanic is dumb founded and I am out of pocket. No better than if I did it myself. :(

Check fuel pump for oil leak where it attached to motor .that was my problem on 86 Ford

さんによる

If it is a diesel and modern, it may have a DPF fitted. They inject extra diesel in to the combustion to burn off particulates that have accumulated. A side effect of this is diesel in your engine oil. But if you drive at highway speeds this may not be such a problem. Long slow and short trips often cause this.

My 4m40 was flickering oil light when idling and hot. The light was going off when the engine rerves up to 2. I changed the oil pump but it is still doing the same problem. Pls can someone comes with a good idea.

the pcv valve tends to fluctuate engine pressure

James, check the sensor bud. It may be bad and not getting correct oil pressure reading
