Oil Light on Dash

Every couple of days, when I pull up to a stop sign or set of lights, the oil light will come on. However, as soon as I start moving again, the light goes off. This is not a daily occurence, and has only happened three times in the past month. I am not due for another oil change for another 2000 kilometres. What is the cause of this, and what can I do to stop it from happening? The last thing I want to happen is to have the car break down in the middle of nowhere, especially as we head toward the winter...

what type engine, how many miles, engine age?
Could be several things from a clogged pickup screen, failing oil pump, bad main bearings, failing sender unit/guage, on and on.

if it is a japanese import....probably the oil pressure sending unit is no good.
If it is a domestic.....probly has excessive oil clearance and the engine will need major work.

Lol. Good analysis .


I have seen plenty of GM's blow an oil pressure switch though!

The car is a 1999 Chrysler Cirrus, with only 103 000km on it. Oil changes etc. every 5000km as per the manual. The only thing I don't do often enough to it is to wash it.

First things first. Check the oil level.

Use a mechanical oil pressure guage. See if the oil pressure is actually low.

I have checked the oil level numerous times, and it is fine.

Never seen a mechanical oil pressure gauge before, but I will look into it and try that.

auto-zone can probably rent you one, not expensive.

Autozone rents them free of charge.

Measure the oil pressure with a gauge comparing it to the shop manual's specs. If it's ok, you have a bad oil pressure switch.

If the pressure's out of range, internal engine problems are likely.
