Intermittent oil light

Intermittent oil light

My wife's 2000 Chrysler Cirrus oil light came on recently. It came on
when she stopped the car in the driveway. Later, I drove it and it
came on a few times when I would come to a stop sign or a traffic
light. As soon as the RPM's were raised, it went off. Afterwards, it
didn't come on again. I checked the oil and it is in the full range.
I'm assuming, and I hate to do that, the sensor may be going bad.
However, if it was, wouldn't the light come on at the same RPMs each
time.
It hasn't come on lately. Any ideas.

Re: Intermittent oil light


Oil pressure depends on engine speed, the thickness of the oil, and how worn the engine is, especially the bearings. Oil thins out a lot as it heats up. If the light comes on only when the engine is warmed up the problem is probably low oil pressure, and not a bad sensor. You can increase oil pressure by using a higher viscosity oil. Many people have used 20W50 oil, even in cold weather, but you should be aware that it becomes quite thick when cold and may not circulate properly to some parts of the engine.
