    Oil Light Keeps Coming On

    I filled it with Mobil 1 synthetic oil about 1000 miles ago. The light has been coming on intermittently the past couple of weeks. I checked it it wasn't all that low, but I added more. Light still keeps coming on once in a while. Today it came on at start, drove it for an hour. Started it back up and the light was gone. WTF? I know the oil level is fine, what can be triggering it?

    You may have a bad oil pressure sender. There easy to change, its right above the oil filter, in front of the oil filter housing.

    Thanks. I found this thread too:

    Whats the actual part name? Napa lists it as a Oil Pressure Light Switch, I think.

    If you went to a much lighter oil, a 0 or 5w whereas you were using heavier before, it could have caused the problem. I say that since you mention it happened after the change. But the sensor will also go bad, mine did, it would sporadically, sometimes yes other times no, just show the pressure dropping while I was driving. Sending unit ended the problem. It is by the filter or on the other side of the engine from the filter, usually.

    Likely cause is the sensor or the wiring/connection to the sensor.

    If your engine was sludged up some, the synthetic oil (if this was a first time use) could have dislodged a lot of stuff to be caught by your filter. What filter are you using?

    Here's how the system works. http://www.filtercouncil.org/techdata/tsbs/83-1R2.pdf The pressure sensor is beyond the filter. Might consider changing the filter.

    It was a MOPAR filter.

    I would replace the pressure sensor. It is located right above the oil filter. I believe it only cost me between 10 and 20 canadian dollars at the dealership. Replacing it solved my oil light problem. Read your trouble codes, mine set one I forget the code though.

    If you want to be sure, for free, you can likely borrow (pay for and bring back for refund) an oil pressure gauge at Autozone or other parts house. Remove your unit, put it in and run the engine to see what the pressure it. One caution, some of these units are an aluminum housing and wring off in the hole if you overtighten. The last ones I did are a taper fit pipe fitting so they gradually get less thread and tighten on themselves. Not sure on the Chrysler. Did that on my Simca. You can rent a sending unit removal socket at the same store. Might as well buy the unit too, and return it if it is not needed. Hankster and Jeepman have good points. If your new super oil broke loose or dissolved a lot of goop, it could be clogging the oil filter, but if so, do your lifters clatter when the light comes on? If not it may well be the unit (Unless the lifters are now full of junk too).

    The lower number doesn't matter. What matters is the higher number. You can use any oil that has a hot viscosity of 30. Now straight SAE30w will drastically reduce fuel economy when cold, but will be no different when hot.

    But yes, the sensor is probably the issue. I've seen one go bad instantly once. I was under the car with the engine running and it had no leaks but suddenly oil came blowing out of it. Although this was on a GM 3.4 engine and those were pretty terrible all around. Seems to happen often on any type of vehicle.

    I have had to replace my sending unit on a couple of vehicles. Yes, they can cause the problem you are describing. Yes, they are easy to replace. Also consider getting one of the "big filters", not the little ones. The big ones provide better overall flow, as well as more filtering surface. Just make sure they have the anti-flow back valve in them. SEARCH this forum for "oil filter" and you'll find the recommended models.
