Car Info : Automatic, 88k miles, 2.0L engine with no modifications.
Problem : Oil warning light started coming on this morning on the way into work whenever RPMs dip below 1000. As soon as RPMs hit 1000 or more, light goes out. It's 12 degrees outside here in Michigan, and I'm running 10w30 mobil 1 synthetic.
It's been suggested this is a problem with the sending unit for the oil warning light, but I don't think that's accurate. There are no funny noises coming from the engine. I checked the oil when I got to work, and it looks a bit dirty but the level is right between max and min. If this is an oil pressure issue due to the oil viscosity thickening from the temperature, why would that start happening when the engine warmed up? It was about the time that the engine was in its normal operating temperature that this behavior began this morning.
Any ideas would be appreciated.
