So I found out that my oil pressure gauge is actually just a dummy gauge. grr! There's not actually a oil pressure sensor, there's only an oil pressure switch that triggers the gauge if the oil pressure is excessively low--otherwise the gauge just reads a estimated oil pressure (which I'm guessing is based on engine speed and coolant temperature). C'mon Chrysler! Really?!

So my assumption that my oil pressure gauge was an indication of how my oil pan heaters were working was incorrect.


So I'm working on actually measuring the coolant and oil times (vs. time plugged in). I'll post more when I get more data.
