How accurate do you think the
oil temperature sensor is, especially in cold weather? The reason I ask is that my
oil temp characteristics are pretty consistent with what was written above. However, one additional observation: on cool days especially, for example, when my gauge reads 70 degrees and I come to a stop sign, the gauge quickly (within a minute or two) runs up to 80 degrees; if I turn off the car it goes even higher. When I start driving again it will go down to 70 very quickly, on cold days down to 60; all within seconds/minutes. Can the temperature of your entire
oil system really change that quickly? Or is it that some parts of your system, or just the air flow on and around the temperature sensor are causing your gauge to move around?
