On top of that the oil temp has either been "dumbed down" or the sensor is mounted in the oil cooler loop and it takes forever to see that actual temperature. There's no way it's taking the oil in this engine that long to come up to temperature.
If this is true, wouldn't the car be running pretty inefficiently since the computer is using the same temperature to use in its calculations? Also, if it's delayed, then when the temperature reads 230* it could actually be at 280* or some high number because the water pump wouldn't be trying to cool down the engine very fast even though it might be over heating, right?

On my drive home from work today, it took 10 minutes to get to about 180*F, and finally plateaued around 235* after a total of about 20-25 minutes.

It just seems like there's a big difference between 235* and 180*...
