Keith Lucy,

How full does the dipstick measure when the light comes on? Also, it sounds like the temperature sensor is working about right. Ten to twenty minutes, depending on the ambient temperature and driving conditions is about right to get the oil up to 80 degrees C or so. Unless the dipstick is showing the level is substantially over the half way point between full and low (closer to full), I think the sensor is working about right, too. In any case it seems to be funcioning, possibly not set at the level corresponding to the midpoint on the dipstick though. You may see if there is a way to reset the level at which it turns the dash light on before replacing the entire sensor. Good luck, Jim
