So we both agree that monitoring oil temps is a good idea.  :-)

Would severely sludged water jackets contribute to higher oil temps in WBX? Just curious.

You don't really need a gauge to show that, given the  mileage and the fact that changing to lighter oil viscosity caused the warning system to be MORE active...
