Larry you are correct, you normally want to keep the oil temp above 180F. You do not need 212F to remove water from the oil. Rapid evaporation will occur at lower temperatures. The 180F you hear refered to as the limit is the perferred maximum rotary oil temperature AFTER its has been through the oil cooler and before it goes into the engine again. So the oil temp is undoubtedly higher before it goes into the oil cooler - perhaps as much as 220-240F. Ed Anderson
