My understanding is that the oil temp should be kept well into the green to insure the water from the combustion process is evaporated out of the oil. I close off the oil cooler a bit in cruise to insure this.

As a sidebar conversation, I was taught to keep oil temp at 180 in flight through slight adjustment of the oil door.  Typically at level off in low 20's have to close the door a bit to do this.  

I think the theory behind this is to keep a constant oil pressure (48-49 psi in TSIO-550) through constant temperature.

Is this common, or an old wives tale?
