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?
