Al, I don't know about lowering coolant temps affect on oil temp.  However, I can tell you that when I lowered my oil temp by approx 30 deg F my coolant went temp went down 15F.

Subject: [FlyRotary] Cooling coupling

I’m curious how much thermal ‘coupling’ there is between the oil and water cooling in the engine; and whether it is more one way than the other.  IOW; if I could lower the coolant temp by 20 degrees, how much effect would that have on the oil temp, if any; and vice versa.

 

I’m thinking about this regarding cooling on the ground, and if I’m going to work on reducing one or the other, which might have the greater benefit.  As it is now, the oil gets to 220F about the time the coolant gets to 210F.  Options under consideration are a fan behind the coolant rad; and a water spray setup for the oil cooler.
