In short, the higher the delta T, the better.

BTW, this is a major argument *against* oil/water heat transfer

systems: the oil

radiator has a *much* higher delta T than the water radiator even with

the oil's

heat added to the water.

Russell,

  As I recall from discussing this with Fred Moreno, the lower delta T is
more than offset by the fact that the oil/water cooler transfers heat much
more effectively than a conventional air/oil cooler. That is for a given
amount of heat transfer area (core size) the oil/water core will transfer
much more heat than the oil/air cooler. Unfortunately I cant locate the
email he sent me which gives hard numbers that show this.
