Doug,

Good timing as I just flew yesterday in 90+ temps and high humidity.  First,
I need to explain my oil flow circuit.  Oil exits the engine, passes through
the filter and enters the oil/air exchanger.  Oil exits the oil/air
exchanger and enters the oil/water exchanger and finally back to the
engine.  I measure oil temps out of the oil/air exchanger and also out of
the oil/water exchanger.  On yesterday's flight, in climb, temps got up to
223* out of the first cooler and 205* out of the second.   They come down
about 20* as soon as I level off.

I don't recall what the  water temps were, but they usually run about 10*
less (in climb) than the oil.  All in all, I am very happy with my temps.

Mark
