Damit Tracy, don't get me started thinking about this :-)  Has anyone tried using one of these for oil yet?  Certainly the pressure should be OK.  Arrrrrgh...

I am using one for an oil cooler, mounted up in the nose cowl. I have not yet flown, but cooled great on ground run ups. Never went over 180 in the pan even when water temp went to 230.
