Sourced an Audi Oil Cooler

[brian_wagner at sbcglobal.net (Brian Wagner)]

Oil Temps (per a Regional VWoA service rep and Scirocco owner that runs in a Tropical Climate (TX)) can be between 120C and 140C and not effect the life of the engine.
 
And was or is not uncommon to run 135C with a/c on in stop and go traffic.

In my case running a 3a/jh 10.5:1 Compression engine @ 120'F using AC =
120-130'c on the oil
This is why I did this mod.


Okay. That's cool. I'm not trying to start anything. Like I said, I was
in regular 100+ heat and stop-n-go traffic without issues. If you're seeing
higher temps, I can appreciate that you'd want to do something about it. It
seems that some people have tried hard to keep oil temps so low, that
they're running under 100'C. I had learned that you want to keep oil above
100'C to boil off condensation and limit parasitic drag from thick, colder
oil. You guys aren't seeing those kinds of temps, so it's a non-issue.
