So all I'm saying is, copper is probably ok IF you have good oil.

They posted a report on Frybrid's forums about how veggie oil polymerizes in a bunch of different environments. One of the conclusions is that copper in contact with VO leads more quickly to polymerization than SS, with aluminum being the least reactive. Heat is also a factor. I dunno, haven't done any experiments myself, just re-stating what's in that report. If you're having good luck, keep doing whatever you're doing.
Here's the thread with the report, and you can read all the different arguments people have interpreting it: http://www.frybrid.com/forum/showthread.php?t=6510

Actually a tranny works best if the tranny fluid is above 150 degrees but not too hot so the hot coolant speeds up the heating of the tranny fluid and still prevents it from getting too hot.

I use hose in hose on the supply and return.
Aluminum refrigeration tubing 5/16 cheap ($20 /50 feet) at the local hvac supply. I loop my return at the tank so the oil gets heated in two directions and then a final blast of heat from a small heat exchanger before the injection pump. No problem getting to 160 degrees. The key for my setup is the looped return at the tank giving 24 feet of hose in hose loop to heat the oil. Steve
