OK, aside from the "cottonseed oil will kill you and should never be used in food prep" argument, what is the consensus on which oil is best for feeding my TDI? I know canola is supposed to be the best, but I get 3-4 cubies a week of very clean cottonseed/canola blend augmented by a few cubies a month of well-used soybean salad oil from a chinese place.

Anybody ever see/do any kind of actual testing to evaluate the use of different oil in a diesel engine?
