For the duratran line, the syn blend is a winter only tractor fluid so be careful just assuming its going to be better than their regular fluid. The duratran full synthetic is for year round, but still falls short of the regular duratran in the shearing tests, flash point. The regular duratran still has pretty decent cold flow, better than the Chevron THF1000 I was using before and I try not to start my tractor below -10C which is a pretty reasonable temp for any conventional fluids.
