Well I for one have run AT LEAST a couple gallons on my K5.9 in cold weather under 40F.
It's on 11+ gallons now and people around RCU insist that the 5.9 is junk to begin with, so how did my 5.9 survive 2 years running in the snow and cold and this summer it was still capable of doing this-




My guess is that I know how to tune...
