I overheard some farmers talking at a local tavern about how good this oil is in colder weather. I even heard them rumor about this oil flowing even better then some 5w40 synthetics. I initially assumed they knew not what they were talking about...until I looked at the pour point specs online yesterday. I was shocked to see the very low pourpoint for this dino oil. I looked at some specs online of some readily available synthetic 5w40's, and YES this JD 15w40 dino had a lower pour point! I do not remember the specs off the top of my head exactly...but I know it was lower than the 5w40's I checked. I know that physical characteristics of an oil mean nothing in regards to a UOA, or even engine wear sometimes...but my question is what makes this dino oil flow so well as advertised? Could this be some kind of "synthetic blend" by chance? Supposed to be a great all around oil I have heard also by the way!
