This is important to consider when storing DEF on your farm, as containers shouldn't be filled so full that they burst when DEF freezes and expands. And though DEF is basically a non-toxic, non-flammable and non-hazardous material, it does have a limited shelf life depending on conditions (the gel point is 14 degrees F and the ingredients will start to separate at temperatures above 112 degrees F). While you might be thinking we should worry about the large polluters trucks and busses etcetera the facts are that 47 percent of diesel particulate matter (PM) and 25 percent of total nitrogen oxides (NOx) originate from nonroad equipment.

Maybe somebody has more definitive info on just when the various ISB engines changed over. Used in systems with SCR (Selective Catalytic Reduction) which is an alternate to EGR for reducing NOx. The main advantage of using DEF is that engines run cooler since they can meet emissions standards with less aggressive use of exhaust gas recirculation (EGR). That being said they may have been left over 2013 models, it made no difference to me I did not want the added garbage. By using DEF and Diesel Oxygen Catalyst, they can run hotter combustion temperatures which results in high NOX, but they take care of that with the DOC and urea in the DEF to convert the NOX.
