NuDEF tackles the #1 cause of DEF system failure, and more
DEF crystallization & DEF crystal deposits
Over time DEF can crystallize within the tank, lines, pump and injectors. These DEF crystal deposits block the flow of DEF and can even lead to premature failure of DEF system components. Prevent costly repairs with regular use of NuDEF.
NuDEF’s triple-action formula is the world’s first DEF treatment and stabilizer designed to help fix, maintain, and prevent issues with your truck’s DEF system.
Extreme weather
High and low temperatures also take their toll on DEF system components.
Extreme heat can accelerate the crystallization of DEF while extremely cold temperatures can cause DEF to freeze solid and potentially damage DEF system parts.
NuDEF combats temperature related DEF issues by preventing DEF from evaporating quickly and lowering the freezing point of DEF.
Wear and tear
DEF crystal blockages and extreme weather create unnecessary wear and tear on your DEF system. DEF pumps need to work harder in order to keep the DEF flowing while lines and injectors can clog up and stop the flow of DEF completely.
Regular use of NuDEF not only keeps all system components clean, it also lubricates delicate parts.

I had a yellow engine light appear on my truck, looked up the code on the ODBII scanner and it was related to the DEF, so I searched online and heard about this stuff. I followed the instructions, put the correct amount in my DEF tank and when I drove the truck again the error code was gone and has not come back (I did this a couple of months ago). From now on I'll add some whenever I add DEF.
