Where does DEF fluid get injected?
Small quantities of diesel exhaust fluid (DEF) are injected into the exhaust upstream of a catalyst, where it vaporizes and decomposes to form ammonia and carbon dioxide. The ammonia (NH3) is the desired product which in conjunction to the SCR catalyst, converts the NOx to harmless nitrogen (N2) and water (H2O).
How much Def fluid is left in 2012 Duramax?

What’s the best way to store Def Duramax?
It is best stored out of direct sunlight between 12oF and 86oF.” A full tank of DEF provides a driving range of about 5,000 miles (8,000 kilometers).” The DEF is held in a 5.3 gallon tank under the hood in an uninsulated container. Do you think that the DEF stays under the recommended 86 degrees F ?
Why is my 2012 LML Duramax Def blue?
Typically its an NOx or EGT sensor starting to go funny that will set the poor def quality message. It happened to both of ours. One is a 2011 2500HD and the other is a 2013 2500HD. a ton of codes, so a reprogram and DEF tanks for both. DEF is always new DEF Blue like everyone else uses.

What does speed limited on GMC Duramax mean?
200 miles down the road the “Speed Lmited to 55 mph at next Restart” message shows up. WTF, now I am pissed. I pull over, add DEF while running, and call a dealership 20 miles down road. I pull in to a parking lot next to dealer, shut truck off and unhook trailer. Start truck and get svc def and speed limited message.
How many miles per gallon does a LML diesel get?
if 100 gallons goes 15 x 100 = 1500 miles, then 1500 miles/1.5gallons def = 1000 miles per gallon of def. if it gets 20 and only uses 1.25 def per 100, then 2000 miles/1.25gal def = 1600. Between 1200 and 1500 mpg seems to be the most commonly reported range for the LML.
