dont forget to change you exhaust fluid!
so, i get a text saying that the new duramax trucks have exhaust fluid and cannot run without it...i chuckled at the joke, until i get this text next
can someone in the know fill us in? i can imagine how many husbands come to dealerships pissed off because some tech told their wife to change the exhaust fluid

I had to search but thought I'd remembered about some fluid in the exhaust system to reduce NOX emissions.

Yep, it's on all the new diesels coming out. It's supposed to reduce their emissions by a whole lot.
Talked to some Ford techs and evidently if you let that fluid get too low, it will shut the truck off until you refill it. Sounds pretty lame IMO.

dont joke. it will be next lol. something to control global warming and the headlight fluid reduces the heat a conventional light bulb produces.
there, i gave everyone a trillion dollar idea! run with it and dont forget who came up with the idea when you are rich as forrest gump.

I saw title & had to read it. I've seen & heard it all now. 
That said, anybody every heard of a prodsponder? For y'all to check out if not. If this isn't you, go to :52 sec & listen, at 1:05 is what I mean.

yeah it's urea, and like Scott said if you run low it goes to a limp mode that only moves the truck 5mph (essentially idle). Urea reacts with diesel emissions to reduce NOX levels, like KySilverado said.

we have the same fluid in all the new diesel mercedes benz at my work. its sprayed into the exhaust to reduce nox.
Used in conjunction with a Selective Catalytic Reduction (SCR) converter, AdBlue has a profound effect on otherwise difficult to control oxides of nitrogen (NOx) diesel emissions. On average, NOx emissions are reduced on the order of approximately 80 percent. The AdBlue solution is comprised of 32.5 percent high purity urea diluted in distilled water and carried onboard the diesel vehicle in a special independent tank. Under the direction of the onboard computer and an NOx sensor, the fluid is pumped into the exhaust stream at the rate of 2 to 4 ounces to a gallon of ultra low sulfur diesel fuel (ULSD) consumed. And it is here, in the hot exhaust stack, where the urea solution is converted into ammonia (NH3) which reacts with NOx in the exhaust. The resulting chemical break down and re-bonding of the constituent elements of each reactant produces plain nitrogen and water vapor.
We already have had problems with the adblue tanks and sensors going bad. Just another thing to fail on new diesel vehicles.
