Wow man. Its DEF or diesel exhaust fluid. Urea for short. No oil

[compoundridersinc]

These trucks hold 5 gallons of Diesel Exhaust Fluid which is urea as someone said. It injects it into the exhaust system post DPF to cut the NoX emissions. It uses about a gallon per 1000 miles. You can buy it most auto parts stores and truck stops for about $3-5 a gallon.

It's urea. It's used to burn the black soot that builds up in the filter that keeps the black smoke from entering the air that is causing damage to our ecosystem that requires more fuel to run truck that in turn costs more money that causes the oil companies to manufacturer more oil that allows government to start funding corn based fuels that causes food shortages in third worlds that causes govt to spend more money that raises our taxes that pisses us off and makes us lose our mind and write crazy run on sentences!!
Seriously, I understand making things cleaner for the environment, but can someone explain to me how burning more fuel and "UREA" equates to being better than less fuel and carbon??

schillster, do a Google on DEF and learn enough to not make ridiculous statements.

I stand corrected if this is the exact way urea is used in the 11's.
"The newest, approach is selective catalytic reduction using urea DEF. The urea-based solution (32.5 percent industrial urea and 67.5 percent deionized water) is held in a separate storage tank and injected as a fine mist into the hot exhaust gases. The heat turns the urea into ammonia that - when combined with a special catalytic converter - breaks down the NOx into harmless nitrogen gas and water vapor."

However, if I understand it correctly, in order to burn this, the truck has to burn more fuel to create this process? AM I WRONG,,, CHEROKEE?!?!!? This is the reason these trucks are still getting less mileage than they should!?!?! Isn't this why owners still delete the DPF and get a tune???? To get better mileage??? So, maybe I was slightly off on my statement, "urea is used to burn the black soot" when it should have said, "it's injected as a fine mist into the hot exhaust gases, that get hot by increasing the trucks RPM's by burning more fuel, but who knows,,, maybe I'm still wrong!! PLEASE CLARIFY!!!! There's no need to be rude ,, CHEROKEE!!!
If I'm still wrong, help me out.
