So, I was just informed yesterday that the newer trucks have exhaust fluid. Did you guys know this?
Stupid government sticks it to us again. Higher EPA standards = more money out of everyone's pockets. On top of that vehicle emissions is NOT the number one contributor to pollution. But try and tell big money that.

Anyhow, here's one thread I found regarding it...
Explain the urea exhaust fluid! - Page 7 - Ford Powerstroke Diesel Forum

 

Yea I seen that stuff even the newer big trucks require that stuff...I dont know how long it lasts. At some truck stops they have that stuff at the pumps so when you fill up on fuel, you can fill up on that fluid.

 

I wouldn't be too upset about it.

Vehicles have a lot of fluids. This is just 1 more. Just like adding wiper fluid.

I love my 7.3 but the 6.7 is such a clean motor.

 

I believe it has to be filled at every oil change from what I've read. Not a big deal, but one more reason why I love my 7.3.

 

I know a local guy that has 2 of the new PSDs, and yes, it is meant to be filled along with every oil change. It holds either a 3 or 5 gallon tank. Look at it this way, since they are using this new technology to clean the emissions, you don't have to worry about the regen cycle anymore that plagued so many people at just the wrong time.

 

Buddy of mine just got the new Chevy and it has the 5 gallon tank for urea. Not sure if he can fill it himself if it get low! ! !

 

The new diesels still have DPF's and therefore still require regeneration of the filter. The DEF has a limited shelf life so you can't really stock up on it for extended periods although the actual shelf life at room temp is bound to be determined.

 

As others have mentioned, Diesel Exhaust Fluid or DEF is a fluid that is filled in a seperate tank. The fluid is sprayed directly into the exhaust fluid.

It doses at a rate of around 2% to a gallon of diesel.

The advantages are improved fuel economy as well as near 0 nox out the tail pipe. The alturnative it to deal with the nox in the engine and this creates higher engine temps and pressure.

I am the the DEF business, but can provide further information as requested.

 

Hi Rustin

 

i think shelf life is like a year in optimum temps. and the def is used as a mixture in the dpf.

 

thank god for my "old" truck!!

 

No kidding... Thank God for my 7.3!

With that said, just like my info at the bottom says I bought the wife a 2010 VW Toureg TDI. It uses the same liquid to help clean up the exhaust. That thing doesn't smell like a diesel at all and the only time that you can tell it's a diesel is when you really get on the go pedal and the turbo whines a little bit.

According to the manual there is a light that comes on when it starts to get low and the owner can fill it themselves. Just dump the bottle into the filler neck and then you're good to go until the next time.

 

DEF has been in place in Europe since 2006. It is 2/3 water and 1/3 urea. It does an amazing job of reducing pollutants in the exhaust and the cost is generally much less than if one were to go to more EGR which would add considerable cost to the engine and cooling system to product comparable horsepower. It is already widely available in the U.S.

One thing ford did was put the DEF filler neck right next to where you fill up with diesel but Chevy put theres under the hood, kind of a pain to me. Pilot stations have a pump right next to the diesel pump and its about 2.99 a gal but if the pump is out of order you can go inside the store and purchase the DEF in 1 gal jugs and it will cost you $15 a gal, not sure how that works but someone is getting payed. The truck still go's into regen mode as the DEF is only to reduce Nox it dosent clean the DPF.

x2.. lol.. My thoughts exactly.
