Obviously, this is for us Diesel Car/Truck Owners. Some 2008 - newer Diesel Vehicles require Diesel Exhaust Fluid be injected into the Exhaust to lower NoX Values.
It turns NoX into harmless water or Steam. Here is the Story from the Mercedes Benz Dealership:
Mercedes-Benz Genuine AdBlue is composed of urea and de-ionised water. It is injected into the exhaust gasses of selected diesel engines as a post combustion process. Mercedes-Benz vehicles using AdBlue® technology are identified with the ‘BlueTEC’ symbol. AdBlue’s® purpose is to reduce the percentage of harmful NOx (Nitrogen Oxide) found in the vehicle’s emissions. With BlueTEC technology, Mercedes-Benz has been able to heavily reduce exhaust gas emissions while at the same time maintaining the performance of diesel engines in terms of power and torque output.
There you have it. The same is true for VW's, BMW's, Porsches (Yes, they make Diesels too) and many other American or Asian Diesels.
On my Car, for example, I get a warning in my Dash that my DEF is low and I'll have 25 more startups.
If I haven't filled the Tank by then, the Vehicle will refuse to start.
Alright, my DEF Tank holds some 7 Gallons of that nasty Stuff, the (S)Dealer wants about $20-$30 per Gallon to fill her up. YMMV, ok? That's Crazy!!!
Perhaps, Volkswagen only charges ...what $18-$22/Gallon?
I decided to do it myself. Walmart has the 2.5 Gallon Container for less than $12.00. That is $4.80/Gallon.
Even a Monkey can re-fill his own DEF, no need to go to the Dealer.
My DEF Tank is in the Trunk, under the Cover. You can see that 6 Inch round hole that contains the cover, we need to un-screw it and get to the Tank .
In your Vehicle, there might not be a Cover, maybe just a lid.
Look at your Manual to find out exactly how to find it.
Here is a better look at it.
And simply start filing that Tank. I don't know how much I used, I'll start with the first Canister.
Conveniently, that Canister comes with a nice Hose to insert it into the Tank.
Slowly fill it, make sure you do not EVER EVER spill it on your Interior.
It will stain the [email protected] out of your Interior. Luckily, in my Case there is no Carpet anywhere near the opening.
I stuffed a bunch of Rags in there to make darn sure I won't spill anything.
Better safe than sorry.
Here is what the Box looks like from Walmart:
Get it at Walmart, it is the same thing the dealer sells you. Trust me on this one.
Today I only used 5 Gallons of the Stuff.
My Cost: 'bout $25.00
My Time: 15 minutes
Dealer Charge for same amount: $150.00 more or less.
A no Brainer.
