Thanks pee wee, I remember that... now.

just pee in it.....it's the same thing !

Hi. just my 2 cents, we might be better off with a SCR system.
There is some issues comeing to light with Regen useing rich fuel injection
causeing lube-oil dilution. Charley

if i ever get my hands on one, i will let you know...

urea? as in pee pellets?? guess i better do some research....

I really want to know if these emissions controls will incorporate urea pellets in an exhaust catalyst device. Most other bluetec and clean diesel manufacturers in 2010 will have some variation of this which will require periodic replacement of the urea pellets. I'm not too keen on having a exhaust restrictions on a turbocharged engine. Especially if they require replacement at 12,000 mile intervals from what I've heard.

Does anyone know if this will be the case?

Yes, but in polite society we call it DEF, Diesel Exhaust Fluid.
Probably for the same reason we say canola oil instead of rapeseed oil.

"Diesel Exhaust Fluid"...
What's next <real> "Chrome Muffler Bearings" and "Ramastat Injection Pinions"?

What happens if you continue to operate the vehicle when the urea tank runs out?

I know GM has a "limp" mode that limits one to 5-10 mph to get to safety, this is only after about a gillion warning lights telling you 1000 miles before it runs dry.

From the Facts About Scr Site

Diesel Exhaust Fluid is subject to freezing at the lowest temperatures. For example, Diesel Exhaust Fluid (made up of a 32.5% urea solution) may freeze at temperatures at or below 12° F. Although this temperature is encountered in colder climates during the winter season, it has not proven to be a problem for SCR-equipped trucks. Freezing does not impact its functionality and Diesel Exhaust Fluid is easily thawed within moments by the warmth of the engine.

Some automotive-grade urea producers are working on non-freezing additives and technologies. In the meantime, equipment systems are being developed and will be used to ensure that Diesel Exhaust Fluid thaws quickly. In fact, the EPA sees no problem in allowing it to reheat in the morning using the warmth of the engine when the truck is started.

This sounds good, and I've been wondering about how these new smaller diesels will do in the cold. Does anyone know if these have glow-plugs or other strategies for starting in the cold? While I have a heated garage at home, here in northern MN my vehicle often has to spend 8-10 hrs in sub-zero temps throughout the day.

I keep reading about these Indian Scorpios with the 2.2 liter engine that weigh over 1000 pounds more then the TR's, have a 5 speed manual, and get 22 mpg city and 29 highway. Will all of this urea kill the fuel efficiency or can we expect 25 mpg city and 31 highway?
