The urea injection itself causes absolutely no power loss.

Sure, but I'm still not favorable to that because it adds some weight and increases the running cost. Seems to be a way to kill the savings from the use of the diesel engine :facepalm:

Considering most big rigs get 4 - 5 mpg loaded, the pollution reduction is worth the 100kg's it probably adds

But into a Dodge Ram or a Silverado I'd rather not have this setup. Another fuel tank to get an extended range seems more attractive to me.

But if you can reduce pollution with no measurable difference in performance, why not?

Whether you are favorable to it or not, it is here to stay.

Sure, it costs more, adds weight and maintenance.

There is nothing we can do about it.

It is on every 2010 model year truck except the Navistar products, and their carbon credits from the class 6 product are rumored to expire sometime this year.

There are no mods around SCR for heavy duty product. Maybe for the owner/operator. I have had to deal with a few owners that have tried to defeat the EGR and DPFs on their 2 truck fleets, but larger fleets will not even try.

It is here to stay.

The only I've heard so far about the SCR is the urea starting to freeze up, other than that I am unaware of any other major issues, maintenance wise...
