And just think, you have to use all of this DEF just to save a very tiny .01 g/km versus older trucks that didn't use it. I wonder if that .01 g/km is worth the added pollution from the jugs and chemical plants used to make DEF. Probably not. Heck, even our older trucks without DEF and EGR's had a lower NOx limits than even the latest Euro emissions standards.
One would think that their mortality rate would be lower if NOx is as bad as the EPA says it is in the US given that the Euro emissions have been a lot higher than ours for decades and they have many times more diesels on the road than the US. However, our mortality rate is near the bottom versus most European countries because it is acceptable by the government to eat 10 cheeseburgers a week, but how dare you release an added .01 g/kw of NOx even though other countries are much higher without issues.
