ONLINE SPECIAL: Early spring increases urea demand, drives up DEF prices

Trucks that use DEF are a pain in the tuchus if you ask me. Surely the truck manufacturing industry, with all their brain power, can come up with a better way to reduce diesel exhaust without a system that practically cripples a truck if the DEF is contaminated or if you don't keep it replenished. Like a heavy duty exhaust filter that you change every so often or some other system that safely gets rid of most of the carbon before it leaves the stack. There's never going to be zero emissions and DEF is not really an efficient solution. One driver had problems with DEF so bad that he had to visit Volvo dealerships the whole way home and not one could find the problem - and he was coming from Indiana. One place said there was contamination, another place couldn't find the problem, and yet another Volvo dealership said it was something else. And it was a brand new Volvo that always had 2 new fresh jugs of DEF in the compartment, with levels always full. The downtime, added expense of DEF and inability of the dealerships to accurately diagnose their own product's diesel exhaust system is not a testament to "green" trucking.
