The urea schit will keep me from ever buying a new diesel anything.
I don't want emissions crap on mine, but urea isn't a bad thing. Diesels are big in European sedans and for years they've had urea systems. Dodge/Cummins didn't have urea and had to pass emissions by going into the tuning map, that's why they were down on power compared to the others. Urea cleans the exhaust after it's left the engine and he tune can be left where it should be for power. It's a good thing. But nobody's forcing anyone to like it.
