Blue Tec Fluid
I've heard that all 2013 diesels require the blue tec fluid. How much cost does that add to your driving. Also how many gallons of diesel does one gal of the stuff treat? Thanks in advance

They require Diesel Emission Fluid aka DEF which is 30% Urea. One company has branded their stuff: BlueDEF but I never noticed that it was blue, and it is the most expensive. It does come in a blue box. And lastly it is no different than the generic DEF like Walmart's or the stuff sold at some truck stops.
Buying the cheap stuff costs $6-7/2.5 gallons and will last thousands of miles. The extra cost is minimal, a few cents a mile. Worth it to reduce NOx emissions which are a major contributer to smog.
From my perspective what makes it worth it is that DEF treats the majority of NOx chemically rather than mechanically by punting to under hood emissions components, thereby reducing engine soot.
