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
What I believe he means is that pre-DEF Diesels that had DPF’s used massive amounts of EGR to control the combustion temperature. EGR works, but it sure comes at a heavy price in added problems and reduced reliability. I’ll be glad when EGR goes away entirely.
