Re: questions about diesel exhaust fluid ?
It's more EPA meddling, forcing the automakers to conform to almost unattainable emissions and mileage gains. I am a huge diesel fan; I own an 06 2500HD Duramax and a 2011 VW Toureg. They both have great engines, the Chevy has no emissions equipment and the Toureg has the particulate filter and urea injection. The Toureg's exhaust has nary a trace of soot, and very light odor... but then again my Duramax has very low soot compared to other makes and models. You only get black smoke if you floor it. Does the technology work? Yeah I guess so, but at what point are we spending so much money and putting so much crap onto these engines that we are just creating more problems. My VW is supposed to go 10000 miles on a tank of urea. The engine will lockout if you run out. Guess what happened the other day? I got a false low urea warning after only 2000 miles. What if the tank quantity sensor fails? You are stuck. We should be focused on bringing more diesels into the market. The diesel energy cycle is up to 30% more efficient than the gasoline Otto cycle. Why America has resisted cheap efficient diesel is beyond me. Instead we adopted low sulfur diesel, which is a horrible fuel blend with low lubricity that costs oodles more to produce. Go figure.
