![]() You’ll experience better fuel economy and increased power. Since emissions are regulated, and you’re required to meet certain standards, you may as well choose the CSR/DEF vehicle. A CSR/DEF vehicle gets poor gas mileage: FALSEįact: A DEF vehicle gets similar fuel mileage as those with other emissions-reducing technologies. Interestingly, at that temperature, it would take over two years to reach the ammonia levels of household ammonia. Even at high temperatures (which are avoided by the cooling and temperature stabilizing design of DEF engines), DEF will still meet ISO specifications of less than 0. The chemical makeup of DEF is not affected by freezing and thawing. DEF is unstable: FALSEįact: Urea does not become toxic at any temperature. Depending on how much you’re hauling, the rate of DEF use is about 2.5 gallons for 800 or so miles of travel – that’s a refill of about five to 10 times per year. You don’t need to refill your DEF supply every time you fill your gas tank. Filling the DEF tank is as easy and as accessible as topping off your windshield wiper fluid. DEF is hard to use: FALSEįact: DEF is a readily available liquid from larger, commercial filling stations, or off the shelf at vehicle parts and lubricant suppliers. ![]() Human urine contains very little urea in comparison. DEF is a combination of 32.5 percent urea and 67.5 percent de-ionized water. ![]() The automotive-grade urea used to manufacture DEF meets the strict production and emissions standards of the American Petroleum Institute.ĭEF uses a much purer, particulate-free urea than the agricultural applications require. Since the 1930s, synthetic urea has been produced by synthesizing synthetic ammonia and carbon dioxide in a heated, sealed process. DEF is urine: FALSEįact: Has someone told you urea is animal urine? Or equivalent to human urine? Not so much. From an environmental (and safe working conditions) standpoint, this is preferable to NOx which is the cause of acid rain, smog and the rise in greenhouse gas levels. The result the NOx and DEF combine to form harmless nitrogen and water – naturally occurring elements in the fresh air we breathe. The kind used for auto grade-level products is even more non-toxic than agricultural grade.ĭEF is less toxic than most of the other fluids in your truck, including diesel fuel, engine oil, brake fluid, antifreeze, and windshield washing fluid.ĭEF is injected into your vehicle’s exhaust stream, reacting with the Nitrous Oxide (NOx) in the SCR catalyst. Over 90 percent of the world’s urea is allocated for agricultural use. It’s readily absorbed by plants, promoting significant growth. DEF is made from urea, a high nitrogen compound most frequently used for fertilizer. For comparison’s sake, water has a pH of 7.0. It has a natural pH of 9.0 – about the same as common household baking soda. ![]() It requires no special handling and is not polluting. DEF is toxic: FALSEįact: DEF is a non-toxic, non-hazardous, and non-flammable fluid. We’ve put together a list of the most common myths about DEF so you can be armed with the facts. We at NEXGEN DEF want to help set the record straight on DEF. That’s just another one of the pesky myths about DEF that still pervades today. If that wasn’t impressive enough, DEF is a non-hazardous, watery solution made up of 32.5 percent urea and 67.5 de-ionized water. Added to engines with Selective Catalyst Reduction (SCR) technology, DEF will reduce NOx and particulate matter by 90 percent – a significantly low emission level near zero. Its development and use were a significant step forward in the reduction of greenhouse gas emissions. DEF is an additive required by many diesel engines. There is much misinformation floating around about Diesel Exhaust Fluid (DEF). The truth about DEF – it’s not what you think ![]()
