Typically, the consumption rate is 2% to 4% of diesel consumption.

You wonвЂ™t have to refill your DEF tank every time you fill up with fuel.

DEF has been shown to improve fuel economy by about 5%, and uses the diesel fuel more efficiently.

ItвЂ™s easy to carry some in your vehicle in case you run low.

If you get some on your skin or in your eyes, wash with soap and water. ItвЂ™s not flammable, nor becomes toxic at any temperature.As of 2014, off-road vehicles like those used in agriculture and construction, are also required to have SCR and use DEF for emissions reduction. This includes pickup trucks, heavy-duty trucks and vans, as well as several European diesel luxury cars and SUVs. Nearly all diesel vehicles made since 2010 have SCR, requiring the use of DEF. OEM companies also began incorporating SCR into their engines without changing the engine design or operations.

SCR technology is designed to reduce nitrous oxides (NOx) emissions. Since 2008, the EPA has required diesel truck manufacturers to implement SCR technology in vehicle. SCR systems are calibrated to use the 32.5% urea/67.5% concentration. Nitrogen and water are now released into the atmosphere. Ammonia molecules then react in the exhaust stream, and neutralize the NOx molecules. Using the Selective Catalytic Reduction (SCR) system now required on all diesel vehicles, the catalytic converter causes the water to evaporate and the urea to convert to ammonia on a catalyst. Urea is also used as agricultural fertilizer, animal feed, cleaning products, plastics, and pharmaceuticals. ItвЂ™s not a fuel additive, and is added to a separate tank thatвЂ™s easy to refill (usually with a blue cap.) Therefore, it never comes in contact with the fuel itself, and generally doesnвЂ™t impact fuel mileage.ДEF is a solution of 67.5% de-ionized water and 32.5% urea, a compound of nitrogen that, when heated, turns into ammonia. If you are considering converting your fleet (or your personal vehicle) to diesel, youвЂ™ll need one more consumable in order to run your vehicle: Diesel Exhaust Fluid or DEF.
