10 Myths and Facts About Diesel Exhaust Fluid

SCR or Selective Catalytic Reduction was invented in 1957 in the United States. Today, its use was finally introduced by many engine manufacturers. It works well along with DEF or Diesel Engine Fluid which helps reduce harmful chemicals in the atmosphere. In line with this, some myths revolve around SEF and SCR that we will debunk.

DEF is Toxic

DEF is a non-toxic, non-hazardous, and non-flammable fluid that helps slow down the pollution brought by harmful chemicals in diesel. During the exhaustion process in your car, DEF helps in releasing nitrogen and water.

DEF is Urine

While DEF contains urea, it does not mean that it is urine altogether. Urea is a component of the waste products of many organisms. However, synthetic urea has been produced since the 1930s through the synthesis of ammonia and carbon dioxide.

It is Hard to Use

Filling up a DEF tank is not difficult; it is as simple as putting water on your car’s radiator. A 2.5 gallon is enough for around 800 miles of travel.

DEF is Unstable

Diesel exhaust fluid is not hard to store since it does not quickly transform into a toxic chemical despite any temperature changes, making it stable.

You Can’t Easily Buy DEF.

There is DEF available in many truck stops, gasoline stations, and auto parts shops for around $8 per gallon, and there are also options available that you can even purchase online.

Only Professionals Can Fill Your Tank

DEF is not tricky to use, meaning you can fill your tank, making it convenient and easy. There is no need to ask a professional to fill it up for you. You can use precision fluid dispensing systems to deliver an accurate volume of fluids into your tank.

Non-Factory DEF Will Damage My Car

DEF may sound intimidating, but it is just a term used to refer to a chemical with a mixture of water and nitrogen. As DEF is non-toxic, it will not cause any harm or damage to your car.

DEF Evaporates

DEF cannot evaporate unless it is constantly exposed to 20 degrees for about two years, turning it into ammonia.

DEF is a New Invention

DEF has been around for a long time as it has been used for commercial and agricultural purposes. While it may sound new, as several vehicles do not have a DEF tank, this is not a new invention.

DEF has more cons than pros

Some cons of DEF include a rise in your operating cost, requires more room for your truck, and adds some weight. However, its cons, such as fuel efficiency and reduced maintenance, make it worth the investment in the long run.
