DEF or Diesel Exhaust Fluid is a consumable fluid that primarily helps reduce harmful chemicals released in the atmosphere. With SCR or Selective Catalytic Reduction invented in the United States in 1957, these two work their magic together, especially when most engine manufacturers introduced it. While it might be new for some, there are still several myths surrounding this system.
DEF is Toxic
DEF is a non-hazardous and non-flammable fluid that helps slow down the pollution from chemicals in diesel alone. The fluid has a natural pH of 9.0, similar to the baking soda in your kitchen.
DEF is Urine
DEF contains urea, but it does not mean that it is urine altogether. Urea is a waste product of many living organisms. DEF is composed of synthetic urea produced since the 1930s by synthesizing synthetic ammonia and carbon dioxide in a heated and sealed process.
It is Hard to Use
Filling up your DEF tank is not a challenging task to do. It is as simple as putting water on your car’s radiator. There is also no need to refill your DEF tank every time you fill up your gas tank, as a 2.5 gallon of DEF can work for about 800 or more miles of travel.
DEF is Unstable
Diesel Exhaust Fluid or DEF is not tricky to store, especially with its components that do not quickly transform into a toxic chemical despite changing temperatures, making DEF stable.
You Can’t Easily Buy DEF
It is not a hassle to buy DEF for your vehicle, as it is readily available in truck stops, gasoline stations, and auto parts shops.
Only Professionals Can Fill Your Tank
You also do not need to ask for assistance from a professional filling up your DEF tank as it is not tricky to use. DEF tanks are usually convenient, making it easy to access that you can do it even if you are in your garage.
DEF is a non-toxic fluid that is available in several brands, and with that, the fluid could not cause any harm or damage to your car.
There is also no need to worry about your DEF evaporating, primarily if you use it for your auto. DEF only evaporates and turns into ammonia when displayed and constantly exposed at 120 degrees for two years.
DEF is a New Invention
The SCR and DEF system has been around for some time now, especially in commercial and agricultural applications. While it may sound new to the ears of those who do not have a DEF tank, it is nothing new.
DEF has More Cons Than Pros
While DEF has its cons, like increased operating cost, and the addition of a small amount of weight, its pros can outweigh these disadvantages. The pros of DEF include better fuel efficiency, increased power, and reduced maintenance for your vehicle, among many others.
