The SCR or Selective Catalytic Reduction has been around for a while now as it was invented in the United States in 1957. Today, it was introduced by most engine manufacturers as it works well with DEF or Diesel Exhaust Fluid. This consumable fluid can reduce harmful chemicals that are released into the atmosphere. Several myths, such as the following, also surround this system.
DEF is Toxic
DEF is a non-toxic, non-hazardous, and non-flammable fluid that can help slow down pollution brought by harmful chemicals in diesel. DEF also helps in releasing nitrogen and water.
DEF is Urine
While DEF contains urea, it does not mean that it is synonymous with urine. Urea is a component of the waste products of living organisms. But DEF contains synthetic urea that has been produced by combining synthetic ammonia and carbon dioxide in a sealed process.
It is Hard to Use
Filling up your DEF tank is not a difficult task because it is a 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 2.5 gallons is enough for around 800 miles of travel.
DEF is Unstable
DEF is not difficult to store as it does not transform quickly into a toxic chemical despite temperature changes, making it stable.
You Can’t Easily Buy DEF
You can purchase DEF from truck stops, gasoline stations, and auto parts shops for at least $8 per gallon, but cheaper DEF options are also. Another plus is you can even purchase it online.
Only Professionals Can Fill Your Tank
DEF is not tricky to use, and you can fill up your tank on your own with no problem. There is no need for professional help to fill it up for you, making it convenient and accessible as you can do it even in your garage.
Non-Factory DEF Will Damage My Car
DEF is non-toxic, and using this fluid cannot harm or damage your car as it is a chemical with a mixture of water and nitrogen.
DEF Evaporates
You can stop worrying about DEF evaporating if you will use it for your car. It can only disappear if DEF is displayed and constantly exposed at 120 degrees for two years, turning it into ammonia and evaporating.
DEF is a New Invention
The SCR and DEF system has been around for some time now, as it is utilized for commercial and agricultural applications.
DEF has More Cons Than Pros
Some pros of DEF make it a worthy investment, such as its better fuel efficiency and reduced maintenance for your auto. While it has some cons, such as increased operating costs and requiring more room for your truck, DEF is still worth trying, especially as it can be considered an eco-friendly option.
