The SCR or Selective Catalytic Reduction was invented in the United States back in 1957, and it has been proven to reduce nitrogen oxides that damage the environment. Today, SCR systems are introduced by many engine manufacturers along with the DEF or diesel exhaust fluid, which is a consumable fluid that helps reduce harmful chemicals released in the atmosphere. While this has been around for quite a while, this technology may still be unfamiliar to some. There are also some myths below that surround this system.
DEF is Toxic
DEF is a non-toxic, non-hazardous, and non-flammable liquid that helps slow down the pollution of harmful chemicals in diesel.
DEF is Urine
While DEF contains urea, it does not automatically mean it is urine altogether. In a heated and sealed process, synthetic urea in DEF is produced by synthesizing synthetic ammonia and carbon dioxide.
It is Hard to Use
Filling up a DEF tank is not difficult, as it is as simple and easy 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 gal diesel exhaust fluid is enough for around 800 or more miles of travel on the road.
DEF is Unstable
Diesel Exhaust Fluid is not hard to store as its components do not transform into hazardous and toxic chemicals despite temperature changes.
You Can’t Easily Buy DEF
There is no hassle buying DEF as it is available in truck stops, gasoline stations, and auto parts shops. Additionally, you can even purchase it online, as it ranges from $2.50 to $8 per gallon.
Only Professionals Can Fill Your Tank
There is no need for professional help to fill up your DEF tank for you, making it convenient to access as you can do it even in your garage.
Non-Factory DEF Will Damage My Car
While there are several brands of DEF, this non-toxic fluid could not cause any harm or damage to your vehicle.
There is no worry about your DEF evaporating as you use it for your car, especially if it is not constantly exposed at 120 degrees that could turn it into ammonia.
DEF is a New Invention
As SCR and DEF systems have been used for quite a while, utilized by commercial and agricultural applications, this is nothing new even though it may sound foreign to car owners who do not have a DEF tank.
DEF has More Cons Than Pros
There are several benefits to using DEF, such as better fuel efficiency and reduced maintenance, making it a worthy investment for your vehicle in the long run.
