Contrary to popular myth, cow and bat urine and DEF are not a thing. The urea used in the manufacture of DEF is synthetically derived from ammonia and carbon dioxide, and urea production plants are often adjacent to other sites where ammonia is produced, such as coal and natural gas refineries.

Is DEF fluid made from urine?

DEF is a mixture of (typically) 2/3 deionized water and 1/3 urea. It's carefully regulated by the American Petroleum Institute. Technically, urea is derived from one of the byproducts of urine. But it's synthetically made, so no cats are ever harmed in the production of the fluid.

Is there horse urine in DEF fluid?

The short answer is no. Commercially available DEF does not contain any animal urine.

Can urine be used as DEF?

The urea that DEF contains is synthetically made. Because urea is also present in urine, there is a misconception that DEF contains urine and that urine and DEF are interchangeable. Some rumors say that cow or bat urine is used to make DEF. This is, to be blunt, absolutely not true.

What is DEF exhaust fluid made of?

What Is DEF Fluid Made of? Diesel Exhaust Fluid (DEF) which is composed of 32.5 percent urea and 67.5 percent deionized water. For those who like trivia, urea is considered to be the first organic compound to be synthesized from inorganic chemicals.

Is DEF made from pig urine?

Urea is an organic compound produced when a body metabolizes protein. (And yes, we expel it as urine.) But despite DEF earning the nickname “pig urine,” Diesel Exhaust Fluid is actually made of commercial-grade urea—synthetic ammonia and carbon.

Where does the urea in DEF come from?

Contrary to popular myth, cow and bat urine and DEF are not a thing. The urea used in the manufacture of DEF is synthetically derived from ammonia and carbon dioxide, and urea production plants are often adjacent to other sites where ammonia is produced, such as coal and natural gas refineries.

How do you make def fluid?

From a strictly chemical disposition DEF is a mixture of 67.5% deionized water and 32.5% urea. Urea is a compound in Nitrogen that turns to ammonia when heated and is used in a variety of industries. Urea is technically derived from a byproduct of urine but for mass production purposes it is synthetically made.

How is DEF manufactured?

Our DEF is produced from a solution of high-purity, virgin urea. Urea is produced synthetically from ammonia and CO₂ (carbon dioxide), from which Yara's DEF is extracted directly as "hot melt" urea, which uses a different process from fertilizer grade urea.

What happens if you pee in the DEF tank?

Please do not urinate in your DEF tank, the SCR system will be damaged and it will cost thousands of dollars to repair.

Why is there a DEF shortage?

Skyrocketing natural gas prices in the EU have driven up manufacturing costs, significantly increasing the cost of DEF. Chinese and Russian Restrictions – China, a key supplier of urea, has restricted exports to curb domestic shortages.

Does DEF really help the environment?

How Does DEF Use Affect the Environment? According to the EPA, in the decade since SCR's inception, hazardous emissions have dropped more than 40%. Over-the-road trucking and corporate or government fleet vehicles equipped with DEF tanks have had the single greatest positive effect on that number.

Where does DEF come from?

DEF is made from deionized water and a very pure form of urea. Yes, urea is found in urine -- quit giggling, please -- but this is a refined form of the compound and is mostly used in the agricultural industry as a component of fertilizer.

Is DEF fluid harmful to the environment?

While it's good for the environment, the water and urea mixture can result in the formation of crystals that can plug up fuel filters, damage aircraft engines, and result in engine failure. DEF should never be used as an additive for any fuel, diesel or aircraft, and is sprayed directly into exhaust systems.

Who makes Blue def fluid?

Such complex systems are bound to require repairs, but family-owned automotive aftermarket company Old World Industries, the manufacturer of leading brands such as BlueDEF® and PEAK®, is sharing several insights to ensure your diesel exhaust system runs smoothly to avoid insanely expensive repairs.

Can you put water in DEF tank?

The DEF will be diluted by the added water, but depending on the ratio of water to DEF, the solution may still contain enough urea to deal with the NOX via an increase in the injection rate.

What does Blue def?

BlueDEF® Diesel Exhaust Fluid is a mixture of high purity synthetic urea and deionized water that is used in Selective Catalytic Reduction (SCR) systems in diesel vehicles. DEF is used to help convert NOx to harmless nitrogen and water.

Does DEF go bad?

Because it doesn't include any preservatives, DEF does come with a shelf life. The good news is, it's a fairly long shelf life; DEF can usually be stored up to one year without any issues.

Is urea and urine the same thing?

Urea is the chief nitrogenous waste, which is eliminated through urine. Urea is produced in the liver from ammonia, which is a metabolite of amino acids and carbon dioxide. Urine is formed by the nephrons after filtration, secretion and reabsorption.

What can you use instead of DEF fluid?

DEF is urea or otherwise known as aqueous ammonia. Windshield washer fluid that contains ammonia will do in a pinch.

Is DEF made from coal?

The raw materials used to produce DEF include natural gas, coal or other petroleum products.

Does DEF hurt your engine?

Diesel Exhaust Fluid (DEF) is not toxic, harmful or dangerous. In fact, of all the fluids used in a truck, such as diesel, engine oil, brake fluid, antifreeze and windscreen wash, DEF is the least hazardous.

Is DEF fluid eco friendly?

Diesel Exhaust Fluid, or DEF, is a critical liquid for a functioning, efficient, eco-friendly vehicle. It's flushed through a Selective Catalytics Reduction (SCR) system, and it helps the environment by reducing the truck's nitrogen oxide (NOx) emissions.

Why is DEF bad for diesel engines?

The presence of DEF can cause overheating and engine failure in colder climates (12-16 degrees Fahrenheit). A component of the SCR that is contaminated by other fluids such as diesel fuel, coolant, or engine oil, may shut down the SCR system and stall the engine.
