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. ... This ammonia then breaks down and neutralizes the NOx gases.

Is DEF fluid made from urine?

Diesel exhaust fluid is not made of urine, and if you are going to urinate in your SCR system, you're looking at having to pay some pretty hefty repair costs to clean and replace engine components once they have been contaminated.

What is the main ingredient in DEF fluid?

Diesel Exhaust Fluid (DEF) which is composed of 32.5 percent urea and 67.5 percent deionized water.

What animal is DEF fluid made from?

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.

Can I pee in DEF tank?

But sadly, the answer is "no". A modern clean diesel car will recognize that your pee is not the right stuff. AdBlue solution has a far higher concentration of urea--32.5%--mixed into deionized water.

Can you drink DEF fluid?

Urea and consequently DEF is not overly toxic to humans. Urea can be irritating to eyes, skin and the respiratory tract but not life threatening. High concentrations in the blood can be damaging to humans however ingestion of low concentrations of urea ,given an adequate water ingestion of water, are not harmful.

What urea is in DEF?

Diesel Exhaust Fluid (DEF) is a non-hazardous solution, which is 32.5% urea and 67.5% de-ionized water. DEF is sprayed into the exhaust stream of diesel vehicles to break down dangerous NOx emissions into harmless nitrogen and water.

Is there a substitute for DEF fluid?

DEF is urea or otherwise known as aqueous ammonia. Windshield washer fluid that contains ammonia will do in a pinch. It contains less AA than needed but will get you to a town where you can get DEF.

Can you pour DEF down the drain?

Bad DEF should be disposed of immediately and ethically. Do not pour down a drain or dump it outside. Check with your local government and environmental agency to learn how to properly dispose of DEF.

Is there ammonia in DEF?

DEF is a non-hazardous solution comprised of 32.5-percent urea and 67.5-percent de-ionized water. It has a slight smell of ammonia, similar to some home cleaning agents.

Does DEF get old?

Shelf Life

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.

Does exhaust brake use more DEF fluid?

Using an exhaust brake does not directly use more fuel, but it does indirectly. When you use an exhaust brake, the exhaust is blocked and builds up in the engine. This slows the vehicle but also cools the glow plugs in a diesel engine.

Can you drive a diesel without DEF?

SCR Systems

Modern trucks will not run without the DEF. Hence the need for diesel truck owners to check their fluid levels frequently. Reducing emissions should be everyone's goal. Maintaining your vehicle would also reduce emissions and DEF consumption.

Is California banning DEF?

California will ban sales of new gas and diesel vehicles by 2035. In an executive order, Gov. Gavin Newsom said passenger vehicles will be required to have zero emissions. ... Gavin Newsom said passenger vehicles will be required to have zero emissions.

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.
