Can you use pee as diesel exhaust fluid?

We have also heard of people thinking that urinating in their DEF tank will make the engine run. So the common misconception people have about Diesel Exhaust Fluid is that it is made from urine. This is NOT true, and acting upon this idea could cost you thousands of dollars in repairs to your SCR engine.

What can I 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. It contains less AA than needed but will get you to a town where you can get DEF.

Can I use urine instead of AdBlue?

Using pigs’ urine (or any urine) instead of AdBlue® would cause irreversible damage to the SCR system in your vehicles.

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 cow urine in DEF?

Does DEF contain urine? The short answer is no. Diesel exhaust fluid sold in stores and at semi-truck pumps at truck stops in the U.S. does not contain urea derived from cows, bats, or any other animal’s urine, and to be clear, diesel owners should under no circumstances urinate in their DEF tanks.

Can you use DEF as fertilizer?

Why would you want to, it’s it would make for an awfully expensive fertilizer. DEF is 32.5\% urea and 67.5\% de-ionized water. Urea is 46-0-0, meaning it’s all nitrogen, no phosphorus or potassium. Nitrogen by itself can be harmful.

Can I use water as DEF fluid?

If you put water in an EMPTY DEF tank, there will be no urea injected into the exhaust to convert to ammonia. Ammonia is an essential requirement to eliminate NOX (Oxides of Nitrogen) via the SCR (Selective Catalytic Reducer).

Can you run water instead of DEF?

If you remove the urea from the DEF — that is, if you run water through the injectors instead — it probably won’t hurt anything, since you’re reducing the level and quantity of corrosive reactants inside the stainless steel SCR system.

What happens if you run without AdBlue?

What happens if I run out of AdBlue/don’t use AdBlue? When your SCR-equipped vehicle’s AdBlue levels are running low, a warning alert will appear on the dashboard. If it runs out of completely, the car will lose power and reduce its emission in line with legal standards.

Can I make my own AdBlue?

It can only be produced industrially. Making AdBlue® yourself may have adverse repercussions on your vehicle. the first involves dissolving granules of solid urea, called prills in demineralised water; the second involves mixing synthetic urea with demineralised water.

What kind of urine is in DEF?

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.

Can you dilute DEF fluid?

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.
