How Do They Make Def Fluid? 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.
What is DEF fluid made of? DEF, available at most service stations for $6 to $10 per gallon, is a fluid consisting of urea and deionized water in a 1:2 solution. It’s contained in a reservoir separate from the fuel tank and is metered into the engine’s exhaust stream to control certain emissions.
Why Def is bad? Studies show that it would have to be a constant 120 °F for about two years before the DEF would turn into ammonia and disappear. And it’s not a toxic chemical either. In fact, many fluids in your truck (like diesel fuel, engine oil, wiper fluid, brake fluid and more) are much higher in their toxicity level.
Can I use water as DEF fluid? For the O/O’s using DEF, you can use distilled water instead. Basically DEF is 33% urea and 67% deionized water. So, in an emergency you could use a mixture of 1/3 pee and 2/3 distilled water.

Is Blue def cow urine?
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.
Does def ruin engine?
Simply dumping diesel fuel in the DEF and vice versa (DEF in the fuel tank) will not harm your engine if you do not start the engine. If the engine is started for even a short time diesel fuel will ruin the SCR catalyst which is very costly to replace and will be out of warranty.
Is a def delete illegal?

If the reservoir is not replenished with DEF and runs low, vehicle speed will be limited, but as soon as DEF is added, the engine will resume normal speed levels.
Can I drive my diesel without def?
The U.S. Environmental Protection Agency requires vehicle manufacturers to put measures in place to ensure that vehicles cannot run without Diesel Exhaust Fluid (DEF).
Are all DEF fluid the same?
DEF fluids all must meet an international standard and standards from the EPA that measure the purity of this fluid. Only purchase a DEF that meets the ISO 22241 standard. Sometimes, inexpensive bottles of fluid may claim to be DEF-compatible. However, if they don’t also meet the ISO 22241 standard, they are not DEF.
Is urine in def?
While urea definitely is a component of both urine and DEF, the manufacture of DEF is done under exacting conditions making sure the urea is pure and free of contamination, and of the right ratio to the deionized water. The water also must be of an exact quality.

Is DEF fluid 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.
How long can def be stored?
The quality of DEF also is not affected if the fluid freezes. When stored under optimal conditions — between 12°F and 86°F — DEF has a shelf life of up to two years. If stored in warmer temperatures, shelf life decreases.
How many miles per gallon does def get?
DEF consumption is directly related to fuel consumption. A truck averaging 6 MPG can expect to go approximately 300 miles on one gallon of DEF.
Can you make your own def?
DEF is 32.5 percent high purity urea and 67.5 percent demineralized water. But don’t think you can save some money and make your own DEF. Agricultural grade urea or UAN (urea ammonium nitrate) should never be used in place of DEF.
