Quick Answer: Is DEF Fluid Made From Urine?

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..

Can I make my own def fluid?

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.

What year did def fluid become mandatory?

2010A: Because almost all diesel-powered passenger cars and trucks built since 2010 are equipped with Selective Catalytic Reduction (SCR) and require Diesel Exhaust Fluid (DEF), it is readily available at most fueling stations and automotive parts retail stores. Truck stops often have a DEF pump right on the fuel island.

How much def does a Sprinter van use?

Most DEF tanks for a Mercedes Benz Sprinter Van are about 6.6 gallons. You can get a 2.5 gallon refill tank of DEF for about $12.00, which is approximately $4.80 per gallon. So, it will take about $31.00 to completely fill up a DEF tank in a Sprinter Van.

Will def damage paint?

It will damage the paint if you leave it on there.” If left to dry on its own, DEF will turn into a white, powdery substance, which is a good indicator of a DEF leak and something drivers should watch for when conducting their pre-trip inspections.

Is DEF fluid made from pig urine?

If you’re thinking, “Urea. … But despite DEF earning the nickname “pig urine,” Diesel Exhaust Fluid is actually made of commercial-grade urea—synthetic ammonia and carbon. So, to simplify things: the urea and water in DEF heat up, producing ammonia.

Can you pee in your DEF tank?

The question comes up simply because human urine contains 2 to 4 percent urea. 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.

Is 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.

How long does def fuel last?

Most DEF tanks require one gallon of DEF for every 50 gallons of diesel fuel, and one gallon will generally last between 300 to 500 miles.

Is corrosive def?

Good news, Diesel Exhaust Fluid is classified as a non-hazardous material. However, it is corrosive to most metals. Stainless steel is the only metal used in manufacturing DEF pump equipment.

What kind of Urea is used in DEF fluid?

Diesel Exhaust Fluid (DEF) uses automotive-grade urea which has a much higher purity than fertilizer urea. Using a lower-quality fertilizer urea will cause degradation of the Selective Catalytic Reduction (SCR) system, eventually causing the truck to break down.

Given the open availability of this service, a farmer could be forgiven for believing that DEF modifications are legal. They’re not. In the U.S., the EPA Clean Air Act prohibits anyone from tampering with an emission control device on a motor vehicle by removing it or making it inoperable.

Can you delete def on Cummins?

A DEF Delete Service for your Cummins, Duramax, or Powerstroke diesel engine from Revolution Motors will remove this system so your truck is running at peak efficiency and performance. Trucks with the DEF delete install can improve fuel efficiency by up to 30%.

How often do you need to add diesel exhaust fluid?

For example, for every 100 gallons of diesel fuel consumed, between 2 and 4 gallons of DEF will be automatically injected into the exhaust system. The typical DEF tank will be approximately 15 – 20 gallons, thus requiring a fill every 5,000 to 6,000 miles.

How much does def cost?

The fluid’s cost is coming down from when it first appeared on the market, when it was more than $12 per gallon. A NAPA auto parts store in Columbus, Ohio, sells a 1-gallon jug of Valvoline-brand DEF for $5.79 and a 2-gallon jug for $11.99.

Why Def is bad?

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. If DEF enters the fuel system and spread throughout the engine it will ruin the diesel engine eventually.

Does def go bad in the tank?

The good news is, it’s a fairly long shelf life; DEF can usually be stored up to one year without any issues.

What is blue def used for?

Engineered for use in Selective Catalytic Reduction (SCR) systems on diesel engines, BlueDEF diesel exhaust fluid is comprised of a high-purity synthetic urea and deionized water mixture that improves emissions and fuel economy.
