How does adblue work

Heated in the exhaust, it decomposes into ammonia and CO₂. When the NOx from the engine exhaust reacts inside the catalyst with the ammonia, the harmful NOx …

How many miles will 10 Litres of AdBlue last?

How long does AdBlue last? According to GreenChem, a typical mid-sized diesel car will travel 1,000km (620 miles or so) on a single litre of AdBlue. Most AdBlue tanks hold around 10 litres or more, so you may find it won’t need to be topped up until the next scheduled service.

Can you use water instead of AdBlue?

If you fill up with water instead of AdBlue, you can block the injector and damage the catalyst. Progressive damage to your SCR system can reduce engine performance and actually increase the fuel consumption per mile or kilometer. Your vehicle will not maintain the emissions allowed for a Euro 6 car.

Where does AdBlue get injected?

AdBlue is injected from the vehicle’s dedicated AdBlue storage tank into the exhaust pipe, which is in front of the SCR catalyst, but downstream of the engine. As it is heated in the exhaust, the AdBlue changes into ammonia (NH₃) and carbon dioxide (CO₂).

Can a car run without AdBlue?

You should never let your car run out of AdBlue. If it does, the engine will go into ‘limp’ mode, which drastically reduces power to keep NOx emissions within legal limits. If that happens, a warning will appear on the driver’s display and you should refill the AdBlue tank as soon as possible.

What happens if a diesel runs out of AdBlue?


If you run out of AdBlue while you’re driving, then the engine’s power and performance will be reduced to limit its emissions. Once you’ve stopped, you won’t be able to restart the engine if the AdBlue tank’s empty. The car will give you plenty of warning that the AdBlue tank’s running low.

Can a diesel run without AdBlue?

Without AdBlue, most modern diesel engines will automatically de-rate and won’t operate beyond moving the truck off the road.

Can I wee in the AdBlue 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 I make AdBlue at home?

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.

How long can I drive after AdBlue warning?

Most vehicles which require adblue will give you a warning when there’s about 2-3 litres left. Depending on the vehicle and how you drive it, this will give you about 1,200 to 1,500 mile range.

Why did China stop exporting AdBlue?

At the time, around 80% of Australia’s urea had been imported from China, which has the world’s richest supply. However, China banned the chemical’s export in order to lower fertiliser prices domestically.

Which country produces the most AdBlue?

Yara International ASA, the number one producer of AdBlue, opens the world’s largest production capacity in Brunsbüttel, Germany. The new facility has a production capacity of 1.1 million tons of AdBlue per year.

Is AdBlue made in Ukraine?

AZMOL BP is the only Ukrainian manufacturer that has received a license to manufacture AdBlue reagent. Obtaining it is a long and laborious process, but well-established production, high-quality materials and full compliance with the recommendations guarantee a positive result.

What is the alternative to AdBlue?

Replacing AdBlue with distilled water will have no impact on emissions whatsoever and may damage your engine.

How far can you go without AdBlue?

1 litre of AdBlue lasts around 600 miles, but this can be affected by your driving style. The more fuel your vehicle uses, the more AdBlue it will consume as well. However, travelling 6,000 – 7,000 miles will empty your tank. We recommend topping up every 5,000 miles to be safe.

Why is AdBlue doubled in price?

AdBlue has surged significantly in price amid a shortage of refined urea, a key ingredient used in the diesel exhaust fluid.

What is the lifespan of AdBlue?

12 months

WHAT IS THE SHELF-LIFE OF ADBLUE®? The shelf-life of AdBlue® should last for up to 12 months as long as it is stored in the correct manner (please refer to the Material Safety Data Sheet and the labelling on the packed AdBlue® container).

Why you should never run out of diesel?

Running low on diesel can also damage your fuel system. That’s because the poorest-quality fuel settles at the bottom of the tank, and it’s often full of sediment.

Why is my car using so much AdBlue?

An indicator that your AdBlue may be contaminated is an uptick in AdBlue consumption, a selective catalytic reduction (SCR) system malfunction, or quite simply, the engine shuts down. The ideal concentration of urea-based AdBlue is 32.5-37%. These problems may occur if this ratio is off, indicating a contamination.

Can you mix diesel and AdBlue?

AdBlue is commonly mistaken as a fuel additive when it is actually an exhaust fluid that should never be mixed with diesel. AdBlue has its own tank and is stored completely separately to your vehicle’s fuel. Adding AdBlue into your diesel fuel tank can cause thousands of pounds worth of damage.

Do modern diesel cars use AdBlue?

AdBlue has become increasingly common amongst modern diesel-powered vehicles. What is AdBlue? In simple terms, AdBlue is a liquid designed to reduce the amount of emissions generated from modern diesel engines. Technically-speaking, AdBlue is a solution made from 32.5 per cent urea and 67.5 per cent deionized water.

How do you restart your car after running out of AdBlue?

The only way to restart the car after the tank has been run dry is to refill with AdBlue of the specified quality, minimum 3 litres.

What is the main ingredient of AdBlue?


AdBlue® is made of a colourless mixture of high-purity urea (32.5%) and deionised water (67.5%), as set out in the ISO 22242 standard. Urea contains ammonia; the active ingredient in AdBlue® that reacts with NOx and neutralises it before it enters the atmosphere.

Can you use ammonia instead of AdBlue?

Because ammonia gas has a low temperature and high pressure in a liquid state, once it leaks, it will cause frostbite and poisoning to the human body.

Where does urea come from for AdBlue?

Urea is produced synthetically from ammonia and CO₂ (carbon dioxide), from which Yara’s AdBlue is extracted directly as "hot melt" urea, which uses a different process from fertilizer grade urea.

How do I know when AdBlue tank is full?

Heavy goods vehicles are equipped with a gauge showing how much AdBlue® is left in the tank. Light vehicles have a visual warning light on the dashboard that comes on when the vehicle can still cover 2,400km, showing that it is time to think about topping up.

Is AdBlue cheaper at the pump?

The price of AdBlue will depend on the quantities that you order. In general, the price of AdBlue per litre is around 50% that of the fuel price at the pump, so it is much cheaper.

What problems can AdBlue cause?

AdBlue Systems Issues Most common problems are: heating failure, freezing of AdBlue and the resulting expansion damage to the system, nozzle failure, NOx sensor failure, pump failure, and failure of AdBlue system control unit. Especially fragile iteration of this system is found on Mercedes cars (BLUETEC).

Why can’t Australia make urea?

The main domestic producer of urea in Australia, Incitec Pivot’s Gibson Island plant in Queensland, is due to close in 2022 after it failed to source affordable gas, further increasing the country’s reliance on imports.

Why is there no AdBlue in Australia?

There was a national shortage of it late last year when China stopped exporting urea, the key ingredient in AdBlue. In response, the Morrison government tipped almost $30 million into Incitec Pivot to ramp up AdBlue manufacturing at its facility in Queensland which catered to most of Australia’s requirements.

Who invented AdBlue?


Tetrosyl launched AdBlue under the Carlube brand back in 2009, however, it is only recently that AdBlue has come to the forefront of many diesel driver’s minds, but many still do not know what it is, what it does and why your diesel car needs it.

Tony Conover

Tony Conover, owner of Conover Racing & Restorations, Inc., has been in the car restoration business since 1977. His love of the Ford Mustang and Shelby, along with his vast knowledge of the history of these cars, led him to focus on Ford's classic muscle cars since 1977, with particular focus on Shelby Mustangs, and he believes that he has probably restored more R-models than any other restoration shop in the country. He fondly remembers the overwhelming originality of 5R531, which retained all of its original sheet metal, a far cry from many of the exhaustively raced and frequently damaged examples that have passed through his care over the years. Following Mr. Conover’s exacting year-long restoration, the car was bought in September 1990 by Buddy Belzer, of Rapid City, South Dakota, and soon after, it embarked on a successful exhibition run. Presented at the SAAC-18 meet at Watkins Glen in July 1993, 5R531 drove away with the 3rd place Popular Vote in the R-model class.
