What Is AdBlue For Diesel Engines?

The brand name AdBlue refers to a type of diesel exhaust fluid. It’s a mixture of urea and deionized water kept separate from the car’s fuel in a separate tank.

Tiny amounts of AdBlue are squirted into the exhaust gas produced by the car’s engine, converting NOx to nitrogen and water.

What happens when you run out of AdBlue?

What happens if you run out of AdBlue in your car? If you run out of AdBlue while driving, the engine’s power and performance will be lowered to ‘limp home’ mode to decrease emissions, and the engine will not start again until the AdBlue tank is replaced.

Do all diesels need AdBlue?

AdBlue is used in many diesel cars that fulfill Euro 6 emissions requirements. However, not all do, as there are various technologies that can be utilized to reduce NOx emissions instead.

There are so many AdBlue-using vehicles that there isn’t enough room to mention them all here. Still, here are some hints to see if the vehicle you wish to buy uses AdBlue:

  • Check to see if the car’s name includes the words ‘blue’ or the initials ‘SCR.’ Peugeot and Citroen diesels that use AdBlue, for example, are labeled BlueHDi. EcoBlue is a Ford brand. TDi SCR is a Volkswagen badge.
  • Check for the blue-capped AdBlue filler described previously by opening the gasoline filler flap. Ask the dealer or the manufacturer if you’re still unsure.

Can I refill AdBlue myself?

Is it possible for me to add AdBlue to my account? Yes, you may add AdBlue to your account yourself. AdBlue is sold in standard 5L and 10L cans at every TotalEnergies service station. TotalEnergies is also gradually introducing light vehicle-specific pumps.

How often does AdBlue need to be refilled?

AdBlue: If you’re driving one of the latest Euro6 diesel automobiles with low emissions, you’ve probably already topped up the specific tank with the additive. But, if you’ve never heard of this new chemical, what is it, why is it crucial to the health of your car, and how often should you add it to keep it in good shape? The do’s and don’ts of using AdBlue are detailed here.

New Euro6 emissions limits for diesel cars went into effect in September 2015 (a year later for vans), with the goal of reducing a variety of hazardous chemicals connected to respiratory ailments.

The new restrictions are particularly focused on nitrogen oxides (NOx), which have been reduced from 180 mg/km to merely 80 mg/km. The goal is to reduce these hazardous emissions, hence limiting the environmental and public health consequences.

Many major European cities, including London and Paris, are considering banning diesels that do not satisfy Euro6 rules at certain times and on specific days.

To fulfill the new standards, carmakers have mostly relied on a technology known as Selective Catalytic Reduction, which entails injecting a diesel exhaust fluid (DEF) into existing gas circulatory systems to aid in the breakdown of toxic NOx. AdBlue is the common name for this DEF.

Clean Air Zones, such as London’s Ultra Low Emission Zone, require diesel cars and vans to be Euro6 compliant, or a daily fee will be imposed.

AdBlue is a synthetic urea that operates by converting nitrogen oxide to steam and nitrogen, which are both safe. It’s kept in a tank like petrol, and AdBlue tanks are being installed in an increasing number of diesel vehicles, particularly those with larger engines. Certain producers, on the other hand, may simply refer to it as “Emissions Additive.”

AdBlue is not a gasoline additive that is pumped into the engine. It’s added to the car’s exhaust system’s catalyst system.

The amount of AdBlue consumed is proportional to the amount of time the engine is used. A typical car will use about 1.5 litres of AdBlue every 620 miles, according to estimates. Because AdBlue tanks come in a variety of sizes, when you need to refuel is determined by your driving style, the amount of miles you drive, and the size of the tank. When it’s time to refuel, a dashboard warning light will illuminate.

AdBlue has been widely used on trucks and buses since 2006, when Euro4 rules were implemented for those vehicle classes.

AdBlue is seen as a consumable, analogous to gasoline. As a result, it is the driver’s responsibility to keep the AdBlue tank topped off and to pay any associated charges. AdBlue should never be used as a gasoline additive. AdBlue is kept in a separate tank at all times. In many vehicles, however, the AdBlue filler will be close to the fuel filler.

Any damage done as a result of AdBlue misuse, such as adding it to either petrol or diesel tanks, or a breakdown caused by low AdBlue levels, will not be covered under maintenance or recovery agreements.

AdBlue expenditures are not covered by maintained lease contracts. Certain leasing providers, on the other hand, will top up AdBlue as part of a standard service.

By reviewing their vehicle handbook, drivers can become more aware of their obligations.

  • AdBlue is an emissions reduction solution that complements existing DPF technology and is exclusively relevant to diesel engines.
  • A DPF-equipped diesel vehicle may or may not have an AdBlue tank. Cars with an AdBlue tank, on the other hand, always have a DPF as part of the entire emission control package.
  • The AdBlue and DPF warning lights are independent of one another and will illuminate at different times.
  • AdBlue is added to the right kind of fuel for the right kind of person. Driving style, journey type, engine and vehicle load, and environmental variables all influence usage.
  • AdBlue can be acquired at car dealers, garages, dealerships, and some gas stations, as well as online. In general, a 10 litre container of AdBlue costs roughly £12.50 at Halfords.
  • The position of the AdBlue filling varies by manufacturer and model. The boot, next to the gasoline filler, or under the hood are all common positions.
  • Because the size of the AdBlue tank installed in vehicles varies by manufacturer and model, the time between top-ups will also vary.
  • AdBlue may need to be topped up every 5,000 to 8,000 miles, according to conservative estimates, though this can vary depending on the brand, model, and driving style.
  • In rare cases, such as as part of a normal servicing, some manufacturers may give AdBlue for free. However, it’s quite improbable that refills during typical servings will be enough to keep AdBlue levels stable.
  • Variable-service vehicles demand special attention because an AdBlue top-up is almost always required before the initial service.
  • When AdBlue levels are low, the driver information system will issue a series of alerts. Audi models, for example, show a countdown from 1,500 kilometers to a required refill.
  • It is critical that these warnings are heeded as soon as possible. The automobile will continue to run on reduced power if AdBlue falls below a predetermined threshold. It will not restart once it has been stopped until enough AdBlue has been injected. You will be charged for recovery if this happens on the side of the road.
  • For example, to restart an Audi, a minimum of 5.7 litres of AdBlue is necessary, albeit this number varies between manufacturers.
  • AdBlue should never be used as a gasoline additive. If AdBlue is put through the fuel filler, the vehicle should not be started and the relevant emergency assistance number should be called immediately.
  • If you mistakenly put petrol in the AdBlue tank, the same rules apply: don’t start the car and call the appropriate emergency number right away.

Is it OK to drive without AdBlue?

If you run out of AdBlue while driving, the engine’s power and performance will be decreased to keep emissions to a minimum. If the AdBlue tank is empty when you stop, you won’t be able to restart the engine.

When the AdBlue tank is low, the automobile will give you plenty of warning. At about 1500 miles, you’ll see a text warning on the dashboard, followed by an amber caution light.

How do I know if I need AdBlue?

AdBlue is sold in 10-litre and 20-litre containers at auto accessories stores and gas stations. It’s also available to purchase online, and some gas stations offer it at the pump. If you buy it in a container, expect to pay roughly £1.50 per litre, or around 60p per litre at a service station pump.

What happens if my car runs out of AdBlue?

When AdBlue starts to run low, most cars will glow a dashboard warning light; this normally illuminates when there’s around three litres of fluid left, allowing you about 1200 miles to refill it.

Is AdBlue made from pigs urine?

Is AdBlue created from the pee of pigs? AdBlue is a highly pure synthetic urea and demineralized water solution, not pig urine. While urea is present in pig urine, it is present in considerably lower concentrations than many other components.

Can trucks run without AdBlue?

AdBlue is a liquid that is pumped into the exhaust systems of diesel engines. It’s a combination of urea and deionized water that transforms nitrogen oxides into nitrogen and water, lowering hazardous emissions dramatically. The blue AdBlue cap that sits beside the diesel fuel cap on later model cars and 4WDs may be familiar, although trucks have a separate AdBlue tank and fill point.

Without it, modern diesel engines will go into ‘limp mode,’ which means that if supplies run out, thousands of trucks will be practically unable to operate.

How do you know when AdBlue tank is full?

Simply pour the solution into the car and drive until it’s full. Most AdBlue-equipped vehicles will have a gauge buried someplace in the car’s infotainment system that shows how full the tank is. You’ll know how much AdBlue you need if you keep looking until you discover it.
