What Does AdBlue Do For Diesel Engines?

AdBlue, also known as Diesel Exhaust Fluid or AUS 32, is a clear mixture of demineralized water and pure urea (32.5 percent). Its purpose is to convert dangerous nitrogen oxide (NOx) emissions from diesel automobiles to non-hazardous gases in order to meet more severe emission requirements.

What happens if you dont use 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.

Does AdBlue affect performance?

If you’re running low on AdBlue, all diesel cars will give you plenty of notice. When you’re around 1,500 miles from running out, you’ll normally get a dashboard warning and an amber caution light. Until the AdBlue levels have been topped up to the required level, this warning will appear every time you restart your car.

What happens if you run out of AdBlue?

It is never a good idea to ignore the AdBlue warning light on your dashboard. If you run out of AdBlue while driving, your car’s performance will likely suffer as it attempts to cut emissions by entering ‘limp mode,’ lowering the speed at which you can travel, and occasionally turning off your vehicle’s audio or air conditioning to conserve power.

The majority of modern automobiles can’t be started while the AdBlue tank is empty once they’ve stopped. Fortunately, this is a situation that can easily be avoided because AdBlue refills are simple and usually inexpensive if you search about and do them yourself.

Can you drive a diesel without AdBlue?

DEF-required engines are very new, and most diesels built prior to 2019 do not require DEFs or AdBlue.

Trucking companies must pay more to convey goods because to the rising cost of AdBlue, and this cost is passed on to consumers at the supermarket.

If a reliable supply cannot be secured soon and you need to stick to a budget, your Christmas turkey or ham may have to be replaced with chicken or bacon.

A crisis should be avoided if quick action is made to secure a steady supply while seeking for domestic manufacturing prospects.

What to do

If you realize you’ve made a mistake while filling your tank, don’t start your car. Several litres of AdBlue can be contaminated by a single drop of Diesel. You risk causing major harm to your vehicle’s SCR system if you start with an AdBlue tank full of Diesel.

If you start your car, it will start acting weirdly. To avoid causing extra damage to your vehicle, pull over as soon as feasible.

Call a professional

Contact a mechanic or a repairman as soon as you realize you’ve filled the AdBlue tank incorrectly. They will know how to handle the matter, whether or not you have started your vehicle: draining and cleaning the AdBlue tank, and replacing any necessary parts.

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 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.

Is AdBlue bad for paintwork?

Yes, opening the AdBlue filler cap and pouring the liquid in is all that’s required. If you need to top up the fluids yourself, your dealership may promise to do so when your car is serviced, but here’s how to do it.

To avoid spilling, most bottles have a nozzle or spout that seals into the filler tube. Because AdBlue is highly corrosive and can harm paintwork, this is critical. If any lands on your car, it needs to be cleaned off right away with water (or hands).

Manufacturers warn against keeping AdBlue bottles in your car because if they leak, they can cause water and corrosion damage.

How do I know when the AdBlue is running low?

When the fluid level in a diesel automobile drops below a specific level, a dashboard warning may appear, and the vehicle’s performance may be reduced after a given period of time. At 1500 miles, VW models display a warning message and sound an alarm.

Following warnings appear every 62 miles or so till the warning turns amber and the alarm is repeated every 31 miles around 1000 miles. If these warnings go unheeded, the warning message will turn red, and the car will not restart after being turned off. It will only restart after a top-up.

There isn’t a standard symbol for a warning. Mercedes utilizes a visual that looks like a fuel warning light, whereas Volkswagen uses an image of a bottle being poured. The sign “DEF level low” is displayed on Land Rovers.

What if I accidentally put AdBlue in the diesel fuel tank?

Even in cars where the AdBlue filler cap is near to the gasoline cap, it’s unlikely to happen because the two have distinct colors and use different-sized nozzles. However, if it does happen and you see it quickly, do not start the engine. If you do, the corrosive AdBlue will be pumped through the engine, costing you a lot of money in repairs or maybe requiring an engine replacement. To drain your fuel tank, you’ll need to hire a breakdown service.

What if I accidentally put diesel in the AdBlue tank?

This is made more difficult by the fact that a fuel nozzle should not fit within the AdBlue tube. If it does, do not start the engine since the AdBlue equipment may be damaged. In any case, you may need to change some AdBlue system components.

How much is AdBlue?

Small bottles are costly, and you’ll almost likely need more than one to fill up your car when the warning sign illuminates, but they do have a secure nozzle to minimize spills. £6.50 gets you a 1.9-litre bottle from Volkswagen. 1.5-litre bottles can be purchased for roughly £10 at some gas stations.

A funnel or spout is usually included with ten litre bottles to avoid spills, and they cost roughly £13.

What is AdBlue made of?

It’s a blend of demineralized water and ammonia, which is made from urea, which is mostly taken from cow urine – those with sensitive natures, turn away immediately.

In a process known as selective catalytic reduction, the chemical component breaks down harmful exhaust fumes (SCR).

What is SCR?

Selective Catalytic Reduction is a process that occurs in a diesel car’s exhaust system. AdBlue is injected into the exhaust emissions of a car, where it breaks down hazardous nitrogen oxides (NOx) into harmless water vapour and nitrogen.

Why is AdBlue used?

To reduce NOx emissions, which are connected to respiratory ailments and thousands of premature deaths each year.

New vehicles must comply with EU laws that set a maximum limit for NOx emissions. Since September 2015, when new Euro 6 laws went into effect, that restriction has been decreased.

Many manufacturers discovered that the only option to comply with these restrictions was to add an SCR system to their diesel vehicles, which emit more NOx than petrol vehicles.

How long will AdBlue last?

A typical mid-sized diesel automobile can go 1,000 kilometers (620 miles) on a single litre of AdBlue, according to GreenChem. Because most AdBlue tanks hold 10 litres or more, you might not need to top it up until your next scheduled servicing.

However, the number of kilometers travelled, driving style, and vehicle load all play a role. The payload of commercial trucks is another issue to consider.

If you need to top up AdBlue between services, the car will notify you via dashboard notifications in plenty of time. It will either tell you how far you can go before a top-up is required or how many times you may re-start the car, so check your handbook. Warning: If you don’t fill up AdBlue before it runs out, your car will not start.

Does AdBlue stop DPF problems?

As the gases flow through the filter, the soot trapped in the DPF begins to clog the filter. This system, however, is not a replacement for a DPF, as automobiles with AdBlue tanks will always have a DPF as part of the overall emissions control system.

Why is there a shortage of AdBlue?

In December, a shortfall of the commodity forced the federal government to scramble for new suppliers, and a contract was struck with local fertiliser firm Incitec Pivot Limited (IPL) to boost output in Queensland.

Supplies in Australia were dangerously low, prompting fears that trucks would be stranded, but Energy Minister Angus Taylor said inventories were already being replenished.

“Last week, Incitec Pivot accomplished a key milestone by generating over three million litres of AdBlue in a single week, accounting for around 75% of Australia’s AdBlue demands,” he said in a statement.

“This locally made AdBlue is already making its way across the country’s domestic supply chain to wholesalers and service stations.”

IPL managing director Jeanne Johns said the 3 million figure represented an 800 percent increase over what the firm produced in early December, and that the Gibson Island plant in Brisbane was now open 24 hours a day, seven days a week.

“We’ll keep working hard to enhance AdBlue production at Gibson Island in the coming weeks and months to fulfill Australia’s demands,” Ms Johns said in a statement.

AdBlue is a urea-based diesel exhaust fluid that serves as an anti-pollutant in diesel engines and is essential to the freight and logistics industries.
