AdBlue: What is it and why do we use it?

We have implemented a Selective Catalytic Reduction (SCR) system, which requires AdBlue, in all 2016 Toyota Hilux and Proace models, as well as 2016 Toyota Land Cruisers powered by the new 2.8-litre diesel engine.

An SCR system works by injecting AdBlue into the exhaust gas to generate ammonia, which reacts with the NOx on the SCR catalyst to generate nitrogen and water. Use of Toyota’s compact, high-dispersion urea SCR system eliminates up to 99 per cent of NOx emissions, one of the main causes of air pollution. This helps vehicles conform to the latest Euro 6 emissions regulations.

AdBlue is the commercial name of a diesel emissions additive fluid consumed in the process of driving. Due to the SCR system, the AdBlue tank may sometimes need to be topped up between services.

After a full refill, a car can be driven for approximately 9,000 miles before the supply of AdBlue runs out. However, this is dependent on driving conditions and style.

When AdBlue level is low

Always pay proper attention to the warning system if you are notified of low AdBlue levels. If your vehicle needs additional AdBlue, your instrument panel will begin warning you with sound and detailed instructions when 1,500 miles, 500 miles, and limited miles remain.

Here’s how the warning system works:

  • Low level warning at 1,500 miles
  • Second low level warning at 500 miles – the warning buzzer will sound and, if the displayed driving distance is exceeded, the engine cannot be restarted
  • Third low level warning when tank is empty – the warning buzzer will sound. If the engine is stopped, it cannot be restarted

AdBlue refilling guidelines

AdBlue is highly corrosive and should be handled with extreme caution. If accidentally spilled, it will cause damage to anything it touches. We recommend having your tank refilled at an authorised Toyota dealer.

If you need to refill the AdBlue tank yourself, in case of emergency, instructions are available in your owners’ manual. The tank is normally hidden within the body structure and the filler outlet is located within easy access – often in the engine bay or within the vehicle’s offside B-pillar, accessible when the driver’s door is open.

Although it is required much less frequently, having your AdBlue tank refilled is as necessary as refuelling your car. Your engine will not start without it. AdBlue solution is available for purchase from a variety of sources, including your local Toyota dealer, and some fuel stations may even have AdBlue dispensing points.

The price for an AdBlue refill bottle is £14.50* (including VAT), excluding any dealer labour cost. You can find your local Toyota dealer here.

    1. Hi Trevor,
      Thanks for getting in touch.
      It greatly depends on the mileage as well as the driving conditions.
      The adblue is held in a special tank with a capacity of about 22 litres, this provides a driving range of about 12,500 miles (20,000km), after which an alert is triggered warning you when the reserve remaining is enough for just 1,500 miles (2,400km).
      If the estimated mileage between two services is greater than 12,500 miles (20,000 km), we recommend that you go to an authorized Toyota Centre or repairer, or another duly qualified and equipped professional to have the necessary top-up carried out.
      We hope this helps.

    1. Hi Yusuf,

      Thanks for getting in touch. The DTC provided appears to be too short. However, the vehicle should still be within warranty if it is less than 5 years old, so we would advise for you to contact your local Toyota Centre for diagnosis and investigation.

  3. hi everybody i have a question i just took hilux 2019 and in 7100 km i consumed 12 liters of adblue can you help me understand if it is normal or there is a problem, i checked if there are leaks but they are not seen

  4. Hi guys,
    A friend of me have hilux 2017 and the cost of Adblue is about 200 USD, a cost of about 350 lt of fuel. The cost is a bit expensive. Do you think the need for adblue can be disabled by computer in a country where the requirement is not an obligation. Regardless of the advantage.

    1. Hi Amanuel,

  5. Hello, I have a 2020 Toyota Hilux with a 2.4L 2GD engine. I refilled a 10 Liter adblue fluid at around 6000km and now the warning light is on again. The car now is at around 9800KM and the message says 1050km remaining. I am assuming it has a very high consumption. I used Total AdBlue with “SCR Technology”, I don’t know what this means. Is the consumption right?
