As the use of AdBlue® becomes more widespread, it’s essential for drivers to understand its maintenance requirements to keep their vehicles running smoothly and in compliance with emission standards. This article covers everything you need to know about AdBlue® maintenance, including the types of vehicles that use it, refilling best practices, and potential consequences of misuse.
Understanding Vehicles that Use AdBlue®
AdBlue® is typically used in diesel vehicles equipped with SCR systems. This includes a broad range of vehicles, from passenger cars to heavy-duty trucks and buses. The primary function of AdBlue® is to break down NOx emissions into harmless nitrogen and water vapor, significantly reducing the vehicle’s environmental footprint. While most new diesel vehicles in Europe, and many other parts of the world, now come with SCR systems, it’s crucial for owners to know if their vehicle requires AdBlue®.
- Commercial Vehicles: Heavy-duty vehicles, including trucks, buses, and some agricultural machinery, are required to use AdBlue® to meet stringent emissions standards.
- Non-road Mobile Machinery: This includes construction equipment and other off-road vehicles that must comply with Euro VI or equivalent emission standards.
- Passenger Cars: Many diesel passenger cars manufactured in recent years, particularly outside Indonesia, in example models from European automakers, come with SCR technology and thus use AdBlue®.
If you’re unsure whether your vehicle uses AdBlue®, check the owner’s manual or consult with your vehicle manufacturer.
AdBlue® Refilling: When, Where, and How to Do It Right
Refilling AdBlue® is an integral part of maintaining vehicles equipped with SCR systems. Running out of AdBlue® can cause your vehicle to enter a “limp mode,” significantly reducing power and speed, or prevent it from starting altogether. To avoid these inconveniences, follow these tips on when, where, and how to refill AdBlue® correctly.
- When to Refill
- Dashboard Warning Lights: Most vehicles will alert you when the AdBlue® level is low. Typically, you’ll have a range of a few hundred kilometers after the initial warning, giving you time to find a refill location.
- Regular Maintenance: If your vehicle has high mileage or is used for heavy-duty purposes, check AdBlue® levels more frequently. A routine check during every oil change is a good practice.
- Where to Refill
- Fuel Stations: Several fuel stations, especially on major routes or industrial area, have AdBlue® refill pumps for heavy-duty vehicles
- Dealerships and Service Centers: If you’re unsure about the refilling process, it’s best to visit a dealership or an authorized service center.
- DIY Refills: AdBlue® is also available in bottles and containers of various sizes, allowing for easy refills at your own place. Ensure that the container is sealed, clean, and stored away from direct sunlight.
- How to Refill
- Locate the AdBlue® filler cap, which is often blue and located near the fuel filler cap or in the vehicle’s trunk.
- Pour AdBlue® carefully using a funnel or a specialized pouring spout to avoid spillage.
- Do not overfill—stop once the AdBlue® level reaches the recommended capacity.

Maintenance Tips to Keep the SCR System Running Smoothly
To ensure the efficiency and longevity of your SCR system, regular maintenance and proper handling of AdBlue® are crucial. Here are some maintenance tips:
- Use Only Genuine AdBlue®: AdBlue® is a specific mixture of urea and deionized water. Using non-approved solutions can damage the SCR system.
- Check for Contamination: Always ensure that the AdBlue® you’re using is free from contaminants. Even a small amount of dirt or impurities can damage the SCR catalyst and other components.
- Store AdBlue® Properly: AdBlue® should be stored in a cool, dry place. Avoid exposing it to direct sunlight, as this can cause the solution to degrade.
- Regularly Check SCR Components: Ensure that the SCR catalyst, injectors, and other components are in good condition during every service interval to prevent costly repairs.
Misuse and Its Consequences: What Happens If You Run Out of AdBlue®?
Running out of AdBlue® or using an incorrect solution can have severe consequences for both your vehicle and the environment. When your vehicle’s AdBlue® level runs out, it will enter a fail-safe mode to limit further emissions, which usually restricts speed and power. If the AdBlue® tank is empty, some vehicles will not restart until the tank is refilled. This is to ensure compliance with emissions regulations. Using the wrong fluid can cause irreversible damage to the SCR system. For instance:
- Water: Water lacks the chemical properties needed to reduce NOx emissions and will lead to increased emissions and potential fines.
- Diesel or Other Fluids: Introducing any other fluid into the AdBlue® tank can clog injectors, damage the SCR catalyst, and lead to costly repairs. If you accidentally use the wrong liquid, do not start the vehicle. Drain the AdBlue® tank and flush the system immediately to prevent further damage.
Proper maintenance of your vehicle’s AdBlue® system is essential for optimal performance and compliance with emissions standards. By understanding which vehicles use AdBlue®, following best practices for refilling, and avoiding misuse, you can ensure that your vehicle remains environmentally friendly and efficient on the road. For any uncertainties or issues, always refer to your vehicle’s manual or consult with a professional.
