What types of diesel cars require AdBlue?

Today, AdBlue (Diesel Exhaust Fluid, DEF) is becoming increasingly common in diesel vehicles that comply with Euro 5 and Euro 6 standards. These include a wide range of vehicle types such as passenger cars, SUVs, pickup trucks, trucks, buses, and even heavy machinery.

In many modern diesel models designed to meet Euro 5 and Euro 6 regulations, an exhaust after-treatment system is installed to reduce harmful emissions produced during diesel combustion. Diesel exhaust gases contain nitrogen oxides (NOx), which contribute significantly to environmental pollution if released untreated into the atmosphere.

This treatment system is known as Selective Catalytic Reduction (SCR). Within the SCR system, AdBlue must be injected to react with nitrogen oxides (NOx), converting them into harmless nitrogen (N₂) and water vapor (H₂O)—both natural components of the air we breathe.

Diesel Vehicles in Thailand

In Thailand, diesel vehicles come in a wide range of brands and models. Some of these are equipped with Selective Catalytic Reduction (SCR) systems, which require the use of AdBlue, particularly in new-generation diesel vehicles manufactured from 2024 onward.

Examples of diesel vehicles in Thailand, categorized by type of use, include:

• Passenger Cars e.g. Mercedes Benz c220d , BMW
• Pickup Trucks e.g. Ford Ranger, Toyota Hilux
• SUVs e.g. Ford Everest , Toyota Landcruiser
• Buses and Trucks e.g. UD , Scania , Hino

For accuracy and reliability, vehicle owners or drivers should confirm whether their diesel vehicle requires AdBlue by:

• Checking the owner’s manual provided with the vehicle
• Inspecting whether there is a separate AdBlue filler cap, usually located apart from the diesel fuel tank
• Consulting with a certified service center or authorized dealer of the vehicle brand

By following these steps, you can determine with certainty whether your vehicle requires AdBlue.

Where to Buy or Refill AdBlue

You can refill AdBlue at the authorized service centers of your vehicle brand.
