AdBlue is used to meet the Euro5 and Euro6 emission standards for diesel engines:
Important: AdBlue does not go into your disel tank. It goes into a separate tank.
What is AdBlue®?
AdBlue® consists of water and urea (also called carbamide). Urea is an organic compound and it is injected into exhaust gas to reduce the very harmful NOx emissions of the diesel engines.
It is stored in a separate tank on the vehicle and dosed automatically, as required by the amount of Nitrous Oxides (NOx) being produced by the engine, into the exhaust gas, as required. The exhaust gas and AdBlue® mixture pass through the SCR system where a chemical reaction converts harmful NOx to harmless nitrogen and water, which is dispersed from the end of the exhaust.
AdBlue® is non-toxic and safe to handle. It is not a fuel or a fuel additive and should only be used in the dedicated tank in your vehicle. It is refilled in a similar way to refuelling diesel.
AdBlue® on Tap:
The Glen Fuels Kilmacanogue depot has AdBlue® on tap at our drive-in pump. The pump is open to everyone during business hours Monday - Friday 08.30 - 1700 and Saturday 08.00 - 13.00. If you have a Glen Fuels account, you simply sign at the counter. If you have a Glen Fuels Fuel Card, present your card at the counter to
How to Top-Up:
The AdBlue® tank is generally located:
- Beside the fuel filling point. It will be a smaller filling cap.
- In the car boot/ trunk. Cap will have DEF identifier and should be the only fill point in this location.
- Under the car bonnet. Cap will have DEF identifier. Be careful not to fill into screenwash or other fill point
AdBlue® is essential for the cleansing and reduction of harmful emissions and is injected into the exhaust gases before they enter the atmosphere. It is stored safely within a separate tank on the vehicle, and is specifically measured and applied by spraying into the exhaust manifold, reacting with the gasses within it, creating the cleansing and catalytic effect. AdBlue® consumption is typically around 3% – 5% of the diesel consumption for a typical vehicle, dependent on weight and other relative factors.
