AI Overview
is a colorless, high-purity aqueous urea solution (32.5% urea, 67.5% demineralized water) designed for modern diesel vehicles to reduce Nitrogen Oxide (NOx) emissions, making it essential for Selective Catalytic Reduction (SCR) systems. It is crucial for meeting Euro 4, 5, and 6 emissions standards, preventing the vehicle from entering "limp mode" (limited power) if the supply is exhausted.
Key Information & Benefits
- Application: Injected directly into the exhaust system, it breaks down NOx emissions into harmless nitrogen and water.
- Compatibility: Used in diesel cars, trucks, buses, and tractors with SCR technology.
- Consumption: Typically 2-8% of diesel consumption volume, requiring infrequent refills.
- Specifications: Complies with DIN 70070 and ISO 22241 standards.
- Storage: Must be stored in a separate, often blue-capped tank.
Purchase Options & Examples
- Mannol AdBlue 10L: Approximately 22.38USD for 10 litres, often supplied with a spout, featuring DIN 70070 compliance.
- Carlube AdBlue 10L: Listed at around 52.17USD from Simply Bearings.
- Mannol 20L Canister: Roughly 40.91USD for 20 liters on eBay.
- : Available for 8.88USD at Walmart.
Usage Notes: Do not put AdBlue in the diesel tank; it is not a fuel additive. It should be kept in a cool place and typically has a shelf life of around 12 months.
For the best maintenance, I recommend looking into specialized no-drip pouring spouts to avoid potential corrosive spills on your car's paintwork. Do you need help finding the location of your AdBlue tank, or perhaps advice on local retailers near you?

Does it matter which AdBlue I use?
That said, make sure you buy the correct AdBlue for cars, with the label ISO 22241 (including ISO-22241-1, ISO-22241-2 or ISO-22241-3) which will ensure it doesn't damage the catalytic converter in your car's exhaust – an expensive component to fix.Jun 7, 2024
