Topping up AdBlue®

As of the 1st January 2017, the use of AdBlue® became mandatory in all diesel fuelled vehicles. So if you own a diesel car that is less than 3 years old you will need to ensure your AdBlue is topped up.

If your vehicle runs out of AdBlue it may fail to start, or may only start in ‘limp mode’ so it’s important you know what to do when it’s ready for topping up.

What is AdBlue?

AdBlue® is the trademarked name for ‘ Diesel exhaust fluid ’ and is the term used most frequently in the automotive industry.

AdBlue is used in modern diesel engines to reduce the amount of harmful emissions released into the atmosphere. It is a clear liquid (surprisingly, it’s not usually blue!) that breaks down soot & unburnt fuel into water & nitrogen, ensuring diesel vehicles can be driven with minimal impact on the environment.

AdBlue is made up of 32.5% urea and 67.5% deionized water and is odourless and not toxic, although it’s best to wear gloves when you’re topping it up as it can be messy and  leave a powdery stain on fabric and surfaces. It can also corrode some metals and so must be used, stored and transported with care.

How often does AdBlue need topping up?

How often your AdBlue needs topping up will depend on the vehicle along with other factors such as driving style, mileage and driving conditions. If you do mainly motorway miles then your AdBlue probably won’t need refilling as often as for a driver who mainly uses their vehicle for short journeys or in a town centre. AdBlue tank sizes also vary between vehicles so some cars will require topping up more frequently.

You will get a notification on your dashboard when your AdBlue level is low which will alert you that it’s time for a refill.

How to top up your AdBlue

AdBlue is available to buy in most garages, petrol stations and supermarkets and topping it up is a fairly easy & straightforward process. All Eden Tyres & Servicing branches keep AdBlue in stock so if you’re unsure how to do it or would prefer for someone to do it for you just contact your local branch.

Locate your AdBlue tank

The first thing you’ll need to know is where the AdBlue filler cap is located on your vehicle. It’s most commonly found next to your diesel filler cap under the fuel flap. However, on some vehicles it’s located under the bonnet or in the boot; it will be clearly marked and is usually blue. If you’re not sure where it is, have a look in your vehicle handbook which will tell you exactly where it’s located.

Filling up your AdBlue

You will usually get a funnel with your AdBlue which will make filling up your AdBlue tank clean and easy. The size of the AdBlue tank varies from vehicle to vehicle so you will need to check your vehicle handbook first to know how much you’ll need.

Make sure that any spills or AdBlue on your hands is rinsed immediately as this could cause irritation and damage your car paintwork.

Remember, if you’re unsure how to fill your AdBlue or need some advice contact your local Eden Tyres & Servicing branch where the team will be happy to help.
