This AdBlue guide will include everything you need to know when it comes to purchasing AdBlue using Fuelwise Fuel Cards.

AdBlue Guide

What Is AdBlue?

AdBlue is a solution composed of deionized water and urea, both of which are non-toxic substances. This fluid is designed to be automatically injected into the exhaust system of your diesel vehicle, aiding in the reduction of harmful emissions.

What Is AdBlue Made Of?

AdBlue solution consists of a precise mixture of 32.5% urea and 67.5% de-ionized water. The urea component of AdBlue is derived by subjecting synthetic ammonia and carbon dioxide to heat. Subsequently, the resulting urea is combined with de-ionized water, resulting in the creation of AdBlue.

How Does AdBlue Work?

Upon being sprayed into the exhaust system, the AdBlue solution initiates a reaction with the nitrogen oxide gas generated during the combustion process. This reaction effectively transforms the harmful emissions into steam and nitrogen, thereby contributing to the reduction of pollutants.

How Do I Fill Up With AdBlue?

When it comes to purchasing AdBlue using a Fuelwise Fuel Card, the process is the exact same as purchasing diesel. Check out our guide on how to use a fuel card.

Some fuel stations will allow you to purchase jars of AdBlue using a fuel card, however, this is at the sites discretion and you should always check first.

Where Can I Fill Up With AdBlue?

You can purchase AdBlue at any fuel station on the Fuelwise Fuel Card Site Network that provides AdBlue as a product option.

At the time of writing in June 2023, there are 1,164 fuel stations that provide AdBlue.

You can filter your search and view only sites that provide AdBlue when using our online site locator or mobile app.

Can I Buy AdBlue With My Fuel Card?

Yes, all fuel cards that have Diesel as a product option automatically include AdBlue.

“Fuelwise is very customer focused and were able to provide what I needed for this project where others couldn’t. The e- Route app helps our engineers find Core sites instead of Non-Core sites which helps with efficiencies and cost savings. Velocity is well managed, and I can create plenty of reports and my Account Manager is always on hand to help. With GPS Tracking built into Velocity I can view distance travelled, speed etc. and driver contact details without having to open another system.”
