You should familiarise yourself with your vehicle's fuel type and refuelling procedures before driving the vehicle.

Information about the correct fuel type, including biofuels, can be found in the vehicle owner's handbook, on the fuel tank cap or the inside of the fuel cap cover.

Most of QFleet's vehicles are passenger and light commercial models. While the number of battery-electric vehicles is increasing, most of the fleet is fuelled with petrol or diesel.

Petrol-fuelled vehicles

All compatible Queensland Government petrol vehicles are to be refuelled using E10 where it is practical to do so.

It is deemed to be practical to use E10:

  • if the vehicle is compatible with E10, and
  • E10 is available at the service station where the fuel is intended to be purchased or at a suitable alternative service station.

Read the government's policy on the use of E10 (PDF, 405.1KB) to learn more.

Use the E10 OK Fuel finder to locate the nearest E10 service station when on the road or preparing for your journey.

Diesel-fuelled vehicles

Refuel compatible QFleet motor vehicles with diesel available from service stations.

Queensland Government diesel vehicles are not subject to a government biofuel requirement.

B5 diesel

Under national fuel standards, B5 (a biofuel blend containing up to 5% biodiesel) is considered compatible with all diesel engines and can be sold unlabeled in Australia.

B10 diesel

Only a limited number of QFleet vehicles can be refuelled with B10 (a biofuel blend containing 10% biodiesel). This fuel is not yet widely available, not compatible with all diesel engines and must be labeled at the bowser.

AdBlue (Diesel exhaust fluid)

Adblue, also known as diesel exhaust fluid, is not a fuel but an additive stored in a separate tank to your vehicles' diesel tank. It is sprayed into the exhaust stream when the engine is running. If your vehicle requires an AdBlue top-up, do not attempt to refill the vehicle yourself. Please contact the nearest vehicle manufacturer dealership for AdBlue to be refilled.


It is important to use the right type of fuel in your fleet vehicle to avoid causing any damage.

Do not start your engine if you find you have used the wrong bowser when refuelling.
