Diesel Exhaust Liquid Specialists

Road Transport

busDuring the past few years, emission standards in passenger carrying vehicles such as Coaches, Buses and Mini Buses have become more stringent, with diesel engine manufactures using Selective Catalytic Reduction (SCR) to reduce harmful exhaust emissions and pollutants.

Optiblue produces Diesel Exhaust Fuel (DEF) which meets ISO standards and is safe to use in all passenger vehicles. DEF is filled into a dedicated DEF tank fitted to the diesel bus to comply with the latest emission standards.


IMG_0208With local knowledge of the Australian transport industry, Optiblue is able to not only provide you with your Diesel Exhaust Fluid (DEF) needs and we can also consult with you to ensure you are achieving optimum results.

Optiblue DEF is regularly independently tested by certified laboratories to ensure you are receiving a high quality product. This ensure the vehicle’s manufacturer’s warranty is complied with.

We can deliver DEF in bulk quantities to your depot and have various dispensing pumps for sale to assist you with re-fuelling your DEF tanks.
