Diesel Defender​

Diesel Defender is a liquid anti-theft marker dye for UK non-rebated fuel, also known as white diesel, road diesel or DERV. The liquid blue dye colours white diesel to produce a green fuel and acts as a powerful deterrent to thieves.

It can be used in a wide range of applications, including construction equipment, cooling or heating units in road and rail transport, airport vehicles, forklift trucks, electricity generation and heating for commercial premises.


What is DERV?

DERV (Diesel Engine Road Vehicle) is a liquid fuel product that is used to power road vehicles. The fuel is also known as white diesel or road diesel and can technically be used in any diesel-powered engine, but is more commonly used in lorries, HGVs (Heavy Goods Vehicles), LCVs (Light Commercial Vehicles), vans, trains, buses and coaches. DERV is typically used in businesses with vehicle fleets who need to transport passengers and goods over both long and short distances.

Unlike other industry fuels that are rebated to help with business costs, government duty tax applies to DERV fuel.


What other names is DERV known by?

DERV has a variety of names, including:

  • Diesel
  • Road diesel
  • Road DERV
  • White diesel
  • Ultra-low sulphur diesel (ULSD)

All of the above fuels are the same, but DERV is the more formal name for the fuel.

How much is DERV?
