exocet® Diesel Defender is a liquid anti-theft marker dye for UK non-rebated fuel, typically known as white diesel, roaddiesel or DERV.




Fuel economy in any system and in any equipment is largely achieved by maintaining that equipment at ‘factory settings’ or at its design parameters. Fuel additives that slow down or even stop the rate at which equipment ‘gets dirty’ or ‘fouls up’; all aid fuel economy. This may also be achieved by proper maintenance of the fuel in storage or by affecting its behaviour within the equipment.
