The prevention of theft of diesel that has had the tax paid is a major concern. One method of securing your fuel is to dye it a different colour.

Powder dyes

FastColours are able to offer a range of solvent powder dyes that can fulfil this role. The dyes are extremely pure (98%+ dye content). Typical application levels would be 10-100 ppm. The more dye you use, the stronger the colour will be.

The powdered dye requires pre-dissolving in fuel. Make a concentrated solution by dissolving a known weight into a small quantity of fuel and then add this solution to the bulk to achieve the desired shade. The dyes can be mixed together to produce many different colours.

Liquid dyes

FastColours offers the following products from John Hogg, the specialist in fuel markers.

Dyeguard Blue 79K

Gives a very distinctive blue colour and so acts as a visual deterrent. It is suitable for all types of fuel and is approved by HMRC. However, you must still inform HMRC that you have added this product to your fuel. Typical applications levels are between 25 and 100 ppm. 1 litre is enough for between 10,000 and 40,000 litres of fuel.

Dyeguard Black K

Gives a black colour that acts as a visual deterrent. It is suitable for all types of oils and lubricants, but it is essential that you test the product before committing to large volumes. It cannot be used in the United Kingdom in fuel/diesel/heating oil as it has not been approved by HMRC. For other countries you would need to check the local regulations.

Dyeguard Marker IG and Dyeguard Developer D3

These 2 products have been specially formulated to detect fuel and oil theft. Dyeguard Marker IG is completely colourless in fuel. The addition of Dyeguard Developer D3 changes the colour of the fuel to a strong green.

Due to the physical form of the Dyeguard range, it is only for general sale in UK. For other countries, please get in touch and we will be happy to advise further.

IF YOU ARE ADDING DYES TO DERV (DIESEL FUEL) AND PETROL YOU MUST INFORM HMRC. Please ensure you read the safety data sheet that comes with the product before using.
