what dye is used in red diesel?

Answer 1

it's to determine if it's tax exempt, it's a big fine if you get caught using it on the road, did you mean what or why :(

Answer 2

It's not a food dye, it's a dye called Solvent Red 24 and it always leaves traces even if you think you've filtered it out somehow.

In the United Kingdom the "red diesel", gas oil for heating and plant use, is significantly cheaper than heavier-taxed diesel fuel, but it is a different fraction, containing more sulphur. Using it in modern high-tech diesel engines is therefore damaging, to your engine, the planet and your wallet if HMR&C catch you!

Answer 3

A special dye which has chemical tracers in it so that even if the dye is filtered out using fullers earth etc it can still be proven to be duty free if you get dipped by the customs people.

Answer 4

Red dye I would imagine, but there is something else in there because if you get stopped, they litmus test your fuel (remember litmus paper from Chemistry lessons at school?) So depending what colour the litmus paper goes they can tell what is in your tank

Answer 5

Heating oil, or oilheat, also known in the United States as No. 2 fuel oil and elsewhere as "red diesel", is a low viscosity, flammable liquid petroleum product used to fuel building furnaces or ("boilers").
Heating oil is usually colored by addition of fuel dyes to distinguish it from highly taxed road-use diesel. Red dyes are usually used, resulting in its "red diesel" name in countries like United Kingdom. Solvent Yellow 124 is added as a "Euromarker" since 2002 in European Union.

Fuel dyes are dyes added to fuels, as in some countries it is required by law to dye a low-tax fuel to deter its use in applications intended for higher-taxed ones. Untaxed fuels are referred to as "dyed", while taxed ones are called "clear".

For example, in United Kingdom the "red diesel", gas oil for heating, is significantly cheaper than heavier-taxed diesel fuel, but it is a different fraction, containing more sulfur. Using it in diesel engines is therefore damaging both to the environment and to the tax collectors, therefore the authorities want it deterred; addition of a dye is one of the methods.

The dyes used have to be soluble in hydrocarbon-based nonpolar solvents ("solvent dyes"), and therefore in the fuels they are added to. Red dyes are often various diazo dyes, eg. Solvent Red 19, Solvent Red 24, and Solvent Red 26. Anthraquinone dyes are used for green and blue shades, eg. Solvent Green 33, Solvent Blue 35 and Solvent Blue 26.
