red diesel is no different to normal, apart from the colour to identify the lower tax rating for use off road, agriculrure and plant etc

They fill up at the refinary, guy goes along the top of the tanker, throws in a bit of dye into ones that need to be red, diesel now red, customs man checks them when they leave. Sorted... same diesel...

heres an extract i found from an article on a merc web site.

Just a technical point here on the subject of red diesel.
There is a difference between it and Derv. Red diesel is actually dyed gas oil, whereas Derv is a more refined petroleum distillate. There is a difference both in the specific gravity and the calorific value of the two, making the Derv a more refined and cleaner product. Putting the legal issue aside here, Red will run ok in an engine, albeit a little more smokily and will probably do no long term damage other than dirty up the injectors quicker and possibly cause a little more carbon build up in the engine, as Red does not have the additives that your average " city diesel" at the forecourt has.
