I don't even have a diesel but as Red Diesel is about 56p per litre, what is the punishment if you are caught using it on a road car?
56p compared to 130p for white diesel. The court fine would have to be substancial.

Yep, there was frequently one set up at the entrance of the Blackwall Tunnel and more recently there have been a few along the main road between Rotherham and Doncaster.you have to be enormously unlucky to get caught by a dip test (Anyone ever seen one??)

It used to be the case that they only bothered with commercial vehicles, but i guess that could change with prices going the way they are.
It is a pretty heavy fine, and i think they can crush your car.
Having said that I'm absolutely certain that every deisel car owned by a farmer round here runs on red, you have to be enormously unlucky to get caught by a dip test (Anyone ever seen one??) and they have a legit use for the stuff so they are unlikely to get caught after being followed back by customs and excise.
Doesn't mean it's a good idea though![]()
It's not a police matter, it's customs and excise.
AFAIK it's not actually red anymore either, it has to be chemically tested to prove you're using "red" diesel..
Can you even easily dip a tank on a modern car?


How much money do you save by visiting petrol stations twice as often?
Whatever it is, it'll be negated by that trip to the petrol station and backIt's more of a question of how much less fuel do you burn not carrying another half a tank of petrol around surely?

This dip test, couldn't you fool them by having 2 tanks, one on show and one hidden in the other wing - filled from a nozzle under the boot carpet? Obviously require a bit of work but most farmers know their way round an engine.
