I was just reading www.bio-power.co.uk, when something occurred to me.
When the C&E people do spot checks for red diesel, they presumably syphon a bit out of the fuel filler. They don't take the fuel from the fuel line in the engine bay.
I know that some veggie oil users have two tanks, so they can start on petrodiesel and switch over to vegetable oil once running.
So, presumably you could keep your regular tank with a few gallons of petrodiesel in it, and then have a second tank (in the boot?) full of red or veggie oil... this one you really use.
Surely C&E don't have the right to search your vehicle so provided you let them take a sample from the filler cap then you wouldn't have any trouble.
