Fuel duty, 27p or 47p?

[Newboy]

I did a search on 'duty form', looking for how to fill in the custom form cos I want to run my surf on veg oil mix with diesel.

I'm a little (understatement of the year) lost as to what would net me the 27p tax and which one on 47p.

On one thread, it states if I produce (mix it with other substances) and use (pour it into tank) biodiesel I get the 27p tax, but on another thread, states I will have to pour veg oil straight into the tank to get the 27p tax.

So, which is true?

if you state to customs that you mix veg wiv deisel then you get the 47p rate if you state on your form that your using veg oil....................just veg oil then youll get the 27p tax do not say i repeat do not say you are mixing the veg with diesel and you will be ok,,,,,,,,,,,,,, if you do this it will bring the higher tax
