Let me clear this up
- It is legal to run your vehicle on chip fat up to 2,500 ltrs per year, you are told to keep a log but very few do.
- It is legal to run on any mixture of liquids when they are "Fuel duty" tax paid, Vat is not the issue, fuel duty is on any liquid fuel used to propel a vehicle (X pence per litre)
- If you run on new chip fat , you "should" declare as you buy it that is is not for food use and pay VAT but no chance of being caught for that.
- Mixing whte spirit or other thinning product is technically not legal because fuel duty is not paid on the white spirit, but if you thin with petrol you are clear.
- Running on the red stuff or heating oil you run the risk of loosing yer vehicle, on chip fat you do not 4 sure up to 2,500 litres and the dipping guy ent gona ask for your litre count log. Will he care if you have mixed it with a thinning product, prob not, but frankly petrol works fine.
- last time i was dipped, he did'nt even spot the 2nd tank with fat in it, but he did spot the smell of fat in the tank cos on change over the return du,ps some fat in the diesel tank.
Not a lawer, just love my sII enough to want to be sure no gov storm trooper takes it from me, or tries.
