Why is it illegal to run a diesel engine on chip oil?

in uk you can use up to 2500 litres per year tax free but you have to keep a milage record. thats it. nothing illegal about it.

It is not illegal unless you use over a certain limit.

This was because it was actually costing more in admin to process the tax than the value of the tax collected. Therefore the treasury set a limit - anything over domestic use (running a taxe for example) would likely put you over the limit, and you will be expected to pay tax. You also need to keep receipts to make sure you register before you are likely to go over limit.

This is somewhat of a break to the green consumer, and the government expect it to catch on - that way they CAN tax it again when it's popular (like they did with diesel fuel) - and is what's happened in Germany.

It actually has better lubricity for engines - so a 5% blend will soon be mandatory in all diesels. Unfortunately for the consumer, it can therefore be labeled "biofuel" because it contains some - thus is a wolf in green sheep clothing.

Higher percentages-over 50% can cause problems with injector pumps, and clouding at low temperatures, therefore needs engine modification.

Look to the US for lots of information - as they are well into the scene now.

In most places there is a tax on diesel fuel (and petrol/gasoline). The tax usually pays for roads and/or other government services. When you buy diesel, the tax is part of the price of the fuel. It is illegal to avoid paying the tax.

Some jurisdictions have set up a process that allows people to send in a payment for the tax on homemade fuel. If the correct tax is paid, then it is probably legal to run your diesel vehicle on used chip (french fry) oil. Just be sure to filter it well so it doesn't clog your fuel lines.

It is NOT illegal to run a diesel engine on chip oil... Why do people think it is?

I do it and it's quite legal. Vegetable oil is classed as a biofuel and as long as you don't use more than 2,500 litres per year, you don't have to pay duty on it. More than that, you must paythe required duty of 28p per litre to HMRC

FAO Torry_Stiles.. Veg oil is a zero carbon footprint because, by growing crops to produce the oil, CO2 is absorbed by the crop and released by burning it in an engine, therefore there is no net increase in carbon in the atmosphere.

Making Your Own Diesel

it is legal in the UK to run a diesel car on chip oil in the UK.

Low Impact Living Initiative run courses giving you all the tecnical and legal/tax know-how

http://www.lowimpact.org/courseoutlinebiodiesel.ht...

Also companies like Sharwoods & Macdonalds are using their oils oil for vehicles.

It has never been illegal in the UK to make your own electric, or gas either. but you should be qualified so as not to be a danger to yourself or others.

It took me a while to figure out you're talking about vegetable oil used to cook ... such as to cook "chips" or "fries."

It's do-able and has been done but I'm curious... Why do you say that it leaves no carbon footprint? It still must be burned and thus release carbon dioxide to the atmosphere.

It's not illegal ,and you dont have to pay any tax if you use less than 2500 litres a year ,thats 50 litres a week ,which is about what normal people use on average.

There is a tax to be paid on it ,if u drive it on the roads. That is the source for the money to build roads. If u check it out u will find that if the motor does the same work it will produce the same CO2.

It's not illegal as long as you pay the taxes, you need to pay both state and federal "road" tax. This tax is supposed to be used to keep up the roads but in most cases it goes to the general fund and very little goes back to the roads.

I have never heard of chip oil. Is there another name for it? Where (in what country) is it illegal? And, are you sure it it illegal? Have you researched this or is it Just hearsay? I would check government sources in your country. If it is illogical, it probably isn't happening or you may not have enough information.
