As far as i'm aware you can run your diesel on vegatable oil without modification although i heard that it will run better on used oil. Supposedly it is not very good for the engine but I can't see what damage it will do. I would not however recomend it's used in a modern turbo diesel since these are very complex engines and costly to repair if it does go wrong. However if you have an old diesel van give it a go. As for the tax issue, it is illegal to run a car on any fuel that has not had the duty paid on it. There would be no point in trying to pay the duty as it would make your cooking oil no cheaper than regular diesel. I have attached a link that may be usefull.
Great idea this, but what most people forget is that used oil is not waste, it's supposed to be returned for cleaning and re-use.
Ok so this is only applicable to commercial users and yes they do have to pay for the waste oil to be collected, but in the long term it saves on production of new oils.
If everybody starts using chip oil in their cars, the commercial users will have to pay higher prices for new oil rather than using recycled oil and that will put up the price of any fried food you buy.
I've been running cars on waste vegetable oil for four years and am currently testing for my company running buses on waste vegetable oil. There are a couple of ways you can do this. 1. buy a conversion kit for your diesel car/truck/tractor/boat that heats the oil before it enters the injector pump (see greasecar.com) 2. blend the waste oil to reduce the viscosity and pour it directly into your main tank (see dieselsecret.com) 3. blend the waste oil in your main tank with a high percentage of diesel fuel. The KEY to all three is pre-filtration of very good quality waste oil. Your ideal oil should 1. come from the frier and not a dumpster 2. have very little water contamination 3. not have been filtered and reused by the restaurant too often. You must pre-filter the oil which is a very simple process of running the oil through a standard restaurant sock filter of 5 microns or less. If you live in a cold climate you may have to heat the oil first to get it to flow smoothly through the sock filter. You can find sock filters at the greasecar website or do some searching for canister filters. They cost about $3 per filter and I get 100 gallons or so through one.
The result: I get about 35 mpg on very good quality waste vegetable oil. The emissions are far less than diesel and of course there's not sulfer emissions. Since I use the greasecar system, I go 3000 miles between diesel fillups because I also cut my main tank with WVO. I have saved thousands of dollars over the past four years and have put that money back into my local economy (restaurants, buying things at stores, etc) instead of giving the money to big oil.
You don't if you have half a brain! OK with the old long stroke sloggers of days of yore but modern high speed diesels are pretty sophisticated engines and diesel fuels have a number of highly desire able additives in them.
Certain cars wont run on it! If you are thinking of doing it do a bit of research first. If your car is newer than 2006 then it probably wont, but older diesels can, either entirely on veg oil or as a mixture up to 50%.
And your car will smell like a used chip pan first thing in the morning!

My mate simply puts used chip fat straight into his tank - doesn;t run quite as well as biodiesel, but it is refined enough to work.

Good luck!

You add a conversion package to the engine. Cost is just under $1000.

hope this helps
You make what is called 'biodiesel'. It's a process of refining the oil and making it 'burnable' by the engine.
Search for 'biodiesel'.
