BTW lads it seems like you can use Veggie oil in your cars !

Tax and legal issues
It is not illegal to use vegetable oil as fuel in the UK.
Stop press! The rules changed on 01 July 2007. They used to be cumbersome and require that small producers (home users are just very small producers) register and submit monthly returns. Now, if you use less than 2500 litres of oil a year, you don't have to register or pay duty!

Here are some links to look at if you are in doubt !

I have also been on the phone 3 times tonight asking about this issue and Customs have assured me it is 100% correct.

Do you just buy vegitable oil and pour it into the tank with the diesel?
Is any particular type of oil best such as sunflower oil?

I've been running on a 33% mix for months in a VW TDI engine. No problems at all. The engine is smoother, quieter and has a little more power. There's less smoke as well. I've never used waste oil but I'm told it tends to make your exhaust smell like whatever was cooked in it previously! I've used veg oil, corn oil and sunflower oil. All work well.
Veg oil is still the same price as when I started. Diesel has gone up about 10p a litre. 8)

I have spoken briefly today with a chap I know who makes about 2000 litres of bio diesel a day and he has advised me to check what injection system my car has because some of the computerised systems don't like bio diesel and clog up. Anyone know anything about this and what to look for. He can sell me 1000 litres for £250.

I think you need to ask your engines manufacturer i know some modern engines like the merc cdi engines the injectors run at very high pressures and can clog up very easily and at about £1200 for a set of injectors !!!!

In principle the idea is fine if your engine will adapt to it BUT what effect does it have on the engines efficiency and what sort of savings do you get it also strikes me that 2500 litres is quite a low limit on some of the mileages taxis do a year

Rapeseed.. or.. vegetable oil are the raw products...... they contain fats or soaps that have to be taken out.......... if you use the raw products even with a mixture of diesel the soaps will build up in your fuel tank.. fuel lines... fuel pumps.. even electric fuel pumps..... the more miles you do the quicker it will build up.. so it all depends on how many you do a year before you have problems..... Bio fuel.. made correctly is a good fuel...

If you get a electric pump and connect it to a filter . and then pass the raw product through it into your car ............ you'll find most of the rubbish taken out....

Steve, You are quite right regarding the fact that everybody is allowed to produce 2500 litres of biodiesel per year for personal use. If you take this to its logical conclusion , as far as I'm concerned, a family of four would legally be able to use 10,000 litres. 1 gallon equals 4.546 litres.

I am a diesel mechanic and have been (just for JD!) tinkering with the running of diesel vehicles on bio fuel and veg oil for the last two years. I have also been interested in the production of this fuel.

Vehicles which are run purely on vegetable oil tend to have fuel filter problems, continuously. Vehicles which are run on 50-50 mixes still have problems, but which don't appear for a longer period of time.

Vegetable oil or bio diesel degrades rubber connections which should be replaced with plastic, if not, they either leak or degrade into the fuel system.

The vehicles which run best on it are those which have a fuel pump and injectors. Anything which runs on a common rail system tends to fur (block/grease) up as time goes on. It leaves a residue similar to hand cleaner in consistency........ fuel pumps which are electronically controlled can go ape at any time when run on pure vegetable oil.

Bio diesel is made by mixing chemicals with the raw product, whether it be virgin or used waste oil. It is then heated. It is then mixed with water which binds with the chemicals that have been added and the fats these chemicals collected. It is then left to separate, bio fuel on the top, water and chemicals on the bottom. The water is then removed. The bio fuel is then reheated - boiled near enough - to remove any residue of water remaining in its molecular structure. The finished product is then filtered by a 1 micron filter.

I find the best way to use bio diesel is to use it as a mix of 4 parts bio to 1 part diesel ............Trevor
