None of us are fans of the oil companies--or the environmental consequences of extracting fossil fuel and  then burning it...bio diesel is one option and one that I have chosen. Its cheaper than mineral diesel (regular diesel which is £1.30 ++ per litre at present), does not leave toxic fumes and makes one pleased not to pay money to Shells ane Exxons of this world.

If you have a regular diesel car you can usually pour the biodiesel straight into the tank with no modification. Most of the German diesel engines; VW, Audi, Mercedes are no problem--and check websites for those which need modification.  Companies like Greenfuels listed below, go around London and pick up frying oil from chippies and kebab shops, filter it and sell it on. However the government now taxes this and biodiesel has gone up from .88 per litre two months ago to around £1.10 a litre. But if you believe in recycling and are near one of the biodiesel stations, try it.  I usually keep the mixture to 75% bio and 25% mineral diesel.

Sometimes I simply buy vegetable oil from the supermarket--which has also gone up recently in line with rising food prices. Having checked out prices in Sainsbury, Tesco and Coop, I found to my surprise that the cheapest is Waitrose at .95 pence a litre for vegetable oil.  However this raises the ethical question of whether crops should be grown for fuel rather than food (discussed in the BBC link below I include). Good question--so I keep several litres of veg oil in my boot for top ups and try to use recycled frying oil the rest of the time.  Unlike keeping litres of mineral diesel in your boot, you will not go up in flames if somebody rear ends up...Another positive is that I seem to be getting better milege with biodiesel as well.

Many UK commercial fleets now run on biodiesel and find it more economic. They have installed heaters in their engines to keep the oil flowing when the temperature falls below 12C--for the rest of us, biodiesel is a summertime option. If you want to use it all year, get an engine heater installed.  All this can be found on various websites.

And remember; for years ordinary German & French drivers have been using recycled frying oil in their diesels. The majority of people there run diesel not petrol engines--which get much better mileage by the way, and are now very clean engines. All my German friends are amazed that it is only a minority in the UK on biofuel.

The product in the ECO fuel saving (post)seriously reduces CO2 and  also increases mpg so it is a win win win situation ECOMAN

I think there's a business opportunity here for someone to get in touch with restaurants and, particularly, chip shops around the country and arrange to collect their used oil. They would then purify it and sell it on to car drivers. Maybe someone is already doing this?
