Do I need to have my car modified?

No.  Some cars prefer a blend of biodiesel and normal diesel, but by and large you can just fill up and drive.

Will I notice any differences?

Probably not. Fuel consumption is about the same, you may notice that your engine is a fraction quieter. Some people find that cold starting is a bit slower but it runs fine when it's warmed up a bit.

Do I need to take any precautions?

Biodiesel is a better solvent than normal diesel, so in older vehicles there is a chance that deposits in your fuel system will get dissolved out and end up in your fuel filter. We've never known anyone have a problem but it's wise to check after you've been running biodiesel for a while.

Will my car smell of chips?

Sometimes when you start a cold engine you will get a smell of frying for a few seconds until the exhaust warms up. After that  you probably won't be able to smell anything.

Can I mix biodiesel with normal diesel?

Yes.

Why is it cheaper than normal diesel?

Because the fuel duty is less:- 27.1p/litre instead of 47.1p/litre.

Will it affect the life of my engine?

Biodiesel is a better lubricant than normal diesel, also it does not contain sulphur or other corrosive components like petroleum diesel does. Most people who have been running biodiesel for a long time report much reduced engine wear. There are horror stories around but they can normally be traced to badly made fuel. All of our biodiesel conforms to the appropriate EC standards.

Are there any problems in the winter?

Biodiesel has a higher gelling temperature than petroleum diesel which means that it could gel in cold weather. The solution is to mix a little petroleum diesel in your tank or use the special winterising additive that we sell. We can advise you how much of either you need to use.
