B - Biodiesel
Biodiesel - Biodiesel is recycled from organic oils and fats rather than being refined from oil pumped from the ground. Its major advantage is that it is more environmentally friendly than normal diesel because it emits no additional carbon dioxide - just the carbon dioxide originally absorbed from the air by the plants or animals it's made from.
Most diesel cars are able run on biodiesel, but you should consult your dealer first. Using this fuel without doing so could invalidate your warranty. To find the nearest fuel station selling biodiesel, log on to biodieselfillingstations.co.uk.
