Im looking at replacing my everyday car with a diesel soon and am quite interested in running it on biodiesel. Especially now there is no tax on the first 2500 litres you produce / use.

I've seen a starter kit for home use which produces 40 Litres per batch (takes about 8 hours to process).

Does anyone make their own? Any tips on good places to get the oil / caustic soda / methanol.
