| Bio diesel sounds like a great idea but there is not enough - nowhere near enough - oil to meet present demand. I used to make it for my Audi but I have been unable to get the oil from previously reliable sources. There are lots of people trying to make bio diesel at the moment who don't know what they are doing and are likely to knacker their engine.
The environmental cost of using virgin vegetable oil has been mentioned earlier in the thread and means that I won't do that. Incidently the cost of virgin vegetable oil has gone up about 75% over the last year due to bio fuel production.
If people want to save money on fuel think about how you drive - easier on the right foot is easier on the pocket - do you really need the air con on all of the time - could yo use puvlic transport / or share the driving - do you need to make the journey could you walk / cycle?
The above is the not answer for everyone I realise but if you live in a city then there really are options much of the time. |
