If you don’t have money to buy fuel for your diesel car or you just want to have a “green“, environment friendly car you can use biodiesel, instead of regular fuel bought from the petrol station.

“Biodiesel is a fuel similar (but not identical) to petroleum derived diesel fuel, but manufactured from vegetable or animal fats. The environmental benefits or penalties of using this fuel are under dispute.” (Wikipedia)

To make it you will need just 3 ingredients which can be easily found at the grocery store:

• Vegetable oil
• Methanol
• Sodium hidroxyde

Some people built devices to make biodiesel and use in their cars but don’t know how safe it is for the car and how much power does it provide.
