How to Make Biodiesel Fuel?

Biodiesel fuel can be made by using used vegetable or animal cooking oil. You add a mixture of methanol and battery acid to the oil. This must be mixed for 2 hours and then stand overnight. Mix together lye and methanol and let sit for 8 hours. You then add the lye/methanol mixture to the oil mixture. Subsequent steps involve heating the mixture and then a ‘washing’ procedure.
