Well my friend Leigh
sent me a link AGES ago which I never read because it said "Biodiesel". Biodiesel is no worries. Ha! I don't need to read about biodiesel any more! Biodiesel you simply put in your regular Diesel engine, no conversions necessary. The only thing you may need if you use biodiesel is to check your fuel filter. Biodiesel cleans out your fuel lines and deposits years of gunk in your filter.
ANYWAY. I just opened the email then, and it is great. It is a link to frybird
which is a US company which pre-makes all the bits to convert your car to oil. My next step will be to thouroughly read this site! It is recommended also by Kevin Kelly
