Thanks for the correction...I found this very informative article:
http://www.nexusmagazine.com/ulp1.html
Sure it's from a "new age" magazine but they didn't make the information up,
it's from other sources. Very informative on the history of petrol. I know
for a fact the oil companys dont want to make clean fuel in the first place.
My grandfather used to run his car on homemade petrol during the war because
his friend was developing a way of refining it from gum leaves...he was
killed by a hit man, my grandfather was certain was sent by Shell.
