Drill yur own oil well and refine it yourself.
All it takes is a little still work.
Oh how I wish.
It would be nearly impossible for an individual to drill, dewater and separate, ththen refine,hydrocrack,desulfur,remove the benzene and other cyclohydrocarbons that are all carcinogens and illegal in gasoline now. Then distill the cleaned fuel into at least 87 RON/M2.
You can however turn virtually anything sweet or starchy into 190 proof hydrous ethanol and run a properly tuned engine on it. All you need is a column still and some sour mash starter cultures. Henry Ford designed his first cars including the Model T to run on hydrous ethanol because at the time gasoline was a specialty product considered waste by standard oil who dumped it literally into the ditch. Only once standard oil realised it could be used in the Model T and Model A and Fordson tractors did they then set out on a campaign to crush small distilleries making ethanol. Guess who was a key player in prohibition you standard oil funded it BIG TIME. Prior to prohibition farmers distilled ethanol for lighting,cooking, fuels for tractors which were high technology at the time. The Fordson being a breakthrough just like the Model T and both could run on ethanol,kerosene made from coal not oil at the time or naptha solvent which is what gasoline eventually became. Spend some time reading about Henry Ford and his genius. He also proved that even in his day a single acre of potatoes could make enough alcohol to plow 100 additional acres of crops and harvest them too. Using of course his Fordson tractor machines. He had no idea that cellulose ethanol would become possible which quadruples the yields of ethanol per acre using the stalks and leaves and roots of a plant in addition to the starches. He would be flabbergasted by the numbers possible today.
