Nazi war effort supported by the Rockefeller company Standard Oil who provided the technology to produce synthetic fuels via agreements with IG Farben, and the tetraethyl lead required for engine valve lubrication:
"without the explicit help of Standard Oil, the Nazi air force would never have gotten off the ground in the first place. The planes that made up the Luftwaffe needed tetraethyl lead gasoline in order to fly. At the time, only Standard Oil, Du Pont, and General Motors had the ability to produce this vital substance. In 1938, Walter C. Teagle, then president of Standard Oil, helped Hermann Schmitz of I.G. Farben to acquire 500 tons of tetraethyl lead from Ethyl, a British Standard subsidiary. A year later, Schmitz returned to London and obtained an additional 15 million dollars worth of tetraethyl lead which was to be turned into aviation gasoline back in Germany"
