I remember the tales from back in the 70s fuel crisis years about China sneaking barges, tankers of gasoline into the US because they had such a surplus of raw gasoline, no additives, etc caused by their demand for diesel and no use for gasoline itself.
To make diesel fuel you have to refine gasoline out first whether you want it or not.
Back in the beginning, gasoline was the first dry-cleaning fluid since they were trying to find uses for it here.
Yes, but the process is simpler. You can skip the thermal-cracking process that is used to convert diesel grade petroleum feedstock into gasoline feedstock.
