gasoline n.
"light, volatile liquid obtained from distillation of petroleum," 1864, a variant of gasolene (from 1863 in Britain), which apparently was a trade name at first, from gas (n.1) in its then-popular loose sense of "compound of gases used for illuminating and heating purposes;" the -ol probably here represents Latin oleum "oil" and the ending is from the chemical suffix -ine (2). Shortened form gas was in common use in U.S. by 1897. Gas station as a fuel filling station for automobiles recorded by 1924.
