http://www.etymonline.com/index.php?term=gasolinegasoline (n.) Look up gasoline at Dictionary.com
"lightest volatile liquid obtained from distillation of petroleum," 1864 (alternative spelling gasolene is from 1865), from gas (n.) + -ol (probably here representing Latin oleum "oil") + 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.
Gas-ol-ine.
Gas-oil-chemical.

P.S. To this day I don't understand "possum" vs "opossum".
