Reformulated Blendstock for Oxygenate Blending (RBOB) gasoline is a fuel product made from refined crude oil. RBOB gasoline often goes by the names gasoline, petro gasoline or petrol. Edwin Drake, the first American to drill for oil, discovered gasoline by accident when he was distilling oil to make kerosene for heating. Drake considered gasoline a useless byproduct of the distillation process and discarded it. However, after the invention of the automobile in 1892, gasoline became the main source of fuel for cars and light-duty vehicles. This makes gasoline one of the most important and well-known commodities in the world.
