In 1954, Mobil introduced a new and improved Mobilgas Special in response to trends toward new automobiles powered by high-compression engines that demanded higher and higher octane gasolines.
The newest formulas of Mobilgas Special was advertised as offering " A Tune-Up in Every Tankful " due to a combination of chemicals known as the " Mobil Power Compound " which was designed to increase power, check pre-ignition ping, correct spark plug misfiring, control stalling and combat gumming up of carburetors.
Later Mobil campaigns advertised Mobilgas as the " New Car Gasoline " following extensive testing during the annual Mobilgas Economy Run.
