 Various Mobil products during the Socony-Vacuum and Socony-Mobil years included Metro, Mobilgas and Mobilgas Special gasolines; Mobilfuel Diesel, MobilHeat and Mobil-flame heating oil, Mobil Kerosine, Lubrite, Gargoyle, Mobiloil and Mobiloil Special motor oils; Mobilgrease, Mobillubrication, Mobil Upperlube, Mobil Freezone and Permazone antifreezes, Mobilfluid automatic transmission fluid, Mobil Premiere tires, Mobil Stop-Leak, and Mobil Lustrecloth, among many others.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 were 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.
