Non-stalling gasoline fuel compositions

Claim 1

A GASOLINE FUEL COMPOSITION COMPRISING A MAJOR AMOUNT OF A HYDROCARBON MIXTURE THAT BOILS IN THE GASOLINE RANGE, THAT HAS A 50 PERCENT ASTM DISTILLATION POINT NOT GREATER THAN ABOUT 220*F. AND THAT NORMALLY TENDS TO PROMOTE STALLING OF INTERNAL COMBUSTION ENGINES, AND CONTAINING A COMBINATION OF (A) 0.001 TO ABOUT 0.1 PERCENT BY WEIGHT OF THE COMPOSITION OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF ALKALI METAL, ALKALINE EARTH METAL, AMMONIUM AND ETHYOL AMMONIUM SALTS OF DIALKYL SULFOSUCCINIC ACIDS, THE ALKYL GROUPS OF WHICH EACH CONTAIN 7 TO 9 CARBON ATOMS, AT LEAST 6 OF WHICH ARE IN A STRAIGHT CHAIN, NO GROUP ATTACHED TO THE ALPHA CARBON ATOM OF SAID ALKYL GROUPS CONTAINING MORE THAN 7 CARBON ATOMS AND (B) ABOUT 0.25 TO ABOUT 0.75 PERCENT BY VOLUME OF THE COMPOSITION OF A LIGHT LUBRICATING OIL HAVING A VISCOSITY AT 100*F. OF ABOUT 50 TO ABOUT 500 S.U.S., THE AMOUNT OF SAID COMBINATION BEING SUFFICIENT TO REDUCE THE ENGINE STALLING CHARACTERISTICS OF THE GASOLINE COMPOSITION.
