Fuel additive for spark-ignition engines, useful for increasing motor octane number, comprises high molecular weight polyalkene and detergent additive

摘要

Fuel additive for spark-ignition engines comprises a high molecular weight polyalkene, a detergent additive and optionally other additives in a solvent. An Independent claim is also included for a fuel composition for spark-ignition engines, comprising a major amount of a hydrocarbon fuel and a motor octane number (MON)-increasing amount of a high molecular weight polyalkene.
