More Information
Summary:The invention provides a gasoline composition comprising a major amount of a gasoline suitable for use in a spark-ignition engine, which gasoline comprises a blend of at least two hydrocarbon refinery components boiling within the gasoline boiling range, at least one of which hydrocarbon refinery components has been treated with a fibrous clay mineral of the sepiolite, attapulgite and palygorskite groups, and a minor amount of a nitrogen-containing detergent containing a hydrocarbyl group having a number average molecular weight (Mn) in the range 750 to 6000; a process for the preparation of such compositions; and the use of such compositions in operation of a spark-ignition engine to give engine cleanliness benefits.
