| description | The invention provides an unleaded gasoline composition comprising a major amount of hydrocarbons boiling in the range from 30° C. to 230° C. and 2% to 20% by volume, based on the gasoline composition, of diisobutylene, the gasoline composition having Research Octane Number (RON) in the range 91 to 101, Motor Octane Number (MON) in the range 81.3 to 93, and relationship between RON and MON such that(a) when 101>=RON>98, (57.65+0.35 RON)>=MON>(3.2 RON-230.2), and(b) when 98>=RON>=91, (57.65+0.35 RON)>=MON>=(0.3 RON+54),with the proviso that the gasoline composition does not contain a MON-boosting aromatic amine optionally substituted by one or more halogen atoms and/or C1-10 hydrocarbyl groups; a process for the preparation of such a gasoline composition; and a method of operating an automobile powered by a spark-ignition engine equipped with a knock sensor, with improved power output. |
