Methods of reducing stochastic pre-ignition events and/or carbonaceous deposits in a gasoline-fueled engine by adding at least 10 ppm by weight of a compound having at least one alkyl succinic acid group to a gasoline fuel, wherein said compound is the product of (a) and (b), wherein: (a) is an amine with at least one tertiary nitrogen, water, or a hydrocarbyl substituted alcohol; and (b) is a hydrocarbyl-substituted succinic acid and/or anhydride.

Fuel additive compositions for gasoline direct injection engines

A cleaning composition, which is suitable for cleaning fuel delivery systems, air-intake systems, intake valves, and combustion chambers, includes at least 3 wt. % of a polyether component, at least 5 wt. % of a polar solvent, and at least 5 wt. % a non-polar solvent. The polyether component is selected from polyethers, polyetheramines, and mixtures thereof.
