The present invention relates to a fuel composition, in particular for an internal combustion engine, comprising: (1) at least one liquid hydrocarbon cut from one or more sources selected from the group consisting of mineral, animal, plant and synthetic sources, and (2) from 1 to 10,000 ppm by weight of an additive which comprises at least 6% by weight of free sterols and/or sterol esters and from 70% to 94% by weight of free fatty acids, these contents being expressed in relation to the total weight of the additive. The present invention also relates to the use of such an additive for improving the lubricity properties of an engine fuel.

A composition is provided for a non-aqueous foaming aerosol cleaner or lubricant. Foam builders, especially silicone glycol copolymers, are used to generate high density foam of the solvent-based formula. A cleaning product variant may be introduced via an air intake route for loosening deposits in an internal combustion engine. The high foam aerosol product dispenses easily without causing engine stalling. A process of lubricating a target substrate is also provided.
