A fuel composition comprising (a) a major amount of an internal combustion engine hydrocarbon fuel containing at least one alcohol, it being provided that MTBE is substantially absent from the fuel and (b) a friction modifying amount of a reaction product of at least one natural or synthetic oil and at least one alkanolamine is provided. Also provided is a method for operating an engine employing the fuel composition therefor.

Fuel composition containing friction modifier

A fuel additive composition for improving the delivery of friction modifier to the lubricant oil of an internal combustion engine comprising (a) a friction modifying amount of a reaction product of at least one natural or synthetic oil and at least one alkanolamine; and, (b) at least one fuel detergent is provided. Also provided is a fuel composition containing the fuel additive composition and a method for operating an engine employing the fuel composition therefor.

Fuel additive composition for improving delivery of friction modifier

An additive concentrate for improving the lubricity of low sulfur fuels comprises an additive composition diluted in an aromatic solvent, said composition comprising the reaction product of a first glyceride possessing an unsaturated fatty acid content of at least about 40 mole %, based on the total weight of fatty acid present in the first glyceride, and an iodine number of greater than 35, a second glyceride possessing an unsaturated fatty acid content of less than about 20 mole %, based on the total weight of the fatty acids present in the second glyceride, and an iodine number of less than 35, and, at least one alkanolamine. The concentrate remains fluid and stable at low temperatures and, when added to low sulfur fuels, improves lubricity, enhances fuel economy and minimizes engine deposits.

Two-cycle engine fuel composition and method for using same

A method of impeding the evaporation of a solvent by at least partially dissolving a solvent soluble polymer in the solvent in sufficient amounts so as to impede the evaporation of the solvent is disclosed. In one embodiment the soluble polymer may be selected from the group including oligomeric or polymeric homo-, co-, and terpolymers wherein a vinylcyclohexyl moiety comprises at least 10% weight of the polymer. Another aspect is generally directed to a method of storing a solvent including placing the solvent in a suitable container for storage, and dissolving in at least a portion of the solvent sufficient amounts of a soluble polymer so as to impede the evaporation of the solvent. Also described are compositions including a solvent and a polymer dissolved in the solvent so as to impede evaporation of the solvent.
