  • Friction modifier for poor lubricity fuels
    Patent number: 6589302
    Abstract: 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.
