Compositions useful to improve power transmission in automatic transmission fluids, hydraulic fluids and the like as replacements for basic barium salts of sperm oil are obtained by reacting an excess of a barium base with the combination of a phenol (preferably an alkylphenol), a fatty acid and an alcohol, wherein the fatty acid and alcohol together contain at least 26 carbon atoms in straight-chain configuration. The compositions are preferably further reacted with carbon dioxide, and they may additionally be reacted with about 1-5% of anthranilic acid. |
