Combining a metal based friction modifier, such as a molybdenum dialkyldithiocarbamate, and certain esters of hydroxy carboxylic acids, such as short chain alkyl esters of citric or tartaric acid, e.g., tributyl citrate, has a synergistic effect on lowering the friction coefficient of lubricating oils allowing one to reduce the amount of metal based friction modifier needed to adequately formulate a lubricant with low friction characteristics.

Friction modifier composition for lubricants

A friction modifier composition for reducing friction in a lubricant comprising a fatty acid sorbitan ester that is solid or semi-solid. The fatty acid sorbitan ester is capable of being released into a lubricant at a rate of less than or equal to 0.15 grams per minute.

Fatty sorbitan ester based friction modifiers

Overbased MgO dispersions with high magnesium content and acceptably low viscosities are reproducibly prepared without gel formation by heating to 280-360&#xb0; C. a mixture of MgO, selected dispersants, low MW carboxylic acids, water and a combination of high boiling hydrocarbon and organic diluent, wherein water is more than 8%, typically more than 10% of the reaction mixture. No additional solubilizing or dispersing agents, promoters or reactants such as carbon dioxide, amines, alcohols etc are needed to obtain the desired dispersions. Compositions such as lubricating oils and fuels containing the overbased magnesium dispersions as additives are also disclosed.
