A transmission fluid composition contains a major amount of a lubricating oil basestock, and a minor amount of an additive package comprising: (i) a mixture comprising two or more phosphites and/or phosphates; (ii) one or more thioester compounds; (iii) one or more zinc dihydrocarbyl dithiophosphate compounds; and (iv) one or more oil-soluble or dispersible molybdenum-containing compounds. Such a transmission fluid may be used for controlling and/or reducing wear, e.g., in a manual transmission.

Transmission fluid composition for improved wear protection

Sulfurized calcium phenate detergents having a reduced unsulfurized alkyl-substituted phenol content are made by:

Metal detergents

A sulphurised calcium phenate detergent is made by (i) reacting hydrogenated distlled CNSL with a calcium salt and sulphur in the presence of a promoter and process solvent; (ii) reacting the product of (i) with additional calcium salt and promoter, and with a co-surfactant, and then carbonating; and optionally (iii) further carbonating the reaction mixture to obtain overbased sulphurised calcium phenate.
