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) a detergent comprising calcium salicylate; and (iv) a poly(alkylene amine)-based ashless dispersant endcapped with metallocene-catalyzed PAO arms. Such a transmission fluid may be used for controlling/reducing wear in at least partially electrically-powered transmissions and/or for cooling/insulating electrical/electronic components of at least partially electrically-powered drivetrains.

A wet friction clutch&#x2014;lubricant system wherein a wet friction clutch having a cellulose&#x2014;based friction lining having a surface coating of silica based particles, or a device including such a clutch, is lubricated with a lubricant composition a major amount of oil of lubricating viscosity and minor effective amounts of performance enhancing additives including (a) ashless dispersant; (b) organic phosphorus compound and (c) borated detergents; and optionally, (d) an auxiliary friction modifier.

Wet friction clutch&#x2014;lubricant systems providing high dynamic coefficients of friction through the use of borated detergents

Lubricating oil compositions having excellent friction stability comprise a base lubricating oil, an oil soluble source of phosphorus and a defined polyalkylene polyamine-based friction modifier that has been reacted with a borating agent to convert at least one secondary amine group into the corresponding boric acid ester or boric acid salt.

Boron-containing lubricating oils having improved friction stability

A lubricating oil composition is disclosed comprising at least 10% by weight of the total oil composition of an ester of phthalic acid having a viscosity index less than 100. The lubricating oil composition has improved fuel economy and wear performance.
