The present invention generally relates to lubricating oil compositions useful for automatic transmissions, and particularly transmission oils for automotive automatic transmissions in battery electrical vehicles (BEVs), hybrid vehicles (HVs) and plug-in hybrid vehicles (PHVs). The lubricant is free of metal compounds (e.g., Ca, Mo, or Zn) and demonstrates high volume resistivity, wear protection, and copper corrosion resistance.

Lubricating oil compositions for automatic transmissions

The present invention generally relates to lubricating oil compositions useful for automatic transmissions, and particularly transmission oils for automotive automatic transmissions and/or continuously variable transmissions using wet clutch systems, in particular wet paper clutch containing a small amount of cellulose fiber and/or aramid fiber.

Lubricating oils for automatic transmissions

A fuel additive composition containing an alkylene-oxide-adducted hydrocarbyl amide and a friction modifier is disclosed. The alkylene-oxide-adducted hydrocarbyl amide and friction modifier are surprisingly useful for improving the acceleration response and the driving performance of vehicles having internal combustion engines when used as fuel additives in hydrocarbon-based fuels, such as gasoline fuel or diesel fuel.

Fuel additive composition and fuel composition containing the same

A fuel additive composition containing at least one amide compound selected from the group consisting of a fatty acid alkanol amide and a hydrocarbyl amide, a polyalkylene-oxide, and a friction modifier. The fuel additive composition is surprisingly useful for improving the acceleration response and the driving performance of vehicles having internal combustion engines when used as fuel additives in hydrocarbon-based fuels, such as gasoline fuel or diesel fuel.

A biodegradable multipurpose functional fluid for agricultural or construction machinery, comprising a base oil, a detergent-dispersant and an antioxidant (and a viscosity index improver if desired), in which the base oil is a fatty acid triester of trimethylolpropane obtained from a fatty acid that either has from 40% to 70% by weight of caprylic acid and from 20% to 50% by weight of capric acid, or is derived from a coconut oil which has been adjusted to have a stearic acid content of from 10% to 20% by weight.
