An oil-soluble reaction product of phosphorus-, low molecular weight basic nitrogen-, and optional boron-containing compounds is provided. This reaction product can solubilize significantly more phosphorus and boron per weight of compound than other known compounds and is used as an antiwear, antioxidant, and extreme pressure additive in lubrication oils.

Low molecular weight basic nitrogen-containing reaction products as

The anti-shudder durability of power transmitting fluids, particularly automatic transmission fluids, is improved by incorporating a combination of low potency friction modifiers and phosphorus-containing compounds. The anti-shudder durability of these fluids may be further enhanced by inclusion of a metallic detergent and/or a polyol ester friction modifier.

Power transmitting fluids with improved anti-shudder durability

An oil-soluble reaction product of at least one nitrogen-containing compound, at least one phosphorus-containing compound, and at least one mono- or di-sulfide-containing alkanol is provided, which improves friction and/or wear performance of a lubrication oil.
