A method of increasing the static coefficient of friction of an oleaginous composition, such as an ATF, comprising adding to a major portion of an oil of lubricating viscosity a friction increasing amount of an oil soluble friction increasing reaction product comprising (a) an oil soluble substituted or unsubstituted, saturated or unsaturated, branched hydrocarbyl group containing from about 12 to about 50 total carbon atoms, (b) a linking group, and (c) a nitrogen-containing polar group, wherein the polar group contains at least one nitrogen atom and, optionally, contains at least one atom selected from the group consisting of boron, oxygen and sulfur atoms, and wherein the polar group is linked to the branched hydrocarbyl group through the linking group.

Method for increasing the static coefficient of friction in oleaginous

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

This invention provides an oil-soluble complex of an oil-insoluble phosphorus-containing acid and an alcohol. This complex is a useful antiwear additive in lubricating oils, particularly automatic transmission fluids.

Oil soluble complexes of phosphorus-containing acids useful as

A method of controlling the friction coefficients and improving the friction durability of an oleaginous compositions, such as an ATF, comprising adding to the composition a combination of competing additives comprising (1) at least one friction modifying chemical additive having a polar head group and a friction reducing substituent group and (2) at least one non-friction reducing additive and/or friction increasing additive having the same polar group as the friction modifying chemical additive, but having a substituent group which has no material friction raising or lowering effect (non-friction reducing additive) or a substituent group which increases the friction coefficients (friction increasing additive) of the composition.

Increasing the friction durability of power transmission fluids through

A method of controlling the friction coefficients and improving the friction durability of an oleaginous compositions, such as an ATF, comprising adding to the composition a combination of competing additives comprising (a) at least one friction reducing chemical additive having a polar head group other than a dialkoxylated amino group and a friction reducing substituent group, and at least one non-friction reducing additive (b) having a dialkoxylated amino polar head group and having a substituent group which has no material friction raising or lowering effect (non-friction reducing additive) on the composition.

Friction modifier additives useful in power transmission compositions, particularly automatic transmission fluids, is disclosed. The additive comprises Component-1 alone formed by condensing a polyamine, such as tetraethylene pentamine, with an aliphatic mono acid, such as isostearic acid, or a mixture, and/or salt, of Component-1 and a Component-2 wherein Component-2 is an acid ester formed by reacting a heterodialkanol such as thiobisethanol and a hydrocarbyl substituted dicarboxylic acid or anhydride, such as octadecenyl succinic anhydride.

Amide containing friction modifier for use in power transmission fluids

This invention provides a novel antiwear and antioxidant additive for use in lubricating oils, particularly automatic transmission fluids. The novel additive is the reaction product of a phosphating agent and a thioalcohol. The reaction product is nonaggressive to silicone-based seals.

Non silicone aggresive alkyl phosphates as lubrication oil additives

A two-cycle oil additive composition and concentrate having improved detergency, lubricity and antiwear properties which more effectively controls deposits related to ring sticking comprising A) at least one dispersant prepared by reacting a carboxylic acid acylating agent with a polyalkylene polyamine and optionally a high molecular weight acylating agent; B) a second dispersant which is a succinimide such as prepared by acylating a polyalkylene polyamine with polyisobutylene succinic anhydride; and C) at least one polyolefin; at least one of the dispersants being a borated dispersant and which further optionally comprise at least one of the following: D) a sulfurized alkylphenol; and E) a phosphorous-containing antiwear agent.

A phosphorous- and sulfur-containing additive and its use to impart anti-wear properties to oleaginous compositions such as fuels and lubricating oils, particularly power transmission compositions, such as automatic transmission fluids, is disclosed. The additive comprises a mixture of products formed, for example, by simultaneously reacting (1) a beta-hydroxy thioether, such as thiobisethanol, (2) a phosphorous-containing reactant, such as triethyl phosphite and (3) optionally, a nucleophilic reactant capable of reacting with the episulfonium cation ##STR1## to form thioether species.
