The present invention is directed to a method for improving one or more of the control of deposit formation and friction in an engine lubricated using a lubricating oil comprising a base oil and additives by employing as the additive the necessary combination of a borated hydroxyl saturated hydrocarbyl ester amide-amine mixture, zinc dialkyl dithiophosphate, and metal salicylate detergent, the deposit formation and friction being improved as compared to a lubricating oil containing the borated hydroxyl saturated hydrocarbyl ester amide-amine mixture, zinc dialkyl dithiophosphate and a detergent other than metal salicylate, such as metal phosphate and/or metal sulfonate.

Method for reducing one or more of deposits and friction of a lubricating oil

The air release rate of lubricating compositions is significantly enhanced when the composition is formulated with one or more vinyl aromatic-olefin block copolymers that forms a micelle-like structure in the oil. Compositions having the specified copolymers retain less than about 2.5% air after 1 min. at 50&#xb0; C. when tested by ASTM D 3427.

Lubricant air release rates

A continuous process for the manufacture of alkylated diphenyl compounds such as diphenyl ether and diphenyl sulfides by alkylating a diphenyl compound such as diphenyl ether with an olefinic alkylating agent by passing a continuous flow of the diphenyl compound and the olefin over a solid particulate catalyst which comprises a molecular sieve of the MCM-22 family. The process is flexible. By adjusting feed compositions, products of different compositions and wide range of properties are produced.

Preparation of alkylated diphenyl oxides

Lubricant or fuel compositions comprising 1) an organo, ring-substituted diphenyl sulfide, e.g. a monoalkyldiphenyl sulfide; 2) a dispersant component comprising at least one polymer-substituted succinimide, succinamide and/or succinic acid ester in which the alcohol or phenol moiety of the ester group may optionally contain amide, imide or amine nitrogen functionality, or mixtures of said amide, imide and/or ester; and 3) a dithiophosphate, e.g., a zinc dithiophosphate. The compositions have superior antiwear and extreme pressure properties.

Lubricant and fuel compositions containing an organo-substituted

Polymeric amine sulfur-containing heterocyclic reaction products have been found to be effective antiwear and corrosion inhibiting additives for fuels, including gasolines, and lubricants with excellent high temperature decomposing, cleanliness and detergency/dispersancy features.

Polymeric amine-heterocyclic reaction products as fuel and lubricant

Phenolic imidazolines prepared via one-step condensation of hydrocarbylpolyamino-phenols and carbonyl generating species have been found to be effective antioxidants in lubricant applications. These additives are derived from a one-step reaction using low cost phenolic amines and carbonyl compounds. In addition to their antioxidant activity, they are, because of the presence of the cyclic imidazoline groups, also expected to exhibit corrosion inhibiting and metal passivating activity.

Phenolic imidazoline antioxidants

Oxygenated alkyl amines synthesized using carbonyl coupling reactions have combustion chamber deposit reducing properties and oxidative stability characteristics beneficial for dispersant/detergent applications in fuels and lubricants.

Fuel composition with reaction product of oxygenated amine, dicarbonyl

Grease compositions, wherein the grease is thickened with a metal hydroxy-containing soap grease thickener are provided. Other essential ingredients of the compositions include borated hydroxyhydrocarbyl esters and phosphorus and/or sulfur compounds.

Grease composition

Triaole-dialkyl maleate derivatives have been found to be effective metal passivators and antiwear additives for lubricants and fuels.

Triazole-maleate adducts as metal passivators and antiwear additives

A lubricant additive having antiwear and antioxidant properties is the reaction product of a sulfur-containing carboxylic acid and an etheramine, preferably 3,3'-thiodipropionic acid and N-isoeicosyloxypropyl-1,3-diaminopropane which is post reacted with an aliphatic alcohol, preferably oleyl alcohol, an aliphatic amine, preferably a tert-C.sub.12 to C.sub.14 amine and/or a trialkyl phosphite, preferably a tributylphosphite. The post-reaction product contains at least one ester, amide and/or phosphonate functional group.

Antiwear and antioxidant additives

Polyalkylene amine coupled carboxylates are effective multifunctional additives, providing cleanliness to fuels and lubricants as well as friction-reducing and corrosion-inhibiting properties.

Additives for fuels and lubricants

Polyalkylene amine coupled heterocyclic compounds are effective multifunctional additives, providing cleanliness to fuels and lubricants as well as anti-wear, friction-modifying, thermal and oxidative stabilizing properties. The beneficial effects of the product of the instant invention apparently result from an internal synergism between the polyalkylene amine groups and the heterocyclic groups.

The invention relates to lubricant and fuel additives having antiwear and friction reducing properties. The invention also relates to compositions of oils with viscosities appropriate for lubricants, greases produced therefrom, and fuels and methods for making these compositions. Described in this invention are products of nitrogen heterocycles, such as benzotriazole and tolyltriazole, with amines, such as alkyl amines, aliphatic diamines, alicyclic amines, heterocyclic amines, propylene amines, and aliphatic etheramines, that are linked using carbonyl compounds (e.g., aldehyde, ketone or glyoxal). Additionally, products generated by the reaction of carboxylic acids or carboxylic acid generating compounds (e.g., salts or esters) with carbonyl (e.g., aldehyde, ketone or glyoxal) coupled nitrogen heterocycles and amines, including those described above, are also included in this invention. These products can be used in fuels and lubricants to produce improved antiwear and friction reducing properties.

Friction modifiers and antiwear additives for fuels and lubricants

Tolyltriazole derived esters of tri, tetra, and poly carboxylic acids or an acid generating compound have been found to be effective lubricity additives for lube oils, greases, or distillate fuels.

Lubricant compositions comprising tolyltriazole-derived tri/tetra esters
