摘要:
A lubricating composition comprising an oil of lubricating viscosity, 1 to 1000 parts per million by weight of titanium in the form of an oil-soluble titanium-containing material, and at least one additional lubricant additive provides beneficial effects on properties such as deposit control, oxidation, and filterability in engine oils.
摘要:
Organo-Cobalt complexes having long chain saturated and unsaturated alkyl functionality as multifunctional additives in crankcase oils and the method of preparation thereof.
摘要:
A lubricant and concentrate composition comprises a hindered-phenol-containing diester antioxidant derived from a hydrocarbyl diol or an amide diol. A method for improving the performance of a lubricant composition, especially a lubricant composition for an internal combustion engine, comprises the antioxidant.
摘要:
A low-sulfur, low-phosphorus composition comprising an oil of lubricating viscosity; a substantially nitrogen-free sufurized olefin antiwear agent; a nitrogen-containing dispersant; and an overbased detergent selected from the group consisting of salixarates, saligenins, salicylates, and glyoxylates; containing less than about 0.1 percent by weight phosphorus, less than about 0.5 percent by weight sulfur, and having less than about 1.2% sulfated ash, is useful for lubricating a diesel engine, exhibiting good antiwear performance.
摘要:
Formulations using tartaric compounds of the present invention in a low sulfur, low ash and low phosphorous lubricant lower wear, and friction and improves fuel economy.
