This invention relates to a lubricating composition comprising or resulting from the admixing of: base oil, detergent, and one or more metal alkanoates having a quaternary carbon atom at the 2 position, the 2 position, or both the 2 and 2 positions, where the lubricating composition preferably has an adhesive wear of 100 hours or more, a foam volume of 70 ml or less at 24 C., and 50 ml or less at 93.5 C., and, optionally, a total base number of 7 mgKOH/g or more.

Lubricating oil compositions are disclosed that are suitable for use in all engine types and that provide a reduced Average Friction/Traction coefficient in use, with attendant improvement in fuel economy performance, especially retained fuel economy performance. The disclosed compositions are also advantageous in that molybdenum-based friction modifying ingredients previously considered crucial to reducing friction from metal-metal contact and high molecular weight PIBSA-PAM dispersants can be omitted or used at lower treat rates without impairing friction-reducing or fuel economy performance.

This invention relates to a diesel engine lubricating oil composition comprising or resulting from the admixing of: (i) base oil, (ii) a functionalized polymer, (iii) an overbased magnesium based detergent, (iv) an overbased calcium based detergent and (iv) one or more, optionally borated, higher and lower molecular weight PIBSA-PAM dispersants. The composition has a total sulfated ash of less than or equal to 1.0 wt. %, a kinematic viscosity at 100 C. of 5 to 20 cSt, a total phosphorous level of less than or equal to 0.120 wt. %, and a total sulfur level of less than or equal to 0.4 wt. % and provides a Cummins ISM oil filter delta pressure (OFDP) test result at 150 hours of less than 30 kPa. Also provided are a method of making the composition, a method of lubricating a diesel engine, a method of improving wear performance and soot dispersancy and reducing emissions of a diesel engine, and a diesel engine oil additive concentrate composition.

The present disclosure provides a drag reducing agent. In an embodiment, the drag reducing agent includes a polymer and a liquid carrier. The polymer is composed of one or more C.sub.6-C.sub.14 -olefin monomers. The polymer includes a residual amount of zirconium. The polymer has an absolute weight average molecular weight (Mw.sub.(Abs)) greater than 1,300,000 g/mol and a (Mw.sub.(Abs)/Mn.sub.(Abs) from 1.3 to 3.0.

A grease composition includes a thickener, a base oil, and an additive. The additive contains 0.1 to 10% by mass of a molybdenum-containing extreme-pressure agent, 0.1 to 10% by mass of Na sebacate, and 0.1 to 5% by mass of a sulfonate. A penetration of the grease composition is 235 to 370.

The present invention provides a magnetic viscous fluid comprising a magnetic particle, base oil, an inorganic cation exchanger with a siloxane bond, and silicone oil. A difference AB between a solubility parameter A of the base oil and a solubility parameter B of the silicone oil is 1.3 (cal/cm.sup.3).sup.1/2 or more.

The disclosed technology relates to compositions suitable for use as lubricants and lubricant additive compositions which comprise a 1,4-benzoxazine-derived antioxidant, wherein the antioxidant itself may also be described as a 1,4-benzoxazine compound, and optionally comprising other additives suitable for lubricants, such as an anti-wear agent, a detergent, or a dispersant.
