Problems solved by technology

[0019] For example, molybdenum friction modifiers generally outperform ashless friction modifiers in the marginal region, and achieving similar levels of friction improvement with ashless friction modifiers alone remains a challenge

[0104] formula

[0105] Tables 1 and 2 give the formulations tested.

[0106] The formulations in Tables 1 and 2 included conventional detergents, dispersants, pour point depressants, antioxidants, viscosity modifiers, and zinc dithiophosphate additives as additive packages in the diluent oil.

[0107] The base oils used in the formulation were polyalphaolefin base oils (PAO-4 from BP Amoco under the trade designation "DURASYN 164" and PAO-5 from Chevron Oronite under the trade designation "SYNFLUID 5") and The name "PRIOLUBE 1976" is a blend of ester based oils from Uniqema.

[0108] Glyceryl monoolein used was the material available from Oleon Chemicals under the trade designation "RADIASURF 7149".

[0109] The commercially available coconut fatty acid nitrile mixture (mainly C12 nitrile) used was the material obtained from Akzo Nobel under the trade designation "ARNEEL 12".

Abstract

A lubricating oil composition comprising base oil, glycerol monooleate and one or more nitrile compounds; and a method of lubricating an internal combustion engine comprising applying said lubricating oil composition thereto.

Description

technical field [0001] The present invention relates to a lubricating oil composition, in particular a lubricating oil composition suitable for lubricating internal combustion engines and having improved friction reduction and fuel economy. Background technique [0002] Increasingly stringent automotive regulations on emissions and fuel efficiency place increasing demands on engine manufacturers and lubricant formulators to come up with effective solutions to improve fuel economy. [0003] Optimizing lubricants with high-performance base stocks and novel additives represents a flexible solution to this growing challenge. [0004] Friction reducing additives (which are also referred to as friction modifiers) are important lubricant components for reducing fuel consumption, and a variety of such additives are known in the art. [0005] Friction modifiers can be conveniently divided into two classes, metal-containing friction modifiers and ashless (organic) friction modifiers....
