Definitions
- This invention relates to engine oil compositions, and more particularly to engine oil compositions which provide excellent fuel efficiency and viscosity at low temperatures and are less in evaporation loss.
- Japanese Patent Laid-Open Publication No. 8-302378 discloses an engine oil composition which comprises a specific base oil, an alkaline earth metal salicylate-based detergent, zinc dialkyldithiophosphate, a polybutenylsuccinimide-based ashless dispersant, a phenol-based ashless oxidation inhibitor, a molybdenumdithiocarbamate-based friction modifier, a viscosity index improves, in a specific amount, respectively.
- An object of the present invention is to provide an engine oil composition which is reduced more in viscosity than conventional fuel efficient engine oils and provide excellent fuel efficiency and viscosity characteristics at low temperatures with less evaporation loss by blending suitable additives.
- an engine oil composition which comprises (A) a lubricant base oil having a kinematic viscosity at 100° C. of 2 to 6 mm 2 /S, a viscosity index of 120 or more and a total aromatic content of 15 percent by mass or less and (B) a polymethacrylate-based viscosity index improver blended in such an amount that the composition has a kinematic viscosity at 100° C. of 4.0 to 9.3 mm 2 /s.
- an engine oil composition which comprises (A) a lubricant base oil having a kinematic viscosity at 100° C. of 2 to 6 mm 2 /S, a viscosity index of 120 or more and a total aromatics content of 15 percent by mass or less; (B) a polymethacrylate-based viscosity index improver blended in such an amount that the composition has a kinematic viscosity at 100° C. of 4.0 to 9.3 mm 2 /s; and (C) molybdenumdithiocarbamate.
- the polymethacrylate-based viscosity index improver have preferably have an weight-average molecular weight of 180,000 or more.
- a lubricating base oil referred to as Component (A) in an engine oil composition according to the present invention has a kinematic viscosity at 100° C. of which upper limit is 6 mm 2 /s, preferably 5 mm 2 /s and lower limit is 2 mm 2 /s, preferably 3 mm 2 /s.
- Lubricant base oils in excess of the upper limit would lead to increased fluid resistance resulting in increased loss caused by wear occurring at engine parts to be lubricated, while those of less than the lower limit would lead to insufficient oil-film formation, resulting in less lubricity and increased evaporation loss.
- Component (A) has necessarily a viscosity index of 120 or more. Such a viscosity index value is contributive to the production of an engine oil composition having excellent low-temperature viscosity characteristics. Base oils having a viscosity index of less than 120 would lead to a necessity to bring it down lower viscosity, resulting in the increased evaporation loss and viscosity of the resulting engine oil.
- the upper limit of aromatic content of Component (A) is 15 percent by mass, preferably 10 percent by mass, and most preferably 5 percent by mass. Base oils in excess of the upper limit would fail to achieve synergistic effects with each additive to be used in the present invention. No particular limitation is imposed on the lower limit of aromatic content. However, Component (A) has preferably a total aromatic content of 2 percent by mass or more because that having a total aromatic content of less than 2 percent by mass would not possibly exhibit solubility to various additives.
- total aromatic content denotes an aromatic fraction content measured in accordance with ASTM D2549. Incorporated by the aromatic fraction are generally alkylbenzenes, alkylnaphthalenes, anthracene, phenanthrene, alkylated products thereof, compounds in which 4 or more benzene rings are condensed, and compounds having hetero-aromatics, such as pyridines, quinolines, phenols, and naphthols.
- Eligible base oils for the present invention are mineral lubricating oils, synthetic lubricating oils, and mixtures of two or more of these oils mixed in a suitable ratio.
- the base oils are exemplified by mineral lubricating oils, mixtures of mineral lubricating oils and non-aromatic containing synthetic lubricating oils, and mixtures of aromatic-containing synthetic lubricating oils and non-aromatics containing synthetic lubricating oils.
- mineral lubricating oil used herein denotes not only a single mineral lubricating oil but also a mixture of two or more mineral lubricating oils. Therefore, when using two more mineral lubricating oils as the base oil, there may be used not only a mixture of mineral lubricating oils each having a total aromatic content of 15 percent by mass or less but also a mixture of a mineral lubricating oil having a total aromatic content of 15 percent by mass and a mineral lubricating oil having a total aromatic content exceeding 15 percent by mass as long as the resulting base oil has a total aromatic content of 15 percent by mass or less.
- mineral lubricating oil examples are those obtained by subjecting a lubricant fraction obtained by vacuum-distilling an atmospheric residue derived from the atmospheric distillation of crude oil to one or more refining processes such as solvent deasphalting, solvent extraction, hydrocracking, solvent dewaxing, and hydrorefining.
- aromatic-containing synthetic lubricating oil examples include alkylnaphthalenes and alkylbenzenes.
- non-aromatic containing synthetic lubricating oil examples include polybutens and hydrides thereof; poly- ⁇ -olefins such as 1-octene oligomer and 1-decene oligomer, and hydrides thereof; diesters such as ditridecylglutarate, di-2-ethylhexyladipate, disodecyladipate, and di-2-ethylhexylcebacate; polyolesters such as trimethylolpropanecaprylate, trimethylolpropanepelargonate, pentaerythritol-2-ehylhexyanoate, and pentaerythritolpelargonate; and mixtures thereof.
- Each of these lubricating oil exhibits its peculiar viscosity-temperature characteristics, i.e., viscosity index.
- a lubricating oil used as a base oil of the present invention has a viscosity index of 120 or more, even though a lubricating base selected from the above has a viscosity index of less than 120, it may be used in combination with those having a viscosity index of 120 or more.
- Component (B) of an engine oil composition according to the present invention is a polymethacrylate-based viscosity index improver blended in such an amount that the resulting composition has a kinematic viscosity at 100° C. of 4.0 to 9.3 mm 2 /s.
- the kinematic viscosity at 100° C. of the resulting composition in excess of 9.3 mm 2 /S would not provide sufficient fuel efficiency, while that of less than 4.0 mm 2 /s would improve fuel efficiency caused by the reduced viscosity of the composition and viscosity at low temperatures but fail to have sufficient lubricity as an engine oil.
