Definitions
- Lubricating oils containing molybdenum compounds like molybdenum dithiocarbamates have been known in the literature.
- Le Suer in US Patent 3,541 ,014 showed the value of using oil soluble molybdenum compounds in lubricants in combination with other additives to improve extreme pressure capabilities and an ti wear properties of the lubricants.
- Papay et al. in US Patent 4,178,258 discloses a lubricating oil composition suitable for use in an internal combustion engine, comprising a major amount of a mineral oil and a minor wear and friction reducing amount of an oil soluble molybdenum dithiocarbamate (MoDTC). Inoue et al.
- the present invention provides a composition suitable for qualifying as an ILSAC GF-3 engine lubricating oil comprising the following components: a major amount of a mineral oil classified as an API Group I base stock, wherein said base stock contains 300 ppm or more of sulfur by weight, a molybdenum dithiocarbamate in an amount to deliver 25-600 ppm of molybdenum to the finished engine oil, a succinimide dispersant having a polyolefin backbone, where the polyolefin has a number average molecular weight of at least 1300, a zinc dialkyldithiophosphate derived from at least one secondary alcohol, and at least one oxidation inhibitor selected from the group consisting of hindered phenols, alkylated aromatic amines, and sulfurized olefins.
- the present invention further provides a method for inhibiting oxidation in an ASTM Sequence IIIF test when using high sulfur API Group I base stocks, comprising the following steps: treating a high sulfur Group I base stock with an additive package which is capable a passing a Sequence IIIF test when formulated in Group II base stocks; and adding to said base stock a MoDTC in an amount suitable to deliver 25-600 ppm of molybdenum to the finished lubricating oil.
- the additive package capable of passing the Sequence IIIF test typically comprises a succinimide dispersant having a polyolefin backbone, where the polyolefin has a number average molecular weight of at least 1300; a zinc dialkyldithiophosphate derived from at least one secondary alcohol; and at least one oxidation inhibitor selected from the group consisting of hindered phenols, alkylated aromatic amines, and sulfurized olefins.
- Group I >0.03 and/or ⁇ 90 80 to 120
- Groups I, II, and III are mineral oil base stocks.
- Component (a) being high sulfur would be a Group I base oil.
- the high sulfur oils are a subset of the Group I base oils.
- the present invention is also useful in mixtures of various Groups of base oils, provided that the sulfur level in the total base stock mixture is at least 300 ppm.
- a major amount of a high sulfur Group I base stock could be mixed with smaller amounts of base stocks from one or more of Groups II, III, IV, or V.
- the amount of component (a) in the compositions of the present invention is generally 50% or greater.
- the amount of component (a) is 70 to 96%. More preferably the amount of component (a) is 85 to 95%.
- Component (b) is one or more molybdenum dithiocarbamates (MoDTC).
- MoDTCs include commercial materials such as VanlubeTM 822 and MolyvanTM A from R.T. Vanderbilt Co., Ltd., and Adeka Sakura-LubeTM S-100, S-165 and S-600 from Asahi Denka Kogyo K.K.
- Other molybdenum dithiocarbamates are described by Tomizawa in U.S. Patent 5,688,748; by Ward in U.S. Patent 4,846,983; by deVries et al. in U.S. Patent 4,265,773; and by Inoue et al. in U.S. Patent 4,529,536.
- a useful C-8 group is the 2-ethylhexyl group; thus, the di-2-ethylhexyl dithiocarbamate is a preferred group.
- the aminoalkyl groups which can serve as Ri or R 2 typically arise from the use of a polyalkylenepolyamine in the synthesis of the dithiocarbamate moiety.
- the number average molecular weight of the polyolefin from which dispersant is derived is preferably 1300 to 5000 and more preferably 1500 to 3000.
- the most preferred dispersant is derived from a polyolefin succinic acid or anhydride where the average number of succinic groups per polyolefin group is greater than 1.3, and more specifically 1.3 to 2.5.
- the polyolefin is polyisobutylene.
- Dispersants of this type are disclosed by Meinhardt et al. in US Patent 4,234,435. They are further described in engine oil formulations by Ripple et. al in US Patents 4,904,401 and 4,981,602, and their use in combination with component (d) is disclosed.
