Abstract

The invention discloses a lubricant composition which, unlike a conventional lubricant composition, has excellent effects of preventing abrasion and reducing friction. The lubricant composition of the invention comprises a base oil and a specific organometallic compound dissolved in the base oil. The organometallic compound can be completely dissolved in the base oil and has a storage stability of at least 6 months or more. Therefore, the lubricant composition is free from the limitation of the use amount due to the solubility. As the specific organometallic compound is contained, the lubricant composition has the effect of gaining a tremendous increase in the bearing wear resistance performance for engine protection as compared with a conventional lubricant, the engine cleanability is improved, the friction performance is also improved, and thus the effect of improving the fuel efficiency can be expected.

Description

technical field [0001] The present invention relates to a lubricant composition, in particular to a lubricant composition comprising a base oil and a specific organometallic compound dissolved in the base oil so as to be suitable for engine protection performance Gasoline engine (gasoline engine) oil or diesel engine (diesel engine) oil with excellent engine wear performance. Background technique [0002] Lubricants are used in automotive engines, transmissions, bearings, gears, industrial gears, and other machinery to reduce friction and wear and improve fuel efficiency. Such lubricants generally include dispersants, cleaning agents, anti-wear agents, antioxidants, anti-corrosion agents, etc., and include various components that are not limited thereto. [0003] Such lubricants or lubricating oils serve to improve the operation of moving bodies by reducing friction and increasing efficiency between moving bodies while conserving required energy. [0004] Recently, attempt...
