    摘要: An engine oil including a base oil in a range of about 70 to 85 wt %. The engine oil includes at least one additive in a range of about 15 to 30 wt %, such as, an antioxidant, a cleaning agent/detergent, a dispersing agent, a wear resistant agent, a viscosity index improving agent, a pour point depressant, a rust/corrosion inhibiting agent, a foam inhibiting agent, and an extreme pressure agent. The engine oil further includes an additive including an organometallic compound of a catalyst consisting of a catalytic element in a range of about 0.001 to 0.05 wt %.

    摘要: The present invention provides a lubricating oil composition, which is capable to maintain sufficient low-friction (i.e. fuel saving performance) even when the lubricating oil is contaminated with soot and metal abrasion powder, which is excellent in durability with regard to anti-wear property and detergency, as well as oxidation stability, and which is capable to lower the ash content and to sufficiently maintain the performance of exhaust-gas after-treatment device for a long term. The lubricating oil composition comprises a lubricant base oil containing a base oil (X) of which % CP is 70 or more, % CA is 1 or less, viscosity index is 115 or more, and CCS viscosity at −35° C. is 3000 mPa·s or less, wherein the lubricant base oil, to total mass of the composition, contains following components (A)˜(D):(A) 0.01˜10 mass % of ashless friction modifier;(B) 0.01˜0.2 mass % of phosphorus-containing anti-wear agent as phosphorous content;(C) 0.01˜1 mass % of metallic detergent as metal content; and(D) 0.01˜0.4 mass % of ashless dispersant having 3000˜20000 of weight-average molecular weight as nitrogen content.
