摘要： A lubricating oil composition for a continuously variable transmission which comprises (A) a base oil comprising a hydrocarbon compound having a cohesive energy density at 40°C of 0.180 GPa or more and having a kinematic viscosity at 40°C of 5 to 150 mm /s and, added to the base oil, one or more combinations selected from (B) a phosphoric acid ester having an alkyl group containing a thioether bond and/or (C) a phosphoric acid ester and an amine salt thereof, and an overbased calcium sulfonate. The above lubricating oil composition can improve the power transmission capacity of various types, such as a metal belt type, a chain type and a traction drive type of CVT and also can sustain the improved power transmission capacity.

摘要： A lubricating oil composition for internal combustion engines which comprises a base oil, (a) an ashless dispersant containing boron, (b) a metallic detergent, and optionally (c) at least one selected from a group consisting of esters of aromatic carboxylic acids having hydroxyl group and hydroxy compounds and compounds containing boron which are derived from the esters, wherein a ratio ÄBÜ/ÄMÜ of a content of boron ÄBÜ in the composition in % by weight to a total content of metals ÄMÜ derived from the detergent in the composition in % by weight is not less than 0.15, and a sulfated ash content in the composition is not more than 1.5 % by weight. The lubricating oil composition has a low ash content, does not show adverse effects on the performance of apparatuses for exhaust gas treatment, and exhibits excellent resistance to coking and oxidation stability.
