Abstract: A low sulfate ash lubricating oil composition comprising an oil of lubricating viscosity, 0.1 to 3.0 % of a calcium overbased acidic material, 0.1 to 2.0 % of a magnesium overbased acidic material, and at least 0.5% of a combination of an alkylene-coupled hindered phenol antioxidant and an antioxidant other than an alkylene-coupled hindered phenol antioxidant, is particularly useful for lubricating stationary gas engines.

Abstract: This invention relates to a lubricating oil composition, comprising: (A) a base oil and (B) a boron-containing compound represented by the formulae wherein in Formulae (B-I), (B-II) and (B-III), each R is independently an organic group and any two adjacent R groups may together form a cyclic group; the lubricating oil composition containing sulfur, boron and optionally phosphorus with the ratio of sulfur to boron to phosphorus being represented by the formula S1+5B1+3P1>0.35 wherein S1 is the concentration in percent by weight of sulfur in the composition, B1 is the concentration in percent by weight of boron in the composition, and P1 is the concentration in percent by weight of phosphorus in the composition; the concentration of sulfur in the lubricating oil composition being from about 0.01% to about 0.25% by weight; the concentration of phosphorus in the lubricating oil composition being up to about 0.08% by weight.

Abstract: A composition of an oil of lubricating viscosity, an antioxidant, an anti-nitration agent, and optionally a borated product of an epoxide or the reactive equivalent of an epoxide, provides a desirable lubricant for diesel or natural gas-fueled engines. The composition is substantially free from metals and preferably substantially free from phosphorus. The amount of the antioxidant the antinitration agent are sufficient to reduce the amount of varnish formation in a natural gas engine.
