Abstract
A gas engine lubricating oil composition comprises an oil of lubricating viscosity including at least 90 mass % saturates and no more than 0.03 mass % to sulfur, a metal hydroxybenzoate detergent additive, a dispersant additive, and an aminic or phenolic antioxidant additive, and has a boron concentration, of zero or less than 90 ppm by mass, where boron, if present, is provided at least in part by a boron-containing dispersant additive. The composition exhibits improved lead corrosion properties and no adverse anti-wear properties.
