Abstract

Lubricant compositions may provide corrosion resistance, oxidation resistance, and reduced wear for hydraulic systems. A lubricant composition may comprise an ashless dithiophosphate in an amount sufficient to provide a concentration of phosphorus ranging from 10 ppm to 250 ppm to the lubricant composition, a metal dialkyl dithiophosphate such as zinc dialkyl dithiophosphate (ZDDP) in an amount sufficient to provide a concentration of phosphorus ranging from 50 ppm to 1000 ppm to the lubricant composition, a corrosion inhibitor comprising an alkyltriazole derivative in an amount sufficient to provide a concentration of nitrogen ranging from 0.75 ppm to 100 ppm to the lubricant composition, and a major amount of a base oil.
