摘要： A biodegradable lubricating oil composition especially useful as a gear oil employs a synthetic alcohol ester basestock formed from mono- and dipentaerythritol with certain mono- and dicarboxylic acids or dicarboxylic acid anhydrides and an effective amount of a polyoxyalkylene alcohol demulsifying agent, a combination of alkylated organic acid and ashless succinimide rust inhibitors and an ashless dithiocarbamate antiwear and extreme pressure agent.
