👉 The Commissioners' Fluid, also known as the Commissioners' Oil or simply the Commissioners' Petroleum, is a synthetic lubricant developed in the early 20th century by the U.S. government's Bureau of Standards (now known as the National Institute of Standards and Technology) in collaboration with private industry. It was created to address the limitations of crude oil-based lubricants, which were prone to contamination and instability. The fluid is a complex mixture of hydrocarbons, including paraffins, naphthenes, and aromatics, stabilized with additives like antioxidants and detergents to enhance its performance. Commissioners' Fluid was widely used in machinery, engines, and industrial applications due to its superior viscosity stability, low volatility, and resistance to oxidation, making it a crucial advancement in lubrication technology.
