The Importance of Monitoring Lubricant Metal Levels in Stationary Natural Gas Engine Oil Applications
Stationary Natural Gas Engine Oils (NGEOs) are generally categorized by their levels of sulfated ash. Sulfated ash is the residue left behind after the oil is burned and consists of the metallic based additives in the oil. The reason NGEOs are categorized by sulfated ash content is because natural gas engines rely on these ash deposits to cushion the valves to prevent valve recession. This white paper outlines condition monitoring strategies for extending oil drains.
