Cetus® PAG is a synthetic compressor oil based on polyalkylene glycol. It is designed for use in reciprocating compressors for chemical and hydro-carbon gases, including natural gases such as LNG and LPG. Because the solubility of these gases in Cetus PAG is low, the oil maintains its viscosity, unlike mineral oil base lubricants which will dilute.

Product description
Cetus® PAG Compressor Oil
The Cetus® PAG by Chevron is an advanced synthetic compressor oil specifically engineered for maritime industry applications. It is formulated from high-quality polyalkylene glycol and is ideal for reciprocating compressors handling a wide range of chemical and hydrocarbon gases, including natural gases like LNG and LPG. Unlike traditional mineral oil-based lubricants, Cetus PAG maintains its viscosity under the challenge of gas solubility, ensuring superior performance.
Performance Benefits
- Low gas solubility: Cetus PAG significantly reduces solubility of many gases compared to mineral-based oils, maintaining optimal viscosity and proper wear protection.
- Moisture tolerance: It accommodates up to 4%wt water content before hazing at 80°C, showcasing robust corrosion resistance even under humid conditions.
- Extended lubricant life: The formulation prolongs the life of the lubricant, reducing the need for frequent changes and enhancing operational efficiency.
- Inventory reduction: Its unique formulation resists butadiene dimerization and solid deposit formation, streamlining operations by negating the switch back to mineral-based oils.
Ideal Use Cases
Cetus PAG is recommended for use in the lubrication of cylinders and crankcase bearings in compressors dealing with a variety of gases such as methane, ethylene, ammonia, and more. Additionally, it is compatible with compressors from leading manufacturers like Howden, Linde AG, and Burckhardt Compression AG.
The product is compatible with standard seal and gasket materials, ensuring reliable integration into existing systems. However, maintaining dry gas conditions is vital for optimal performance, as Cetus PAG easily mixes with water, complicating maintenance when exposed to humid air.
