Servo Pride GEO 20W-50 is a premium-quality low-ash gas engine oil designed for high-performance commercial vehicles operating on CNG, LPG, and other natural gas fuels. Formulated from highly refined mineral base oils and a carefully selected additive package, this lubricant provides exceptional oxidation stability, outstanding resistance to nitration, and superior thermal protection even under extended operating conditions. Its advanced formulation minimizes engine deposits and wear, ensuring smooth operation and longer engine life. Engineered to deliver excellent protection against corrosion and valve seat wear, Servo Pride GEO 20W-50 maintains clean piston rings and combustion chambers, ensuring consistent engine efficiency and power output. The oil’s high viscosity index ensures stable lubrication across a wide temperature range, while its superior film strength prevents metal-to-metal contact in high-load, high-temperature environments. This makes it ideal for modern heavy-duty gas engines requiring reliable performance and extended drain intervals. Servo Pride GEO 20W-50 is approved by Ashok Leyland Ltd. for use in their commercial vehicles operating on CNG, with an oil change interval of up to 10,000 kilometers under recommended conditions. It meets the demanding CES 20074 specification of Cummins USA, reflecting its world-class performance and reliability. This oil is the perfect choice for fleet operators seeking enhanced durability, reduced maintenance costs, and improved overall engine efficiency in gas-powered commercial vehicles.
