Marvell Gassuz 805 SAE 40 Low Ash Gas Engine Oil

Premium High-Performance Lubricant for Modern Four-Stroke Stationary Gas Engines

Product Overview

Marvell Gassuz 805 SAE 40 is a low-ash, high-performance gas engine oil specifically formulated for use in modern four-stroke stationary gas engines operating under demanding service conditions. This premium mineral-based lubricant is engineered to provide exceptional engine cleanliness, oxidation stability, nitration resistance, and wear protection in engines fueled by natural gas, biogas, landfill gas, or sour gas.

Ideal for use in cogeneration (CHP) units, industrial gas compressors, and power generation applications, Gassuz 805 is formulated using high-quality base oils combined with an advanced additive system designed to meet or exceed the performance requirements of leading global OEMs. It offers extended oil drain intervals, improved spark plug life, and optimum protection for valve train components—making it the ideal lubricant solution for operators seeking operational reliability, low maintenance costs, and regulatory compliance with emission standards.

Key Features and Benefits

1. Low Ash Content for Emissions Compliance

Marvell Gassuz 805 features a carefully controlled low ash formulation (~0.5% sulfated ash) to ensure compatibility with catalytic converters and sensitive exhaust aftertreatment devices. This prevents ash accumulation in combustion chambers and protects catalyst substrates, especially in lean-burn engines where emission regulations are strict.

2. Superior Oxidation and Nitration Resistance

This oil resists thermal breakdown and chemical degradation from prolonged high-temperature operation, which is common in stationary engines running at constant loads. Its advanced oxidation inhibitors and base oil quality allow for extended oil change intervals, thereby reducing downtime and improving engine productivity.

3. Advanced Anti-Wear Technology

Gassuz 805 forms a durable lubricating film that protects pistons, liners, camshafts, and bearings from wear. This is crucial for equipment operating continuously under full load, particularly in high-output gas engines with turbocharging and high compression ratios.

4. Enhanced Valve Train Protection

The oil’s balanced detergency and dispersancy system provides protection against valve seat recession and wear, which are common issues in gas engines—especially those operating with fuel containing minimal lubricating properties.

5. Improved Engine Cleanliness

Marvell Gassuz 805 controls carbon and varnish deposits, ensuring clean spark plug operation, longer component life, and better combustion efficiency. Its superior detergency also helps maintain a cleaner crankcase environment and reduces filter clogging.

6. High Thermal and Shear Stability

Maintains its viscosity and protective film under thermal stress and mechanical shearing, which helps ensure consistent lubrication performance over long operating cycles.
