Servo NGE 40 is a high-performance natural gas engine oil specially designed for modern stationary gas engines operating on natural gas, biogas, or landfill gas. It is formulated from premium-quality, high-purity base oils and advanced additive technology that delivers superior control over oxidation, nitration, and valve wear — the three major challenges in gas engine lubrication. Servo NGE 40 ensures reliable protection and cleanliness of critical components, guaranteeing consistent performance and reduced maintenance across extended operating hours. Developed with enhanced detergent-dispersant chemistry, Servo NGE 40 keeps pistons, liners, and valve areas remarkably clean by effectively controlling carbon and ash deposits. Its optimized low-ash formulation prevents valve torching and spark plug fouling, ensuring smooth engine operation and prolonged spark plug life. The lubricant’s high thermal and oxidative stability prevents oil thickening and deposit formation even under continuous high-load and high-temperature service conditions. This results in a stable viscosity profile and consistent lubrication film throughout the oil’s service life. Servo NGE 40’s balanced additive system provides robust anti-wear and anti-corrosion protection, shielding metallic surfaces against rust, oxidation, and acid attack caused by combustion by-products. The oil’s strong base retention capacity neutralizes harmful acidic compounds, maintaining the alkalinity necessary for corrosion control and long drain intervals. Its excellent oxidation stability extends oil life significantly, allowing for reduced oil top-ups and lower operational costs. This advanced gas engine oil is ideally suited for stationary engines in power generation, cogeneration (CHP) systems, and industrial compressors fueled by natural gas, CNG, or biogas. The oil meets the demanding requirements of modern lean-burn and stoichiometric combustion systems, offering cleaner combustion, longer service life, and reduced exhaust emissions. Servo NGE 40 also provides superior compatibility with exhaust after-treatment devices, maintaining their efficiency over extended service periods. The lubricant’s robust formulation minimizes valve recession, reduces piston ring wear, and ensures better sealing performance. Its exceptional oxidation and nitration resistance allows it to withstand high combustion temperatures while maintaining effective lubrication and film strength. Furthermore, Servo NGE 40 provides smooth cold start-up performance and consistent film thickness during operation, ensuring complete protection even under intermittent load conditions. In summary, Servo NGE 40 is a next-generation natural gas engine lubricant that combines enhanced oxidation resistance, reduced ash content, and excellent anti-wear characteristics to deliver dependable, long-term engine protection. It supports cleaner combustion, longer drain intervals, and improved reliability, making it the preferred choice for industries seeking a high-performance, low-maintenance solution for stationary gas engines.
