Product Description

Shell Mysella S7 N Ultra 40 is a top-tier, ultra-extended-drain stationary gas engine oil specifically developed for the latest generation of highly rated 4-stroke spark-ignition engines running on natural gas. Formulated with advanced additive technology, it is optimized to withstand extreme mechanical and thermal stress, especially in modern high-output engines equipped with steel pistons and high Brake Mean Effective Pressure (BMEP) ratings. The lubricant offers up to double the oil life compared to previous-generation premium gas engine oils by providing exceptional resistance to oxidation, nitration, and harmful acid formation. Its low-ash, low-phosphorus (≤300 ppm) design prevents piston ring belt deposits and valve recession while remaining fully compatible with exhaust gas emission control catalysts. By minimizing internal friction and controlling viscosity increases over long operational cycles, it boosts overall power plant reliability and operational efficiency. The oil carries key OEM approvals for high-demand platforms, including INNIO Jenbacher (Type 6, 2, and 3 engines for Fuel Class A).
