Product Description

Shell Mysella S5 N 40 is a high-performance stationary gas engine oil specially developed for modern 4-stroke spark-ignition engines operating on natural gas. Formulated with advanced synthetic-technology base oils and a low-ash additive system (0.48% sulfated ash), it provides exceptional thermal and oxidation stability to deliver extended oil drain intervals. The lubricant resists nitration and viscosity increase, protecting against sludge buildup and keeping piston rings and liners remarkably clean. Its low-phosphorus formulation ensures complete compatibility with exhaust emission catalysts while effectively safeguarding spark plugs and valves against premature wear. Additionally, Shell Mysella S5 N 40 minimizes engine friction losses to optimize overall system efficiency and carries major OEM approvals from builders such as Caterpillar, INNIO Jenbacher, MWM, MAN, Waukesha, and Wärtsilä.
