Key data SAE: 30, 40; BN: 5.0; ash: 0.45%


Designed for Long Oil life

The longer the oil life, the less fluid maintenance is required to help your equipment to operate for longer without interruption. Shell Mysella S3 N is designed to have good oil life characteristics in high-speed four-stroke engines. In medium-speed four-stroke engines, its oil-drain interval can exceed 10,000 running hours.

Designed to Protect

Shell Mysella S3 N provides excellent valve seat protection and can thereby help to extend cylinder-head overhaul intervals. It also offers good combustion-chamber deposit control, as it produces low levels of ash of a favourable composition. It helps to keep ring grooves clean, which contributes to long ring and liner life, and can be used in installations equipped with an exhaust gas catalyst.

Designed for HIGH Efficiency

Shell Mysella S3 N is designed for excellent deposit control, which helps to prevent knocking and can unlock high levels of engine efficiency and availability. It is available in SAE30 grade for reduced friction and higher fuel efficiency
