Key Features:

Advanced Triple-Action Technology: Shell Alexia S5 (BN 80) and S6 (BN 100) incorporate this technology to:
- Acid Blocking: Prevents the formation of harmful acids that can cause corrosion.
- Acid Neutralization: Neutralizes acids to protect engine components.
- Smart Detergency: Maintains cleanliness of engine parts, reducing deposit formation.

Compatibility with Low-Sulphur Fuels: Shell Alexia S3 is specifically designed to meet the 0.1% fuel sulphur limit for Emission Control Areas, introduced in January 2015. It ensures optimal protection when using distillate fuels.
Reduced Piston Deposits: The reduced ash level of Alexia LS helps to avoid excessive piston top land deposits, which can sometimes build up when higher BN oils are used with low sulphur fuel.
Good Piston Ring and Port Cleanliness: Alexia LS contains “hidden” detergency, not reflected in the BN of the product. This enables it to keep the ring belt and scavenge air ports clean despite the reduced BN.
Greater Feed Rate Flexibility: The control of deposits and lower ash allows Alexia LS to be used over a wider range of feed rates with less danger of excessive deposits than a higher BN cylinder oil.

Applications:

Shell Alexia oils are suitable for a variety of marine engines, including:

Low-Speed Crosshead Diesel Engines: Particularly those burning low-sulphur fuels, where a lower Base Number (BN) oil is recommended to reduce the risk of sudden severe wear or scuffing.
MAN ES B&W Two-Stroke Engines: Recommended for all MAN ES B&W two-stroke engines Mark 8 and above using low (<0.5%) sulphur fuels, including VLSFO, ULSFO, distillate fuels, LNG, or biofuels.

Specifications & Approvals:

MAN ES B&W Two-Stroke Engines: Approved for use in all MAN ES B&W two-stroke engines Mark 9 and above; suitable for all MAN ES B&W two-stroke engines Mark 8 and lower engines (provided the recommendations in the engine type-specific guidelines are followed).

By choosing Shell Alexia, you ensure your marine engine operates with a lubricant that offers advanced protection, enhances engine reliability, and supports efficient onboard operations.
