Shell Alexia S3

Living With Low Sulphur

Effective January 2015, MARPOL regulations state that vessels entering Emission Control Areas (ECA) will need to reduce their fuel sulphur level to a maximum of 0.1% or limit their sulphur emissions.1
This will help to reduce the environmental impact of shipping and improve air quality. However, shipping companies will have various options for compliance with the regulations. Shell Marine Products has designed its product portfolio to cater for its customers’ various needs, depending on their preferred compliance option.


Shell Alexia S3 is a BN 25, SAE 50 viscosity grade oil dedicated for low-speed, two-stroke diesel engines entering ECAs. It is formulated for use in engines burning low sulphur fuels including marine gas oil and distillate fuels fuel oil with up to 0.5% sulphur.


Shell Alexia S3 oil is specifically designed to protect your engines from wear and deposits when using low‑sulphur fuels offer excellent cleanliness.


Shell Alexia S3 is validated for use by major engine manufacturers including MAN Diesel & Turbo Wärtsilä.
1 The International Maritime Organisation (IMO) is a United Nations agency formed to promote maritime safety. IMO ship pollution rules are contained in the “International Convention on the Prevention of Pollution from Ships”, known as MARPOL 73/78. In 1997, a protocol was adopted to amend the convention and a new Annex VI titled “Regulations for the Prevention of Air Pollution from Ships” was added which entered into force on 19 May 2005.
MARPOL Annex VI sets CO2, NOx and SOx emissions limits from ship exhausts, and prohibits deliberate emissions of ozone-depleting substances.
