IMO 2020 Compliance — 0.50% Sulphur Fuel

Specifically engineered for vessels operating under the IMO 2020 global 0.50% sulphur cap — combating deposit build-up and scuffing-related engine wear issues that are specifically associated with the use of 0.50% sulphur fuels.

Balanced 40 BN Formulation

40 BN level provides both excellent acid neutralisation to neutralise combustion acids from 0.50% sulphur fuel AND outstanding engine cleanliness — the balance that is critical for preventing both corrosive wear and deposit build-up simultaneously.

Optimum Viscosity — 20 cSt @ 100°C

Optimum viscosity ensures excellent lubricant distribution and oil film retention — protecting engine parts throughout the cylinder stroke and maintaining oil film at elevated peak firing pressures and liner temperatures in modern high-efficiency crosshead engines.

Excellent Thermal & Oxidative Stability

Ensures performance in a wide range of engine operating conditions — maintaining oil integrity at the elevated temperatures and pressures found in modern two-stroke crosshead engines operating at reduced cylinder oil feed rates.

ULSFO Compatible with OEM Guidance

Suitable for ultra-low sulphur fuel oil (<0.10%S) operation in conjunction with OEM guidance — giving fleet operators flexibility to use a single cylinder oil across multiple fuel grades where OEM permits.

Validated by WinGD & MAN ES

Passed stringent fit-for-use testing and extensive field trials meeting OEM requirements for both WinGD and MAN Energy Solutions — the world's two dominant slow-speed two-stroke crosshead engine manufacturers.
