TotalEnergies Lubmarine has launched Aurelia FE, a marine engine oil it says is designed to improve fuel economy in four-stroke medium-speed engines, with laboratory testing indicating fuel savings of 1.5% on a standardised IMO E3 cycle — a methodology independently approved by Bureau Veritas.

According to to the French lube supplier, field testing points to the potential for greater savings under real-world operating conditions, which would translate into lower fuel costs and reduced CO₂ emissions. The weighted average saving is measured against an equivalent reference lubricant across the IMO E3 cycle (NOx Technical Code).

Lubmarine says Aurelia FE can be deployed without any equipment modifications, vessel downtime or operational disruption. The product is said to have accumulated more than 100,000 hours of service experience and to have received approval from a marine engine original equipment manufacturer — described as the first approval of its kind for an engine oil in this category.

Louise Tricoire, vice-president of TotalEnergies Lubmarine, stated: "At Lubmarine, we are committed to developing solutions that create value for our customers while supporting the shipping industry's decarbonisation. Aurelia FE represents an important step forward in lubricant innovation, helping shipowners improve fuel efficiency and reduce emissions without compromising engine performance and reliability."
