ExxonMobil has announced the launch of
Mobilgard 300 C, a "high-performance", "next-generation" system oil for two-stroke, crosshead marine diesel engines operating under severe conditions. Compared with conventional system oils, Mobilgard 300 C is said to offer superior engine cleanliness, better engine protection and longer oil life.
Formulated with a unique detergent system, Mobilgard 300 C is designed to deliver enhanced crankcase cleanliness, which helps to prevent the buildup of piston undercrown deposits.
According to ExxonMobil, the new system oil performs well even in the presence of moderate amounts of contamination by cylinder oil or heavy fuel oil while its anti-wear additive system is said to provide "excellent protection" for highly loaded engine parts such as gear drives and bearings.
In a statement,
Iain White, Global Marine Marketing Manager for ExxonMobil, said: "Mobilgard 300 C is a high-performance system oil that is formulated to optimise the performance and extend the life of slow-speed marine engines. It has been developed with a proprietary detergent system to ensure it delivers enhanced engine cleanliness and helps vessel operators increase reliability and reduce operating costs."
The oil is specifically designed with an additive package to ensure high temperature oxidation resistance, making it less susceptible to viscosity thickening and deposits. In addition, ExxonMobil says Mobilgard 300 C provides "excellent demulsibility performance", enabling the oil to easily separate from water helping to prevent poor lubricity, corrosion and rust in the engine.
Mobilgard 300 C has been approved for use in the latest design engines from Man Diesel & Turbo and Wärtsilä.
Alongside Mobilgard 300 C, ExxonMobil has a range of Mobilgard cylinder oils to help optimise the performance of two-stroke engines. This includes MobilgardTM 5100, a high-performance cylinder oil specially formulated to mitigate cold corrosion in new design two-stroke marine engines operating on heavy fuel oil.
