ExxonMobil Marine Fuels & Lubricants has launched Mobilgard 5100 cylinder oil, a product which has been formulated to mitigate the effects of cold corrosion in new design two-stroke marine engines operating on heavy fuel oil.

Mobilgard 5100 is a 100 BN cylinder oil which ExxonMobil has developed in collaboration with leading marine engine builders.

The new product has been formulated to address the problem of cold corrosion, which occurs when the engine's cylinders operate at conditions below the acid dew point, creating the potential to cause significant liner wear.

Aaron Cobb, director, ExxonMobil Marine Fuels & Lubricants, commented: "Many ship operators are facing poor cylinder liner life due to cold corrosion in both new fuel-efficient engines and earlier designs that have been fuel optimized for part load operation.

"We developed Mobilgard 5100 using an advanced, scientifically engineered ‘balanced formulation approach’ that leverages ExxonMobil’s leading technology and application expertise. Mobilgard 5100 delivers exceptional acid neutralization performance, deposit control and oxidation stability to help mitigate cold corrosion, optimize feed rates and, ultimately, control costs."

Mobilgard 5100 joins Mobilgard 560 VS and Mobilgard 570 as the latest addition to ExxonMobil’s range of cylinder oils, with each product specifically engineered to help ship operators increase vessel reliability and reduce operating costs.
