ExxonMobil Marine Fuels and Lubricants has launched its own 100BN cylinder oil, Mobilgard 5100, which the company says id designed to mitigate the effects of cold corrosion in new design two-stroke marine engines operating on HFO.

Mobilgard 5100 joins Mobilgard 560 VS and Mobilgard 570 in the ExxonMobil low-speed cylinder oil range, each product claimed to be specifically engineered to help ship operators increase vessel reliability and reduce operating costs.

Mobilgard 5100 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. According to ExxonMobil, the new oil has received a full ‘No Objection Letter’ from MAN Diesel & Turbo.

“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 optimised for part load operation,” said Aaron Cobb, director, ExxonMobil Marine fuels and lubricants. “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 neutralisation performance, deposit control and oxidation stability to help mitigate cold corrosion, optimise feed rates and, ultimately, control costs.”

Mobilgard 5100 follows ExxonMobil’s recent upgrade of its two-stroke engine condition monitoring programme, MobilGard Cylinder Condition Monitoring (CCM). This includes scrape down oil analysis, as advocated by the major engine builders, to provide on-board comparison of oil samples against ExxonMobil’s database of nearly 100,000 test results.
