ExxonMobil cylinder oil approved for use in dual-fuel engines with methanol and LNG

ExxonMobil’s advanced 40BN cylinder oil, Mobilgard 540 AC, has now been validated by Swiss engine maker WinGD for use in its dual-fuel engines with conventional fuels, including methanol, and now LNG.

The American oil major said this oil was developed for use in slow-speed, two-stroke marine engines operating on fuels with up to 0.50% sulphur content, LNG, ethane, methanol and LPG. Mobilgard 540 AC has already been granted Category II status by MAN Energy Solutions for use in its two-stroke marine diesel engines. 

ExxonMobil claims the marine oil is suitable for methanol operation and with other liquid fuels with up to 1.5% sulphur levels.  

“Vessel operators need reliable, high-performance solutions,” explained ExxonMobil global technology program manager Yannis Chatzakis. “This double validation underscores ExxonMobil’s commitment to delivering both. As with all our cylinder oils, Mobilgard 540 AC has been developed using our balanced formulation approach. This helps ensure outstanding protection at optimum feed rates, supporting the peace of mind our customers need.”

Used in conjunction with a next-generation scrape-down oil analysis service like Mobil Cylinder Condition Monitoring, Mobilgard 540 is positioned to help deliver exceptional cleanliness with low-sulphur fuel due to a high level of detergency, combat deposits and scuffing-related engine wear associated with low-sulphur fuels and ensure performance in severe operating conditions as a result of excellent thermal and oxidative stability.

Mr Chatzakis said, “The next few years are likely to throw up new challenges as we collectively pursue a lower-emissions future. Our commitment to innovation will help achieve that goal.”
