Formulated to meet needs of newer engines 

ExxonMobil said its Mobilgard 540 AC, a premium 40BN marine cylinder oil, was granted Category II status by MAN ES for use in their Mark 9 and higher 2-stroke marine engine designs.

The lubricant, which has been formulated to deliver advanced cleanliness to meet the needs of these newer engines, has received a No Objection Letter from the engine builder following extensive field demonstrations.

“Mobilgard 540 AC is one of the first 40BN lubricants to be granted Category II status,” said Yannis Chatzakis, Global Marine Technology Program manager at ExxonMobil. “As the latest addition to the MobilGard family of cylinder oils, it builds on the brand’s extensive heritage of innovation, performance and reliability, helping provide peace of mind to vessel operators in a wide variety of operating conditions.”

ExxonMobil said its balanced formulation methodology is designed to ensure that Mobilgard 540 AC helps vessel operators wishing to simplify lubricant management through use of a single, low BN Category II cylinder oil. Operators can gain further confidence in the level of their engine’s reliability through implementation of an onboard scrape down oil analysis program, such as Mobil Serv Cylinder Condition Monitoring.

The high-performance cylinder oil will be available to order from the third quarter of 2022 in key locations from ExxonMobil’s extensive network of more than 650 ports throughout the world.
