ExxonMobil has announced the launch of Mobil Pegasus™ 610 Ultra, a high-performance lubricant formulated for use in modern medium- and high-speed four cycle gas engines operating on fuels containing corrosive materials such as hydrogen sulphide and halogens.

The oil was developed and tested in collaboration with Infinis, one of the UK’s largest renewable power generators.

Landfill and biogases often include high levels of hydrogen sulphide, which can significantly limit the oil drain intervals of gas engine lubricants, and siloxanes, which can considerably increase wear and reduce engine component life.

Mobil Pegasus 610 Ultra is a 1.0% sulphated ash, high BN oil with exceptional reserve alkalinity, specifically developed to withstand the effects of aggressive gases by neutralising acids, offsetting their effects on engine components while reducing the need for decoking.

The lubricant’s excellent oxidation and chemical stability help extend oil drain intervals, reduce unscheduled maintenance costs and increase overall engine availability.

“Our partnership with Infinis has allowed us to more deeply understand the application issues that customers face, in order to develop the right solution,” says Elisabetta Scossa, Europe Energy Manager, Industrial Lubricants – ExxonMobil. “The result, Mobil Pegasus 610 Ultra, should not only help to enhance productivity across landfill and biogas operations, but also improve engine reliability.”

“This collaboration has proved to be highly constructive,” says Stewart Wilson, Centre of Excellence Manager, Infinis. “By utilising our close working relationship and pairing our detailed knowledge of gas engine operations with ExxonMobil’s lubricant expertise we have been able to create an oil that possesses a range of significant benefits for our business.”
