SPONSOR PRESS RELEASE: ExxonMobil launches Mobil Pegasus™ 610 Ultra oil for modern medium- and high-speed four cycle gas engines

ExxonMobil launches Mobil Pegasus™ 610 Ultra oil for modern medium- and high-speed four cycle gas engines

Lubricant is specially formulated to operate with
and biogases containing high levels of corrosive materials

  • Outstanding anti-wear properties help reduce unscheduled maintenance
  • Extended oil drain intervals even when running fuel with corrosive content
  • Formulated in collaboration with Infinis, a leading UK renewable power generator

Birmingham 3rd July, 2019 – Today at UK AD and World Biogas Expo 2019, 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% sulfated 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,” said 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,” said 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.”
