Mobil Pegasus™ 610 Ultra is a high performance natural gas engine oil primarily intended for the lubrication of modern medium and high speed four-cycle engines operating on fuel that contains corrosive materials such as hydrogen sulphide or halogens (compounds containing chlorine, fluorine, etc.). This product is specially developed to cope with aggressive gases with high levels of hydrogen sulphide which significantly limits the oil drain intervals and with high levels of siloxanes whose abrasive effects once burnt can significantly increase wear and reduce engine life.

Mobil Pegasus™ 610 Ultra is a 1.0% sulfated ash, high Total Base Number (TBN) gas engine oil with exceptional reserve alkalinity designed to offset the negative effects of these corrosive materials on engine components. Mobil Pegasus™ 610 Ultra provides excellent anti-wear and especially anti-scuff performance assuring minimal piston scuffing, scoring and cylinder and ring wear. This product can also be used for the lubrication of the reciprocating compressors in landfill and biomass gas applications. Mobil Pegasus™ 610 Ultra has a high level of wear protection which helps reduce the scuffing of the liners and extend the overhaul periods and significantly longer operating period.
