Product Description

Mobil Pegasus™ 610 Ultra is a high performance gas engine oil primarily intended for the lubrication of modern medium and high speed four-cycle engines operating on landfill, biomass or other 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™ 610Ultra 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.

Features and Benefits

Mobil Pegasus™ 610 Ultra gas engine oil provides an additional level of protection in those applications using highly contaminated fuel where piston scuffing, high deposit formations and very short drain interval were observed.

Applications

Gas engines operating on fuel that contains moderate to high levels of hydrogen sulphide (H2S) and high levels of siloxanes which turn to silicon dioxide in the combustion process causing significant deposits and liner wear.

Engines operating on fuel containing other corrosive components such as TOHCl (Total Organic Halides as Chloride)

Reciprocating compressors operating on natural gas that contains sulphur or halogens

High output or naturally aspirated engines operating at or in excess of rated capacity under high temperatures
