Product description

Mobil Pegasus SR
Gas Engine Oil Scuff Resistant

Mobil Pegasus SR is a high performance gas engine oil specifically developed for the lubrication of modern medium and high-speed, four cycle engines operating on aggressive gases typically containing high levels of Siloxanes, where high wear or scuffing is a significant issue. These engines are generally of the lean-burn, turbo charged design, where increased manifold pressures and reduced emission requirements lead to reduced amounts of lubricant available on liner surfaces, and in the valve guide areas.
Mobil Pegasus SR provides outstanding anti-wear and anti-scuff performance which helps assure minimal piston scuffing, and low cylinder liner and piston ring wear. The Mobil Pegasus SR is a 0.5% ash gas engine oil with exceptional reserve alkalinity designed to offset the detrimental effects of acidic attack on engine components. The excellent corrosion protection properties helps prevent corrosive wear in cylinders, valve areas, and bearings which can result in longer engine life, and lower maintenance costs. This oil can be used for the lubrication of the reciprocating compressors in landfill and biomass gas applications.

Features :
- Outstanding Anti-wear and Anti-scuff Properties
- Optimised TBN and Reserve Alkalinity
- Excellent Oxidation and Chemical Stability
- Effective Corrosion Resistance
- Exceptional Detergent / Dispersant Properties

Applications :
- Gas engines operating on gas that contains moderate levels of hydrogen sulphide (H2S)
- Engines operating on gas containing other corrosive materials such as TOHCI (Total Organic Halides as Chloride), landfill or biomass gases. Particularly recommended for gas containing moderate or high level of siloxanes.
- Spark ignited four-cycle gas engines with very low lube oil consumption - Engines experiencing valve train wear and corrosion
- Light output or naturally aspired engines operating at or in excess of rated capacity under high temperatures

Specifications : - Approved from DEUTZ for engines operating with all gases with low contamination
- Jenbacher approval for landfill
