Typical characteristics

Manufacturer's description

Mobil Pegasus 610 Ultra is a high-performance gas engine oil designed for the lubrication of modern medium- and high-speed four-cycle engines operating on landfill, biomass or other fuels containing corrosive contaminants such as hydrogen sulphide or halogens. It is a 1.0% sulfated ash, high Total Base Number (TBN) SAE 40 formulation with exceptional reserve alkalinity that offsets the corrosive effects of these contaminants, and it can also be used to lubricate reciprocating compressors in landfill and biomass gas service. The oil delivers outstanding anti-wear and anti-scuff performance, minimising piston scuffing, scoring, and cylinder and ring wear, while its excellent oxidation and chemical stability keep engines cleaner and support extended oil drain intervals even with highly contaminated fuel. Effective corrosion resistance protects valve guides, bearings and other internal components, helping reduce liner scuffing and extend overhaul periods. Mobil Pegasus 610 Ultra is approved to MAN M 3271-4, Caterpillar Energy Solutions TR 2105 (CG132, CG170, CG260), MWM TR 0199-99-2105, INNIO Jenbacher TI 1000-1109 (Class B and C fuel gas, Type 2 & 3), and is suitable for Rolls-Royce Solutions Augsburg (former MTU Onsite Energy) Series 400 gas engines without SCR catalyst operating on biogas. Typical properties include a kinematic viscosity of 12.9 mm²/s at 100°C, viscosity index 107, and a base number of 10.3 mg KOH/g.

Applications

• Gas engines operating on fuel containing moderate to high levels of hydrogen sulphide (H2S) and high levels of siloxanes, which turn to silicon dioxide during combustion, 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 containing sulphur or halogens.
• High-output or naturally aspirated engines operating at or above rated capacity under high temperatures.

Performance & benefits

• High TBN and reserve alkalinity control wear and corrosion when using contaminated gas, protect valve seats and faces on four-stroke engines, control combustion-chamber ash formation and improve spark-plug performance.
• Outstanding anti-wear and anti-scuff properties reduce wear of engine components, reduce scuffing of liners in highly loaded gas engines and provide excellent break-in protection.
• Excellent oxidation and chemical stability keep engines cleaner, extend oil-drain intervals even with highly contaminated fuels, reduce oil-filter costs and give excellent resistance to oxidation and nitration.
• Effective corrosion resistance reduces valve-guide wear in four-stroke gas engines and protects bearings and internal components.
