Mobil Pegasus 1005
Mobil Pegasus 1005 is a premium gas engine oil formulated using high-quality base stocks and advanced additive technology. It is designed to provide outstanding protection and performance in modern high-output, low-emission four-cycle gas engines, while also maintaining compatibility with older engine designs.
One of the key advantages of Mobil Pegasus 1005 is its excellent oxidation and thermal stability. The formulation resists degradation and nitration, helping extend oil life and reduce the frequency of oil changes. This contributes to lower operating costs and improved engine availability.
Mobil Pegasus 1005 also delivers outstanding engine cleanliness. Its detergent-dispersant system helps control carbon and varnish deposits in combustion chambers, pistons and heat exchangers, maintaining engine efficiency and reliability over extended operating periods.
Another important benefit is its strong wear protection. The oil helps protect critical components such as valve trains, pistons, liners and bearings, ensuring reliable performance under high load and high temperature conditions.
Mobil Pegasus 1005 also features low oil volatility. This helps reduce oil consumption and minimises deposit formation in exhaust systems, supporting longer catalytic converter life and reducing maintenance requirements.
The product is suitable for use in a wide range of gas engine applications including turbocharged and naturally aspirated engines, cogeneration systems and engines operating on natural gas or alternative fuels containing low levels of sulphur or chlorine. It is particularly suited for engines requiring low ash oils to protect emission systems.
Mobil Pegasus 1005 meets key OEM requirements including Caterpillar Energy Solutions TR 2105, MAN M 3271-2, Jenbacher, Wärtsilä and MTU approvals, making it suitable for use in demanding industrial and power generation applications.
Physical characteristics include a kinematic viscosity of approximately 121 mm²/s at 40°C and 13.4 mm²/s at 100°C, with a viscosity index of around 106. Mobil Pegasus 1005 has a density of approximately 0.855 g/cm³ at 15.6°C, a flash point of approximately 265°C and a pour point of approximately −25°C. It also features a sulphated ash content of approximately 0.5% and a base number of approximately 5.4 mg KOH/g, supporting reliable performance in gas engine applications.
