Mobil Pegasus 705

Mobil Pegasus 705 is a Gas Engine Oil

Product Description

Mobil Pegasus 705 is a premium high performance SAE 40 gas engine oil formulated to lubricate a wide range of
natural gas fuelled engines. It is recommended for the newer stoichiometric and lean burn high-speed four-cycle
engines that are sensitive to valve face and seat wear. This oil is also recommended for the lubrication of the gas
compressors and wide range of engines requiring low ash oil. Pegasus 705 is formulated from select high quality,
mineral base oils and an advanced technology additive system engineered to provide excellent protection of engine and compressor components and reduced levels of combustion chamber deposits. It exhibits exceptional chemical stability and resistance to oxidation and nitration resulting in longer oil life and lower filter replacement costs. These performance advantages combined with outstanding detergency and dispersancy properties minimise the formation of ash and carbon deposits that could result in poor engine performance and detonation.

Pegasus 705 exhibits excellent anti-corrosion properties that prevent corrosive wear in cylinders, valve areas and
bearings resulting in longer engine life. Its high level of anti-wear performance reduces wear of rings, liners, and
bearings. It also provides exceptional valve seat and face protection and reduces the wear and deposit formation
in the critical valve guides of highly loaded turbocharged four-cycle engines.
