Mobil Pegasus 505 Series

Gas Engine Oil

Mobil Pegasus™ 505 Series are natural gas engine oils formulated exclusively from specially selected base stocks of high stability. These lubricants provide the excellent performance and economy for a wide variety of engine types, service severity and fuel qualities.

Mobil Pegasus 505 and 505 SAE 30 utilize advanced technology to provide excellent detergency/dispersency protection characteristics along with high-temperature anti-scuff and anti-scoring protection. These oils contain ashless and metallic detergents and are fortified with oxidation inhibitors and antiwear agents. Their use helps minimise carbon and ash deposits.

Mobil Pegasus 505 Series oils combat corrosive wear in cylinders and bearings by neutralising acids. They will also minimize wear of rings, liners and bearings and will help curtail wear in valve seats of turbocharged, four-cycle gas engines. These oils provide good engine cleanliness and filter life.
