Features and Benefits
Mobil Pegasus 701 Series gas engine oils provide cleaner engines, long oil and filter life, and low lube oil consumption. The result is the potential for extended engine life and reduced overhaul costs.
| Features | Advantages and Potential Benefits |
| Good Anti-wear Properties | Lower wear of engine components
Provides good break-in protection of high BMEP engines |
| Good Oxidation and Bulk Oil Stability | Cleaner engines
Extended drain intervals
Reduced filter costs
Good resistance to oxidation and nitration
Reduces coking and formation of undercrown deposits |
| Good Corrosion Resistance | Reduces valve guide wear in four-cycle gas engines
Protects bearings and internal components
Reduced port blockage, with longer intervals between cleaning |
| High Quality Basestocks | Less power loss from detonation caused by combustion chamber deposits |
Applications
- Crankcases and power cylinders of spark-ignited two- and four-cycle gas engines
- High speed two-cycle gas engines
- Suitable for use in modern two-cycle and four-cycle slow-speed gas engines except where severity of application requires special heavy-duty, load-carrying performance
- Highly loaded 4-cycle engines requiring anti-scuff protection
- Reciprocating compressor cylinders compressing natural gas
- High output or naturally aspirated turbocharged engines operating at or in excess of rated capacity under high temperatures
