Description
Mobil Pegasus 701 Series are premium-quality natural gas engine oils formulated with specially selected, high-stability base stocks. Designed to deliver excellent performance and operating economy, these lubricants are suitable for a wide range of gas engine types, operating conditions, and fuel qualities.
Mobil Pegasus 701 and Mobil Pegasus 701 SAE 30 are blended with ashless dispersants, oxidation and corrosion inhibitors, and anti-wear additives. This advanced formulation provides outstanding dispersancy, excellent high-temperature stability, and effective control of carbon and ash deposits, helping keep gas engines cleaner and more efficient.
The ashless dispersant technology helps prevent deposit buildup that can lead to engine detonation and reduced efficiency. By minimizing deposits, Mobil Pegasus 701 Series can extend port cleaning intervals in naturally aspirated and turbocharged two-cycle gas engines. The formulation also contributes to longer engine overhaul periods while extending the service life of oil filters and spark plugs.
Key Features and Benefits
1.Excellent Anti-Wear Protection: Mobil Pegasus 701 Series provides reliable protection against wear on critical engine components. It helps reduce scuffing and offers effective break-in protection for high Brake Mean Effective Pressure (BMEP) engines, promoting longer equipment life.
2. Superior Oxidation and Thermal Stability: The oil offers excellent resistance to oxidation and nitration, helping maintain cleaner engines, extend oil drain intervals, reduce filter replacement costs, and minimize the formation of harmful deposits.
3. Strong Corrosion Protection: Advanced corrosion inhibitors help protect bearings, valve guides, and internal engine components. This reduces wear, prevents rust-related damage, and extends maintenance intervals.
4. High-Quality Base Stocks: Premium base oils help reduce combustion chamber deposits that can cause detonation and power loss, supporting efficient engine performance and improved reliability.
Applications
Mobil Pegasus 701 Series is recommended for:
- Spark-ignited two-cycle and four-cycle gas engine crankcases and power cylinders.
- High-speed two-cycle gas engines.
- Modern slow-speed gas engines where special heavy-duty load-carrying performance is not required.
- Highly loaded four-cycle gas engines requiring anti-scuff protection.
- Reciprocating compressor cylinders compressing natural gas.
- Naturally aspirated and turbocharged gas engines operating at or above rated capacity under high-temperature conditions.
