Mobil Pegasus 801 - SAE 30

The Mobil Pegasus 801 - SAE 30 is the latest generation of ashless detergent and anti-scuff gas engine oil formulated from highly refined base oils and an advanced technology additive system. It is engineered to provide a high level of chemical and thermal stability resulting in cleaner engines and higher engine performance. Mobil Pegasus 801 - SAE 30 provides exceptional cleanliness and optimum wear protection in the most severe applications, without the disadvantage of increased ash deposits.

Features and Benefits

Mobil Pegasus 801 - SAE 30 provides outstanding performance in both two- and four-cycle gas engines making it a good choice for all applications where ashless and low-ash oils are recommended. It's advanced additive system protects high BMEP engines against scuffing, scoring and wear particularly during critical break-in periods. The result is long engine life and low maintenance costs. Mobil Pegasus 801-30 has demonstrated outstanding performance over an exceptionally wide range of engines and operating conditions. Where mixed engines are in service Mobil Pegasus 801 - SAE 30 provides a single product which simplifies inventory and reduces the potential for product misapplication.

Features	Advantages and Potential Benefits
Outstanding Oxidation Stability	Longer engine and oil life Cleaner engines Extended filter life
Advanced Technology Very Low Ash Formulation	Lower levels of port carboning (two-cycle engines) Reduced valve and combustion chamber ash and carbon build-up Longer spark plug life
Outstanding Anti-wear and Anti-scuff Protection	Less engine wear Increased engine life Excellent break-in protection for high BMEP engines
Exceptional Nitration Resistance	Less engine sludging Improved filter life Reduced engine deposits
High Level Corrosion Protection	Protects engine components against corrosive wear Longer engine life and lower maintenance costs

• Mobil Pegasus 801 - SAE 30 is recommended for the lubrication of the crankcase, power cylinders, and compressor cylinders of spark-ignited, two- and four-cycle gas engines operating on clean fuel.
• Ideal for engines that drive generators for power production or gas compressors in gathering, transmission, storage, and distribution of natural gas.
• Ebulliently cooled gas engines
• Engines in remote locations which operate virtually unattended for long periods. In many cases, the engines are operated at, or in excess of full-rated output, while other applications are intermittent or stand-by service. Reliability, is therefore essential.
• Mobil Pegasus 801 - SAE 30 shows excellent results in multipurpose applications, particularly involving highly turbocharged engines requiring anti-scuff protection for cylinder liners and piston skirts.
• When natural or petroleum gas is being compressed and is dry and free of suspended liquids or corrosive components, the compressor cylinders usually are lubricated with the same oil as the engine crankcase. Mobil Pegasus 801 - SAE 30 has been successful in this service.
