Product catalog summary
Product Description: Mobil Pegasus™ 801 is a premium SAE 40 gas engine oil designed for low, medium, and high-speed gas engines where low ash or ashless oils are recommended. It ensures engine cleanliness by preventing carbon and ash deposits and reduces engine wear, extending maintenance intervals.
Features and Benefits: The oil offers outstanding performance in two- and four-cycle engines, protecting against scuffing and wear, especially during break-in periods. It provides oxidation stability, reducing engine deposits and extending engine and oil life. The advanced low ash formulation minimizes carbon build-up, prolongs spark plug life, and offers excellent anti-wear protection, enhancing engine longevity.
Applications: Suitable for lubricating crankcase, power cylinders, and compressor cylinders in spark-ignited gas engines. Ideal for engines in power production, gas compression, and remote locations. It performs well in turbocharged engines requiring anti-scuff protection.
Specifications and Approvals: Recommended for applications needing ashless or low-ash oils, offering anti-scuff protection across various engine designs.
Typical Properties: SAE Grade 40 with a viscosity of 125 cSt at 40º C and 13.2 cSt at 100º C. It has a viscosity index of 97, a pour point of -15º C, and a flash point of 249º C.
Health and Safety: The product is not expected to have adverse health effects when used as intended. Disposal should be environmentally conscious, and MSDS is available upon request.

Mobil Pegasus™ 801-1

Mobil Pegasus™ 801 Mobil Industrial , United States Gas Engine Oil Product Description Mobil Pegasus™ 801 is an SAE 40 premium performance gas engine oil intended for the lubrication of all classes of gas engines operating at low, medium and high speeds where low ash or ashless oils are recommended. It provides outstanding engine cleanliness and performance by helping to prevent the formation of carbon and ash deposits on pistons, in ring belt areas, on exhaust and intake ports, on valves and valve stems and in combustion chambers. Mobil Pegasus 801 also reduces the potential for port carboning of two-cycle gas engines. It minimizes engine wear and protects valve faces, seats and guides of turbocharged, four-cycle engines. Mobil Pegasus 801 provides exceptional protection against scuffing in demanding engine applications and also provides excellent protection against corrosion of internal engine components. Filter and oil life can be extended and the high performance capability of the Mobil Pegasus 801 can also help to extend the time between engine maintenance and overhaul periods. The Mobil Pegasus 801 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 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 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. This performance can help to provide long engine life and low maintenance costs. Mobil Pegasus 801 has demonstrated outstanding performance over an exceptionally wide range of engines and operating conditions. Where mixed engines are in service Mobil Pegasus 801 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 Improved ring, piston and liner life 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 Applications Mobil Pegasus 801 is intended 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 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 oils show excellent results in multipurpose natural gas engine 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...
