Mobil SHC Pegasus uses a patented combination of high quality base stocks and advanced additive technology to deliver exceptional oxidation stability, nitration resistance and thermal stability, which in turn provide the opportunity to extend drain intervals by up to three times that of conventional gas engine oils.   The formulation of Mobil SHC Pegasus has been carefully balanced to provide outstanding anti-wear characteristics to protect heavily loaded valve train components, pistons, liners, bearings, and gear trains while maintaining compatibility with catalytic converter materials. Its detergent-dispersant system controls the formation of carbon and varnish deposits to minimize oil consumption and maintain engine cleanliness even during extended drain intervals.  Extended drain intervals can translate to to lower operating and maintenance costs. 

Fuel can be one of the largest expenses in any application.  Mobil SHC Pegasus offers the opportunity to reduce fuel consumption.  Extensive and statistically validated independent laboratory testing, bench testing and field testing demonstrated that Mobil SHC Pegasus helped reduce fuel consumption by up to 1.5% compared to a standard natural gas engine oil.* 

Together with ExxonMobil application and engineering expertise, Mobil SHC Pegasus can help users keep their engines running longer and cleaner with improved reliability, reduced oil consumption, and reduced fuel consumption, helping to increase productivity and reduce environmental foot print.

* - The fuel efficiency of Mobil SHC Pegasus relates solely to the fluid performance when compared to ExxonMobil's standard SAE 40 natural gas engine oils. The technology used in Mobil SHC Pegasus demonstrated up to a 1.5% increase in fuel efficiency compared to Mobil Pegasus 1005 and 805 series when tested in standard natural gas engine applications under controlled conditions. Efficiency improvements will vary based on operating conditions. The energy efficiency claim for this product is based on test results on the use of the fluid conducted in accordance with all applicable industry standards and protocols.

Mobil SHC Pegasus offers the following features and potential benefits:

Features	Advantages and Potential Benefits
Reduced Fuel Consumption	Patented technology proven to provide up to 1.5% reduction in fuel consumption compared to standard natural gas engine oils*
Extended Oil Life	Improves oil drain interval; reduces number of oil changes, fewer oil purchases, creates less waste oil and labor to help lower operating costs and increase engine availability Increased engine availability enables higher productivity
Keep Clean Performance	Helps control deposits in combustion chamber and piston ring zone to maximize engine efficiency and reliability Helps control deposits in heat exchangers to maximize heat production
Low Oil Consumption	Low oil volatility helps minimize engine and exhaust system deposits to help extend catalytic converter life and extend intervals between heat exchanger cleanings Helps reduce make up oil additions and lubricant purchases
High Level of Wear Protection	Helps control wear on critical engine components  Maintains engine reliability and performance

Mobil SHC Pegasus is designed for use in:

• Turbocharged, naturally aspirated, medium to high speed four-cycle engines requiring a low ash oil
• Lean-burn and stoichiometric four-cycle engines operating under high load, high temperature conditions
• High-speed four-cycle gas engines used in cogeneration applications
• Natural gas fueled engines equipped with catalytic converters
• Field gathering operations where sour gas H2S content is ‹ 0.1% (1000 ppm) may be used as fuel
