Mobil SHC Pegasus™ 40
Synthetic Gas Engine Oil
Mobil SHC Pegasus™ 40 is a new category of advanced technology natural gas engine oil designed to provide today's high output, low-emission four-cycle gas engines with the highest levels of protection. Mobil SHC Pegasus 40 uses a patented combination of high quality base stocks and advanced additive technology to deliver exceptional oxidation stability, nitration resistance and thermal stability. Its formulation has been carefully balanced to provide outstanding anti-wear characteristics and to control the formation of carbon and varnish deposits.
Features and Benefits
• Outstanding anti-wear characteristics help to protect heavily loaded valve train components, pistons, liners, bearings, and gear trains
• Excellent detergent-dispersant system controls the formation of carbon and varnish deposits to minimize oil consumption and maintain engine cleanliness even during extended drain intervals
• Exceptional oxidation stability, nitration resistance and thermal stability provide the opportunity to extend drain intervals by four to eight times that of conventional gas engine oils
• Low volatility reduces oil consumption and reduces deposit formation
Applications
• 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 fuelled engines equipped with catalytic converters
• Gas engines operating on fuel that contains low levels of H2S
