Performance profile
Mobil SHC Pegasus™ Advanced synthetic gas engine oil
Key benefits Formulated to potentially help limit fuel consumption Helps maximize engine availability through long drain intervals — more than 50,000 hours documented Promotes engine efficiency and reliability by helping control deposits in combustion chamber and piston ring zone
Mobil SHC Pegasus™ gas engine oil is designed to provide today’s high output, low-emission, four-cycle four -cycle gas engines with the highest levels of protection, along with the potential for fuel consumption reductions. Operators worldwide choose it to help: • Maintain engine performance by helping control wear on critical components • Enhance catalytic converter life by helping minimize engine and exhaust system deposits • Limit maintenance and lubricant costs through long drain intervals
Up to 1.5% increase in fuel efficiency compared to standard natural gas engine oils*
1.5%
Approvals Mobil SHC Pegasus gas engine oil is approved for use in KAMA Z gas engines and General Electric Waukesha APG 100 0 engines. Waukesha cited good results for engine component wear and deposit control as well as fuel efficiency improvement.

The energy efficienc y of Mobil SHC Pegasus ™ relates solely to the fluid perfor mance when compared to ExxonMo bil’s standard SAE 40 natural gas engine oils. The technology used in Mobil SHC Pegasus demonstrated up to a 1.5 percent increase in fuel efficiency, as measured by fuel consumed in operation, compared to Mobil Pegasus ™ 1005 and 805 series when tested in standard natural gas engine applications under controlled conditions. Eff iciency improvements will var y based on operating conditions and applications. The energy ef ficiency claim for this product is based on test results on the use of the fluid conducted in accordance with all applicable industry sta ndards and protocols. *

Long drain intervals In the Mobil™ bulk oil oxidation test (B-10), which indicates oxidative stability, Mobil SHC Pegasus™ oil demonstrates performance superior to conventional oil. This capability equates to longer drain intervals and low churning losses, which could translate to an efficiency benefit.
Deposit control The hot tube test measures an oil’s ability to resist deposit formation under high-temperature conditions. As piston deposits increase, engine efficiency decreases. Mobil SHC Pegasus™ oil demonstrates outstanding performance in this test. 10 9
