Mobil SHC Pegasus

SHCPegasusMobil SHC Pegasus™

One of the world’s first gas engine oils with energy efficiency benefits

Discover Mobil SHC Pegasus, developed for optimum natural gas engine protection and capable of increasing fuel efficiency up to 1.5%,* while helping to reduce CO2 emissions.

Advanced-technology Mobil SHC Pegasus is designed to maximize natural gas engine component reliability, helping you stay more profitable. With energy costs such a significant percentage of your operating budget — and engine reliability so critical to your productivity and efficiency — Mobil SHC Pegasus is a win/win for your bottom line.
*The fuel efficiency of Mobil SHC Pegasus relates solely to the fluid performance when compared with ExxonMobil’s standard SAE 40 natural gas engine oils. The technology used allows up to a 1.5% increase in fuel efficiency compared with 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.

Features & Potential Benefits

• Patented technology proven to provide up to 1.5% reduction in fuel consumption compared to standard natural gas engine oils*
• 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
• 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 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
• Helps control wear on critical engine components
• Maintains engine reliability and performance
