Our Mobil SHC Pegasus™ Series gas engine oils provide maximum protection for high-output, low-emission four-cycle gas engines while also helping to increase fuel efficiency and reduce CO2 emissions. They are formulated for heavily loaded valve train components, pistons, liners, bearings and gear trains.
Proven to increase efficiency up to 1.5 percent*, these lubricants can also:
- Reduce the formation of carbon and varnish deposits
- Minimize oil consumption
- Maintain engine cleanliness during extended drain intervals
- Lower operating and maintenance costs
-
Formulated to potentially help limit fuel consumption
-
Promotes engine efficiency and reliability by helping control deposits in combustion chamber and piston ring zone
-
Up to 1.5% increase in fuel efficiency compared to standard natural gas engine oils*
-
Helps maximize engine availability through long drain intervals — more than 50,000 hours documented

Product information
Product Description
Mobil SHC Pegasus™ 30 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 30 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.
* Energy efficiency explained
The energy efficiency design is a trademark of Exxon Mobil Corporation. The fuel efficiency of Mobil SHC Pegasus 30 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 30 demonstrated up to a 1.5% increase in fuel efficiency when tested in standard natural gas engine applications under controlled conditions. The energy efficiency claim for this product is based on test performed in accordance with all applicable industry standards and protocols. Efficiency improvements will vary based on operating conditions.
