ExxonMobil Introduces Next Generation Natural Gas Engine Oil

ExxonMobil today announced that a new addition to its Mobil
Pegasus Series of high-performance lubricants for natural gas engines,
Mobil Pegasus 1005, will be introduced worldwide.

Formulated with the highest quality basestocks and advanced
additive technology, Mobil Pegasus 1005 is designed to provide today's
high output, low-emissions four cycle gas engines with exceptional
levels of protection while also delivering superior performance for
older model engines.

"To stay ahead of the competition in today's global industrial
marketplace, companies need to invest in products that are designed
specifically to help enhance the productivity and durability of their
most critical equipment," said Jeff Biamonte, ExxonMobil's global
industrial advisor. "Mobil Pegasus 1005 was developed through
extensive laboratory and engine bench testing, as well as
comprehensive field tests with major OEMs around the world, to ensure
its exceptional performance capabilities over the long haul."

"This testing showed that Mobil Pegasus 1005 can provide double
the oil life, compared with previous mineral oil based Mobil Pegasus
formulations, thus helping companies reduce their oil consumption, oil
disposal and maintenance costs."

With more than 40,000 hours of rigorous field testing, conducted
with customers and leading OEMs, Mobil Pegasus 1005 provides
outstanding anti-wear characteristics to protect heavily loaded valve
train components while maintaining compatibility with catalytic
converter materials.

"Its advanced detergent-dispersant system controls the formation
of carbon and varnish deposits to minimize oil consumption and
maintain engine cleanliness even during extended drain intervals,"
said Kevin McKenna, ExxonMobil's product technical advisor.
"Minimizing piston deposits and controlling oil consumption are
critical factors that went into the design and development of Mobil
Pegasus 1005."

In addition, Mobil Pegasus 1005 provides exceptional oxidation
stability, nitration resistance and thermal stability, which helps to
maintain the highest level of engine cleanliness and can improve
customer value by enhancing equipment performance and durability.
