Three Jet Oils from ExxonMobil Aviation Lubricants Now Listed on Qualified Products List for SAE AS5780A Specification

FAIRFAX, Va.--(Business Wire)--ExxonMobil Aviation Lubricants today announced that three of its
jet oils are approved to the new specification for aero and
aero-derived gas turbine engine lubricants endorsed by civil aviation
authorities. Mobil Jet Oil 387 joins Mobil Jet Oil II and Mobil Jet
Oil 254 on the Qualified Products List (QPL) of SAE International, the
world's largest aerospace standards development organization.

Until now, the performance requirements of gas turbine lubricants
had been defined by military and Original Engine Manufacturers (OEM)
specifications. The new specification, called AS5780A, incorporates
input from civil aviation authorities for the first time. It was
developed to meet the growing performance and quality needs that
commercial airlines seek, especially with the entrance of new
higher-output and lower oil-consumption engines.

The standard also includes significant input from engine
manufacturers and major lubricant providers, as well as many
government agencies. These agencies include Canadian, German and
French militaries, UK Defence Fuels Group, QinetiQ and the US Navy and
US Air Force. Support for the standard also came from the French
Direction Generale de l'Aviation Civile (DGAC), UK Civil Aviation
Authority (CAA) and the US Federal Aviation Authority (FAA).

The SAE AS5780A specification defines the basic physical, chemical
and performance limits for five centistoke viscosity grades of gas
turbine engine-lubricating oils used in aero and aero-derived marine
and industrial applications. The specification also describes standard
methods and requirements for laboratories performing the tests to
qualify oils.

Mobil Jet Oil II was approved to the SAE AS5780A specification in
August 2007. The high-performance, aircraft-type gas turbine lubricant
is recommended for aircraft gas turbine engines of the turbo-jet,
turbo-fan, turbo-prop and turbo-shaft (helicopter) types in commercial
and military service.

Mobil Jet Oil 254 is a third-generation, extra high-performance,
synthetic aircraft-type gas turbine lubricant for gas turbine engines
used in commercial and military aircraft that operate in a wide range
of severe conditions. It was also approved to the SAE AS5780A
specification in August 2007. A product with advanced thermal and
oxidation stability, Mobil Jet Oil 254 is recommended for aircraft
turbine engines of the turbo-jet, turbo-fan, turbo-prop and
turbo-shaft (helicopter) types used in commercial and military
service.

Mobil Jet Oil 387 was formulated with the latest technology to
meet the AS5780A High Performance Capability (HPC) standard. It was
approved to the SAE AS5780A specification in November 2007. A product
with advanced deposit control and excellent seal compatibility, it is
suited for aircraft operating with particularly severe equipment or
service requirements. ExxonMobil plans to launch this new product in
the near future.

"As the only supplier with three jet oils meeting the new AS5780A
standard, we have reaffirmed our commitment to providing cutting edge
aviation lubricant technology and remaining a step ahead of our
customers' evolving needs," says Mike Hawkins, global marketing
manager, ExxonMobil Aviation Lubricants.

the Wright Brothers flew with Mobiloil in their airplane's
four-cylinder engine. Today, ExxonMobil Aviation Lubricants is a
leading supplier of jet oils, hydraulic oil, piston oils, greases and
