SPRING, Texas–(BUSINESS WIRE)–ExxonMobil
today announced that Mobil
Jet^TM Oil 387, a synthetic High Performance Capability
(HPC) turbine engine oil, is now approved for use in GP7200 engines.

Developed by Engine Alliance, a joint venture between GE Aviation and
Pratt & Whitney, GP7200 engines represent one of the two
engine technologies approved for use on the Airbus A380, the world’s
largest passenger airliner. With this latest milestone, Mobil Jet Oil
387 is now fully approved for use in all propulsion engines and engine
accessories used onboard Airbus A380 aircraft in operation around the
world.

“We are now one step closer to achieving our goal of securing Mobil Jet
Oil 387 approvals from all manufacturers that produce engine
technologies for wide-body aircraft,” said Vipin Rana, global aviation
lubricants sales manager at ExxonMobil. “This growing number of
manufacturer approvals is leading to more airlines expressing interest
in Mobil Jet Oil 387 as a lubricant solution for their diverse fleets.

”With its balanced formulation and robust anti-oxidant package, Mobil
Jet Oil 387 is well suited for GP7200 engine models. Results from
various testing showed how even under extreme operating conditions and
prolonged oil drain intervals, Mobil Jet Oil 387 can deliver outstanding
engine cleanliness and oxidative stability, and exceptional seal
protection.*

According to Rana, this approval is another clear example of how
ExxonMobil formulators created Mobil Jet Oil 387 to deliver a
combination of performance and benefits never previously achieved with
an HTS/HPC turbine oil.

Since its commercial introduction in late 2012, Mobil Jet Oil 387 has
accrued more than one million hours of on-wing performance. Today, it is
used to protect more than 250 aircraft owned or leased by premium
operators around the world.

Mobil Jet Oil 387 meets demanding industry specifications, including SAE
AS5780 High Performance Capability and U.S. Military Specification
MIL-PRF-23699-HTS. It is approved for use by engine manufacturers in a
wide range of models and components.

All Mobil Jet-branded oils, including Mobil Jet Oil 387, Mobil
Jet^TM Oil II and Mobil
Jet^TM Oil 254, are approved for use in GP7200 engine
models.

Mobil Jet turbine lubricants are produced at ExxonMobil’s
state-of-the-art Port Allen aviation lubricants plant outside Baton
Rouge, LA. The 90,000 square foot facility, which commenced operations
in 2016, features advanced equipment and technologies that
enable ExxonMobil to produce a reliable supply of Mobil Jet oils
and meet the increasing demand for high-performance synthetic aviation
lubricants.
