Mobil 1 Teams Up with Porsche in Quest for Transsyberia 2007 Rally Win

Beginning on August 3, 24 Porsche teams driving Porsche Cayenne
sport utility vehicles filled with Mobil 1 viscosity grade OW-40 will
compete in one of the world's toughest automotive rally events.
Covering 7,100 kilometers (4,412 miles) of forests, deserts, mountains
and plains over 14 days, the drivers' spirits, navigational skills and
engines will be tested by a challenging route that will take them from
Moscow to the Mongolian capital of Ulaanbaatar.

"From the initial design of the Porsche Cayenne, Mobil 1 has
collaborated with Porsche engineers on the special lubricant
requirements necessary to meet the challenges of every driving
environment," says Hauke Braack, Strategic Global Alliance Manager,
ExxonMobil Lubricants & Petroleum Specialties Company. "We are proud
to be a part of this exciting, multi-terrain journey and wish all of
the Porsche Cayenne teams well in the competition."

Mobil 1 provides a variety of performance benefits to the Cayenne.
These include fuel economy, excellent oil flow characteristics and
outstanding engine wear protection. Mobil 1 can operate in a
temperature range from -45C(-49F) to +200C (+392F). Mobil 1 0W-40 is
ideally suited for high-performance super-charged and turbo-charged
engines.

Porsche uses Mobil 1 as factory-fill in all its current vehicle
models and also recommends the lubricant for all service fills.

Mobil 1 is original equipment in a number of other
high-performance vehicles. Mobil 1 is the world's leading synthetic
motor oil brand.
