ExxonMobil Reintroduces Mobil 1 0W-20 Motor Oil; Synthetic Mobil 1 0W-20 Provides Outstanding Protection for Newer Vehicles and Hybrids

FAIRFAX, Va.--March 8, 2006--As consumers continue to place high importance on fuel economy, the demand for hybrid and smaller gasoline-powered vehicles is on the rise. To meet the needs of these more fuel-efficient vehicles, ExxonMobil has reintroduced Mobil 1(R) 0W-20 to its Mobil 1 motor oil line.

Mobil 1 0W-20 is a fully synthetic formula that helps reduce wear and extend engine life while delivering the best fuel economy within the Mobil 1 line. The low viscosity of Mobil 1 0W-20 allows for quick oil flow to protect critical engine parts during the frequent start-ups that occur in gasoline/electric hybrids.

In addition to providing benefits for hybrid engines, Mobil 1 0W-20 is ideal for use in newer cars, trucks and SUVs manufactured by Honda, Toyota, Ford, Mercury and Chrysler, where a 5W-20 motor oil is recommended. Mobil 1 0W-20 not only meets the requirements of manufacturers recommending 5W-20, but it also provides superior low-temperature protection and the exceptional performance of a fully synthetic motor oil.

"Mobil 1 0W-20 is a high-quality oil that fills a growing need for this viscosity," said Brad Onofrio, automotive marketing manager - Americas Region, Exxon Mobil Lubricants & Specialties Company. "The reach of this motor oil is well beyond just hybrid vehicles; it is well-suited to provide fuel-efficiency benefits for many newer vehicles."

With an increasing number of manufacturers recommending 0W-20 and 5W-20 viscosities for many types of newer vehicles, the sales of Mobil 1 0W-20, originally introduced in 2002, are expected to grow significantly.

Mobil 1 0W-20 will be available through leading automotive retailers this month.

Mobil 1 is the world's best selling synthetic motor oil, with the technology to exceed the toughest standards of Japanese, European and U.S. car builders - and to provide exceptional protection against engine wear, under the most demanding conditions.
