ExxonMobil Develops Low SPAsh Diesel Engine Oil for DaimlerChrysler's New Diesel Particulate Filter

FAIRFAX, Va.--Oct. 2, 20033, 2003--

Working Together Oil Filter and Engine Oil Meet EU Emission Standards Ahead of 2005 Deadline

ExxonMobil today announced that a cooperative technology project with DaimlerChrysler has resulted in the development of a new low sulphur, phosphorus and ash -- Low SPAsh -- diesel engine oil that, when coupled with DaimlerChrysler's new maintenance free diesel particulate filter (DPF), reduces automotive emissions.

ExxonMobil worked closely with DaimlerChrysler on the development criteria that its new filter required of the engine oil and consequently produced a lubricant with specifications that met the desired requirements.

The innovative technological development of filter and oil meets EU 4 (European Union) automotive emission regulations more than a year before they become effective in 2005, and sets an industry benchmark for the reduction of soot, hydrocarbons and nitrogen-oxide emissions.

DaimlerChrysler's new maintenance free diesel particulate filter was launched in September at the Frankfurt Autoshow. The new filter is currently available as a customer option on Mercedes Benz diesel automobiles in Europe. The new Mobil-branded Low SPAsh oil will be the factory fill in these automobiles and will be commercially available in late 2003 as part of the family of Mobil-branded engine oils.

"We have been working for many years with DaimlerChrysler on automotive developments and it is very rewarding to see these technical innovations reach the market," said Roland J. Frey, marketing director, Strategic Global Alliances, ExxonMobil Lubricants & Specialities. "The results of this joint innovation -- filter and oil working together -- prove that when two organizations are committed to high performance products, advanced technologies and a cleaner environment, they can produce a groundbreaking system."

"We are proud to be at the forefront of a technical development that is ahead of European legislation on emissions," said Leopold Mikulic, vice president, DaimlerChrysler Powertrain Development. "This has only been possible with the strong support from ExxonMobil."
