The Lubrizol Corporation Unveils Upgraded Automatic Transmission Fluid (ATF) Technology to Satisfy DEXRON®-III, H

CLEVELAND, OH, March 31, 2005 - To better meet the challenges of today's more stringent driving conditions, The Lubrizol Corporation (NYSE: LZ) recently introduced its new DEXRON®-III, H-revised automatic transmission fluid (ATF) additive technology. All products in the new family, when combined with the recommended Group II or III base oil and other components, offer improved oxidation stability, sludge resistance, friction and shifting performance, as well as better usable fluid life and seal compatibility.

The upgrade responds to a variety of trends and market drivers - including higher operating temperatures, reduced sump sizes, higher fluid turnover rates, increased energy densities, reduced cooling capacity and more aggressive electronically controlled capacity clutches (ECCC) usage - all of which are increasingly stressing ATF and led to the GM-issued service-fill specification that called for a conversion of formulations beyond the performance parameters of the former DEXRON®-III, G. The advancement is a culmination of extensive investments by Lubrizol in R&D and testing.

"Many service fluids currently on the market simply do not provide the level of performance that is now required," said Mark Wilson, ATF Additives Business Manager, North America, The Lubrizol Corporation. "This new technology ensures that ATF will better protect transmissions and stand up to modern-day hotter, more demanding operating environments. To accommodate geographical variances, we have more than one product and can help customers match up different base oil use with the proper additive package type and treat rate. In other words, our broad family of products allows customers to tailor their formulations to meet performance characteristics that are a priority in each given market."

The new specification required Lubrizol's DEXRON-III, H-revised technology to pass an extended flat plate friction test (from 100 to 150 hours), transmission oxidation test (from 300 to 450 hours) and cycling test (from 20,000 to 32,000 cycles, or 355 hours).

The new DEXRON-III, H-revised products in Lubrizol's 9600 Series of ATF additive technology addresses a wide range of vehicle applications, from buses to trucks to SUVs and passenger cars. Overall, high-performance ATF technology also works to enhance transmission efficiency, so as to promote better fuel economy and reduced emissions as potential by-products.

The Lubrizol Corporation's automatic transmission fluid (ATF) additive business has more than 76 years as a global industry technology pacesetter, with proven experience in the passenger car, commercial vehicle and off-highway markets. Lubrizol ATF additive chemistry both enables and accommodates the continual evolution of transmission design, allowing lubricant manufacturer customers to meet ever-changing ATF performance demands. The performance needs include better fuel economy, friction performance, CO2 emission reductions, fill-for-life warranty requirements and increased uptime, addressed through fluid durability. Fluid durability and air emissions also work to meet increasingly stringent environmental regulations. With employees strategically located around the world, Lubrizol is able to provide unparalleled and timely product development, marketing and sales support, global manufacturing and distribution.
