Business Editors/Automotive Writers

SAN RAMON, Calif.--(BUSINESS WIRE)--March 18, 2004

ChevronTexaco Global Lubricants, a leading provider of industrial lubricants and reliability solutions, today introduced a new turbine oil formulated to properly lubricate and protect against the harsh conditions found in turbines and gearboxes. The new product, which will be marketed as both Chevron GST 2300 and Texaco Regal Premium EP, is a premium performance turbine lubricant designed for gas, steam and combined cycle turbines, with or without loaded gearboxes. The product's performance characteristics allow it to maintain consistent viscosity, effective sludge control and eliminate the need for separate turbine and gearbox oils.

"In field trials, turbines running our new oil ran twice as long as those using a conventional lubricant," said Katherine Johnson, Industrial Specialist, ChevronTexaco Global Lubricants. "The product exceeds all critical OEM specifications for gas, steam, and highly-loaded gear turbines. It also has an RBOT value of 2300 minutes. No other non-synthetic turbine oil available today can make that claim. When you combine our new turbine oil with ChevronTexaco Global Lubricant's line of industrial heat transfer fluids, coolants and solutions, you create a complete offering for the power generation market that few, if any, can match."

Chevron GST 2300 and Texaco Regal Premium EP Benefits:

Benefits of Chevron GST 2300 and Texaco Regal Premium ED include the excellent water separability characteristics, which allow the oil to maintain a high film strength coating on critical wear points of bearings and gear reducers and assure rapid removal of water contamination. The corrosion inhibition feature protects turbine shafts, gears and lubrication system parts from corrosion and rusting and the foam inhibition element prevents sump overflow.

Additional product benefits include:

-- Superior oxidation stability for long service at elevated

temperatures

-- Protection from sludge and varnish formation

-- Simplified inventory: One lubricant for gearboxes and turbines

-- High viscosity index assuring minimum viscosity change with

temperature variations

-- Quick air release minimizing the possibility of pump

cavitation in systems with high circulation rates and small

reservoirs

-- Formulated with ISOSYN base stocks

The new turbine oil, available in ISO 32 and 46, can be obtained through ChevronTexaco marketers in North America by May 2004.
