Chevron Introduces TECHRON Concentrate Plus; Reformulated Version of Trusted TECHRON(R) Concentrate Cleans Engines and Protects Fuel Systems from Harmful Sulfurs

SAN RAMON, Calif.--Nov. 2, 20051, 2005--Chevron Products Company, a leading provider of engine oils, lubricants, coolants and related services, today introduced a new addition to its industry-leading family of fuel additives. TECHRON(R) Concentrate Plus Fuel System Cleaner, a reformulated version of Chevron's TECHRON(R) Concentrate, is the only fuel additive that provides both unbeatable engine deposit control and protection against harmful sulfurs that can cause fuel gauge sensors to malfunction.

Now that used cars comprise roughly 85 percent of automobile sales in the U.S. (U.S. Department of Transportation, 2003), and many gasoline marketers have reduced the concentration level of fuel additive in their gasoline by up to 50% since the EPA set a minimum standard in 1995 (www.toptiergas.com), engine intake systems are increasingly susceptible to the buildup of deposits that can gradually deprive them of their power, performance, drivability and fuel efficiency.

To better combat the buildup of deposits in an engine's intake system, and to remove combustion chamber deposits that naturally accumulate over time regardless of gasoline brand used--both of which can affect vehicles' performance like a slow growing cancer--Chevron TECHRON(R) Concentrate Plus delivers the most advanced engine deposit control technology available today.

With its exclusive synthetic formula, one bottle of TECHRON(R) Concentrate Plus improves engine performance for up to 3,000 miles by cleaning deposits from fuel injectors, carburetors, intake valves, ports and combustion chambers. It can help restore lost power; lower exhaust emissions; reduce engine knock, ping and run-on; and relieve cold start-up problems.

In older vehicles, combustion chamber deposits will sometimes cause engine knock unless the motorist uses a higher octane fuel than specified in the owner's manual. One bottle of TECHRON(R) Concentrate Plus can help decrease the octane requirement of these vehicles, eliminating knock and allowing the motorist to use less expensive lower octane fuels. The protection offered by the product against fuel system sulfur deposits has also been shown to last for thousands of miles.

"One of the most advanced fuel system cleaning tools in today's market, TECHRON(R) Concentrate Plus is an easy and cost-effective way to maintain optimal engine performance and fuel efficiency, especially for used car drivers who need to remove engine deposits neglected by their vehicles' previous owners," said Alison Townley, business manager, Consumer Products Marketing - North America, Chevron Products Company. "With regular use, it can help lower exhaust emissions and maximize performance over the life of the engine."

Available in two bottle sizes, TECHRON(R) Concentrate Plus can be used with most vehicles, including light-duty direct and indirect-injected diesel engines, gasoline-electric hybrid vehicles, direct injection spark ignition (DISI) gasoline engines and all ethanol-oxygenated gasolines. The 20 oz. size treats up to 20 gallons of fuel and is designed for larger cars, light-duty trucks and sport utility vehicles. The 12 oz. size treats up to 12 gallons of fuel and is designed for smaller cars and trucks. The new fuel additive will be available at national retail chains and auto parts stores this December.
