Texaco, Inc. ("The Texas Company") is the name of an American oil retail brand. Its flagship product is its fuel "Texaco with Techron". It also owns the Havoline motor oil brand. Texaco was an independent company until its refining operations merged into Chevron Corporation in 2001, at which time most of its station franchises were divested to the Shell Oil Company. It began as the Texas Fuel Company, founded in 1901 in Beaumont, Texas, by Joseph S. Cullinan, Thomas J. Donoghue, Walter Benona Sharp, and Arnold Schlaet upon the discovery of oil at Spindletop.

For many years, Texaco was the only company selling gasoline under the same brand name in all 50 US states, as well as Canada, making it the most truly national brand among its competitors. It was also one of the Seven Sisters that dominated the global petroleum industry from the mid-1940s to the 1970s. Its current logo features a white star in a red circle (a reference to the lone star of Texas), leading to the long-running advertising jingles "You can trust your car to the man who wears the star" and "Star of the American Road."[citation needed] The company was headquartered in Harrison, New York, near White Plains, prior to the merger with Chevron.

Texaco gasoline comes with Techron, an additive developed by Chevron, as of 2005, replacing the previous CleanSystem3. The Texaco brand is strong in the U.S., Latin America and West Africa. It has a presence in Europe as well; for example, it is a well-known retail brand in the UK, with around 1,100 Texaco-branded service stations.[
