Chevron

Chevron is one of the world's largest integrated energy companies, headquartered in San Ramon, California. In the automotive aftermarket, Chevron is best known for Techron — a polyetheramine (PEA)-based fuel system cleaner that Chevron developed and has sold under that brand name since the 1990s. The Techron detergent additive package is also licensed to other fuel companies and used in several Top Tier-certified gasoline formulations, making it one of the most widely distributed and independently documented detergent chemistries in the fuel additive category.
