Techron is a patented fuel additive developed by the Chevron Corporation, usually consisting of gasoline mixed with 400 ppm of polyetheramine.〔Farmer, Robert F., Fuel Compositions Containing Estermines〕 With the introduction of Techron, Chevron gasolines became designated as meeting Top Tier standards for fuel cleanliness. Chevron gasolines with Techron were some of the first gasolines to be named as a “Top Tier Detergent Gasoline”.〔Upshaw, Lynn B. , Truth: new rules for marketing in a skeptical world, Amacom, 2007, pg. 171〕 “Top Tier Detergent Gasoline(s)” are agreed to lead to better performance in engines by BMW, General Motors, Honda, Toyota, Volkswagen, and Audi.
