Techron is a patented fuel additive developed by the Chevron Corporation, usually consisting of gasoline mixed with 400 ppm of polyetheramine (PEA).[1] 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".[2] "Top Tier Detergent Gasoline(s)" are agreed to lead to better performance in engines by BMW, General Motors, Honda, Toyota, Volkswagen, and Audi.[2]

Techron had been first patented and introduced as a concentrate available at Chevron stations in 1981.[3][4] Techron was then marketed in all Chevron gasolines in May 1995, and the Chevron Cars made their debut to promote this introduction in advertising.

Techron is available at Chevron, Texaco, and Caltex stations in all three grades of gasoline.[5] Techron is also available as a packaged concentrate, for use with gasoline that does not include Techron.


Techron consists of five components:[6]

  1. Distillates, hydrotreated light at 40-70% weight
  2. Stoddard solvent at 15-40% weight
  3. Solvent naphtha (petroleum), light aromatic at 5-10% weight
  4. Benzene, 1,2,4-trimethyl at 1-5% weight
  5. PEA (detergent), polyether amines at 20-49% weight


Techroline was the predecessor to Techron. The company claimed it could control combustion-chamber deposits in cars,[7] as well as keep their fuel-intake systems clean.[8]
