*Techron* is a patented fuel additive developed by the Chevron Corporation<http://en.wikipedia.org/wiki/Chevron_Corporation>, usually consisting of gasoline mixed with 400 ppm of polyetheramine.[1]<http://en.wikipedia.org/wiki/Techron#cite_note-Farmer-0> With the introduction of Techron, Chevron gasolines<http://en.wikipedia.org/wiki/Gasoline> became designated as meeting Top Tier standards<http://en.wikipedia.org/wiki/Top_Tier_Detergent_Gasoline> for fuel cleanliness. Chevron gasolines with Techron were some of the first gasolines to be named as a “Top Tier Detergent Gasoline”.[2]<http://en.wikipedia.org/wiki/Techron#cite_note-Upshaw-1> “Top Tier Detergent Gasoline(s)” are agreed to lead to better performance in engines by BMW, General Motors, Honda, Toyota, Volkswagen, and Audi.[2]<http://en.wikipedia.org/wiki/Techron#cite_note-Upshaw-1>Hyundai, Volvo and Mercedes-Benz have issued factory service bulletins advising the use of concentrated Chevron Techron in repair procedures for vehicles with certain mechanical problems.

Techron is available at Chevron, Texaco, and Caltex stations in all three grades of gasoline.[3]<http://en.wikipedia.org/wiki/Techron#cite_note-Techron-2> Techron is also available as a packaged concentrate, for use with lower quality gasoline ("under-additized").

Chevron makes a variety of claims about the Techron fuel additive product. In one claim Chevron says that their additive boosts fuel economy. Another claim Chevron makes is that “Chevron with Techron helps prevent the grimy deposits that degrade an engine’s cleanliness”.[4]<http://en.wikipedia.org/wiki/Techron#cite_note-Chevron-3> Techron is said to protect the engine’s valves as well as combustion chambers from harmful grimy buildup.[5]<http://en.wikipedia.org/wiki/Techron#cite_note-Texaco-4> Chevron also says that the Three Big Detroit auto makers used their additive to pass the EPA's regulations on emissions.[5]<http://en.wikipedia.org/wiki/Techron#cite_note-Texaco-4> [edit<http://en.wikipedia.org/w/index.php?title=Techron&action=edit&section=1> ]
