Techron, formerly known as techroline, is a patente additive developed by Chevron Products Company, consisting of a family of compounds known as polyether amines. Techron reduces accumulation of deposits in fuel injectors and on intake valves, and prevents or removes sulfur deposits from fuel sending units. With the introduction of Techron, Chevron gasolines became the first fuels designated as meeting TOP TIER standards for fuel cleanliness.
