Techron® Concentrate Plus is a premium fuel additive that deep cleans your gasoline fuel system in one tankful. Using Precision Clean TM technology, this fuel additive works at molecular levels to soften the deposits found in critical parts of the car’s engine system and suspend them in fuel. These deposits are then carried through to the combustion chamber to be burnt and ejected in the exhaust. With more than 30 years of research and development, one little bottle of this advanced fuel additive can help restore and maintain your engine performance.
