Best Fuel Injector Cleaners For 2023

Chevron Techron Concentrate Plus has a lot going for it: A well-known brand name, wide distribution (available online, in auto parts stores, department stores, grocery stores and most Chevron gas stations) and a low price.  And they sell a lot of it (it’s Amazon’s best-seller among fuel injector cleaners). Like Red Line SI-1, Chevron Techron Concentrate Plus is a total fuel system cleaner, going beyond just injectors. And like Red Line, it claims its own exclusive formula, Techron, an additive Chevron has used in its gasoline for decades, in addition to the detergent PEA. Where it differs from Red Line is that it’s for gasoline engines only (Chevron sells a separate fuel injector cleaner specifically formulated for diesels).
