Fuel injector cleaning

Should I get fuel injector service?

If your vehicle is running well but the shop recommends a fuel injector cleaning, be aware that most car maker don’t recommend routing fuel injector cleaning. If fact, GM has issued a service bulletin #04-06-04-051D to address the issue of unnecessary routine fuel injector cleaning. Read it for yourselves here

General Motors is aware that some companies are marketing tools, equipment and programs to support fuel injector cleaning as a preventative maintenance procedure. General Motors does not endorse, support or acknowledge the need for fuel injector cleaning as a preventative maintenance procedure.

Fuel injector cleaning is approved only when performed as directed by a published GM driveability DTC diagnostic service procedure. Due to variation in fuel quality in different areas of the country, the only preventative maintenance currently endorsed by GM regarding its gasoline engine fuel systems is the addition of GM Fuel System Treatment PLUS added to a tank of fuel at each oil change.
