Engine/Propulsion System).
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 or 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.
