This bulletin is being revised to add model years and Parts Information. Please discard Corporate Bulletin Number 04-06-04-051B (Section 06 -

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.
