    GM recommends Chevron Techron Fuel Injector Cleaner, which has the added benefit of reducing sulphur deposits on the fuel sender units that signal fuel tank levels.

    I second the Techron and suggest you use Shell Premium fuel. It is supposed to have the highest amount of detergents in the industry. My 2005 had the dreaded fuel sender issue that CC mentioned and the combination of Techron and Shell Premium actually reversed the problem without having to drop the tanks and replace the fuel pump assembly. I am a believer.
