I am concerned because I don't want this to happen to my new '06 as well. I already know about the C5 problems and how Techron or BG44 can help.
Thanks,

I have had this problem and the solution for me is to stop fueling once the gas pump automatically turns itself off. Refrain from putting in any extra fuel...don't add a bit more...stop. It works for me. This will probably get to be a problem in the future, but for now it is controlable if you are just careful in adding fuel. I too have a reluctance to have my car dismantled unless it is absolutely necessary.

GM has a NEW fuel additive part# 88861011 that cleans the sulfur corrosion from the fuel gage sending unit. i never had any of my C-5s fixed as i found out that stop filling when the pump shut off and only used certain brands of gas fixed the problem for me. the C-6 the same thing and no problems
