I own a 2012 Chevy Cruze, and have been having trouble with the fuel gauge sending unit. Chevrolet has a TSB out which references a problem caused by "sulfur deposits" from certain types of gasoline, and they recommend a fuel tank additive (sold through the parts desk) as a possible solution. Their additive seems to be overly expensive, and although I have only used one bottle so far, I have noticed no improvement. Is this a "real" previously-identified issue or am I being snowed? If it's real, is there a Berryman product that might help me? I definitely would like to avoid having to replace the sender/pump unit since their position is that if this is actually caused by "bad gas", it's not covered by warranty.

If the additive that Chevy recommends has a high concentration of polyether amine, then it is possible that it might clean up sulfur deposits. However, we use different chemistries which have not been tested in such applications.
An alternative concept would be using a strong solvent-based product like B-12 Chemtool Fuel Treatment (part #0116) or, better yet, B-12 Chemtool Total Fuel System Clean-Up (part #2616). If you took this approach, it would be most effective to use the fuel additive while as low on gas as possible and then giving the product as much time to solvate the sulfur deposits as possible. Doing so on a warm day would help, too. Good luck!
