I tend to not use the fuel system cleaners. You can't possibly know whether your fuel system needs any sort of cleaning without getting it diagnosed. And the aftermarket fuel system cleaner advertisers sure want you to use their product regularly to keep your fuel system clean.
However, a bottle of cleaner isn't a very expensive gamble if you seem to have a problem with the vehicle.
Consumer Reports has said, in their reviews of different brands of gasolines, that if you use a decent brand name of gasoline that has good detergent additives (I recall them mentioning Chevron as well as Amoco, Texaco, Shell and one or two others), then aftermarket fuel system cleaners are usually not worth the money.
