I am of the understanding that fuel injector cleaners are useless.
Is there any real scientific study data? I could understand if a particular car is driven in a particular manner where there might be some issues with clogged injectors, but I am to understand normal driving keeps them clean.
As long as it doesn't harm anything, I guess it's at worst just a few bucks spent.
