It is labeled what I called it. If you go to Walmart and look, it will be obvious which one I'm talking about. I don't think there is any carb cleaner in a bottle that is intended to be added to the gas tank. Carbs have disappeared mostly. They are all injector cleaners. But, Gumout with PEA (polyetheramine) works great for cleaning the carbs as you ride. Lately I've noticed that many other injector cleaners have PEA on the label. Chevron Techron was the first one with PEA I think but they don't have it on the label.
