simple question, bought some carb and fuel injection cleaner several years back and kept it put away in the garage till needed , well it was forgotten but unopened so was wondering.....does something like fuel injector and carb cleaner have a "shelf life" that can become ineffective or even harm my fuel already in the tank ?? its the bottled kind poured in with a fillup
