Why do you want to all of a sudden throw in some fuel injector
cleaner? Gasolines are complex products that include several
additives including an injector cleaner. If your car is running rough
it would be much better to find out the reason why and fix the cause.

Most of these bottled automotive elixirs can be said to do no harm,
but that's about it.
