Fuel injectors have tight tolerances, meaning even small amounts of carbon buildup can affect your engine’s performance. Fuel additives are a nice addition for preventative car maintenance on your injectors to help delay or prevent an expensive repair later on.
On a simple level, gas treatments work when they are present in the fuel before combustion. The recommendation would be to add any gas treatment you want to use during your fill-up, before you add more gas. Administer the recommended amount of gas treatment into your partially-filled tank, then fill up as normal.
