When you start up your car, you'll see the gas gauge slowly settling up in place. Of course, this is if your gas gauge actually works. If not, then go to an electrician to fix it up. This is also a very important step since different fuel injector cleaner require a different amount of gasoline.

Always make sure that you have a required amount of fuel, as this is very important for the efficiency of the injector cleaner.
