Unless you are running a very rich fuel mixture from an aftermarket tuner your motor probably will not get much carbon build-up. Most of the high octane fuel such as Shell Gold clean the engine as you drive it. But there are fuel injector cleaners which are fine to use. When I use them I usually go for a long ride to run the injector cleaner through. I feel uneasy about letting it sit for days or weeks in the tank and fuel lines.
