Yes, the detergents in modern fuels should be able to deal with keeping things clean. The "Top Tier" labeled fuels should be fine tuned to deal with the most challenging injectors, GM's SCPI:

So they should be more than ok for regular PFI injectors. If you're concerned, toss in a bottle of Techron Concentrate Plus at the recommended rate. One ounce of bottle per gallon of fuel tank. Several jobs ago I tested that stuff. It does an excellent job on injectors, intake valves, and combustion chambers.

In conclusion, I think that your fuel injectors probably don’t need to be cleaned unless you have some issue that points to a leaking or clogged injector. Or, you are building a high HP motor and need the injectors to be balanced.
