There are many different types of fuel system cleaners. Some are made to clean only the fuel injectors. While these types may work well on the nozzles, they fail to pick up deposits and buildup in the rest of the system.

This can still make it hard for gas to get through the line and cause problems. Unless you know for sure that the only blockage is in the injectors, it’s better to choose an additive that can clean more than one part of the system.  Look for products that are 3-in-1 or even 5-in-1, for the best results. Some can even be added to your engine with oil to help clean out deposits and gum there as well.

Be aware that there are also different types of additives for different fuel types. Some work for gasoline engines, some work better for diesel engines, some are for ethanol blends, and some are made for bio-fuels. Adding the wrong type of injector to the wrong type of fuel could cause a severe problem for your vehicle so be sure to choose the right product for your fuel type.
