Types of Fuel Injector Cleaners

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.
