What is Fuel Injector Cleaner?

Fuel injectors are an important part of a new vehicles operation. In older model vehicles, carburetors were used to mix fuel and air to allow for the fuel to combust.

In modern vehicles, the carburetors are replaced with Fuel Injectors. Fuel Injectors are similar to old-school carburetors, but they are electronically controlled. The electronic control allows for a much more precise mixture of fuel and air to be injected into the engine – allowing better performance, fuel economy, and reduced emissions.

How do Fuel Injectors get dirty?

Over time, a fuel injector can become dirty from continuous operation.

Fuel injectors can become clogged over time with debris from the fuel system. Even though engines have fuel filters, and modern gasoline is high-quality, debris can build up in the fuel system over time, and make it past the fuel filter to clog up the injectors. =

Additionally, fuel injectors can become corroded. In colder climates, it is not uncommon for condensation to build up in a fuel system, which can lead to corrosion over time.

Furthermore, over the regular operation of a vehicle, carbon deposits can build up in your fuel injectors.
