This build-up can cause blockages, leading to lost acceleration, rough idling, and hesitation. The cleaner is designed to be used every 3,000 miles and can be purchased online or at select stores.

The cleaner can be injected into the PCV hose in the intake manifold
The PCV hose in the intake manifold is a super-easy way to clean your fuel system. It is accessible without having to disassemble air ducts, hoses, and other components, which is often the case with the intake manifold.
To begin the cleaning process, you will need to remove the tube off the throttle body and spray the cleaner into the throttle body. This is done to prevent the cleaner from accumulating in the hose curves. You can then proceed to spray the cleaner into the PCV hose. It is important to note that a vacuum hose will likely distribute the cleaner unevenly to the valves. Therefore, it is recommended to spray as close to the intake manifold as possible.
When spraying the cleaner, be sure to spray as heavily as possible without causing the engine to stall. You can do this by giving throttle with the throttle linkage. Towards the end of the can, you can give it a full spray until the engine stalls. It is then advisable to let the cleaner soak overnight. After the cleaning process, it is common for the engine to produce a significant amount of smoke for an extended period, so be prepared for this.
Finally, it is recommended to perform an oil change to remove any residual cleaner from the oil.

Valvoline also offers a full fuel system service and cleaning
Valvoline offers a full fuel system service and cleaning, which is recommended every 15,000 miles. This service includes cleaning the valves and injectors, which can become caked with deposits, dirt, and sludge over time, leading to blockages and reduced fuel mileage and performance.
The process involves injecting an entire bottle of cleaner directly into the throttle body intake, along with a 12-month fuel treatment added to the gas tank. This treatment costs around $20, while the full fuel system cleaning service is priced at approximately $130.
Some Valvoline employees have expressed that the full fuel system cleaning service is not necessary and may not be worth the money. They suggest that the 12-month fuel treatment is sufficient for maintaining fuel injectors.
Additionally, there are alternative methods for cleaning the fuel system, such as purchasing a bottle of fuel system cleaner from an auto store and adding it to the tank during the next fill-up. This option is significantly more affordable, typically costing between $10 and $30.
It is important to note that the effectiveness of these alternative methods may vary, and seeking professional services can ensure a thorough cleaning. Valvoline's certified technicians undergo extensive training to provide reliable fuel system cleaning and injection services.

Fuel additives at some gas stations can help keep injectors clean
Fuel injectors can become clogged with deposits, dirt, and sludge over time, leading to lost acceleration, rough idling, and hesitation. To prevent this, some gas stations offer fuel additives that help keep injectors clean. These additives are designed to be added directly to the fuel tank, and they can provide a number of benefits, including increased fuel economy, reduced emissions, and improved engine performance.
While the effectiveness of fuel additives has been debated, with some motorists questioning whether they deliver on their promises, it is generally agreed that they can be beneficial if used consistently and over a prolonged period. It is also important to use fuel injector cleaners with the correct concentration of cleaning agents to achieve immediate results.
AMSOIL P.i.® Performance Improver, for example, is a potent fuel injector cleaner that has been shown to work after just one tank of fuel. It contains concentrated detergents that aggressively clean deposits, valves, and combustion chambers, resulting in reduced emissions and increased fuel economy of up to 5.7%.
Some gas stations may offer similar fuel additives with their fuel, providing an easy and convenient way to maintain the cleanliness of fuel injectors. However, it is worth noting that not all gas stations provide this service, and it may be necessary to purchase a separate fuel injector cleaner from an auto parts store or a Valvoline shop and add it to the fuel tank during the next fill-up.
