Fuel injectors are an essential component of a vehicle's fuel system, ensuring the optimal combustion of fuel and air to power the engine. Over time, carbon deposits, dirt, and debris can accumulate in the injectors, leading to reduced engine performance, rough idling, and acceleration issues. To address this, fuel injector cleaning services are available at auto service centres like Jiffy Lube, Firestone Complete Auto Care, and Valvoline. These services involve using specialised cleaning solutions and equipment to remove built-up deposits and debris from the injectors, improving engine performance and fuel efficiency.

What You'll Learn
Fuel injector cleaning cost
The cost of fuel injector cleaning varies depending on the method used and the service provider. Some shops may charge around $100 for the service, while others may bundle it with other unnecessary services, resulting in a higher price range of $150 to $200, or even up to $300 when combined with a throttle body cleanout. However, it is important to note that fuel injector cleaning is not a routine maintenance item for most vehicles, and it is often not listed in the owner's manual. Unless your vehicle is experiencing problems or the manual specifically recommends fuel injector cleaning, it may not be necessary to spend money on this service.
One alternative to professional fuel injector cleaning is to purchase a fuel injector cleaner additive, which can be poured directly into the gas tank. These additives can be purchased from auto parts stores or online retailers for under $20. While this method may not be as effective as a professional cleaning, it can help improve engine performance and fuel mileage by removing carbon deposits and debris from the fuel system.
Another option is to use a pressurized canister and a high-powered cleaner to flush the fuel injectors. This method involves attaching the canister to the fuel line and running the engine with the cleaner instead of fuel. The cost of the necessary equipment may vary, but the process can be completed for under $100. However, it is important to note that working on fuel delivery systems can be risky due to high pressure, fire hazards, and contamination risks. Therefore, inexperienced vehicle owners should avoid performing this procedure themselves.
Additionally, some vehicle manufacturers, such as Honda and GM, offer in-tank "Fuel System Cleaning" services before resorting to injector flushing. These services may be available at dealerships or authorized service centers, and the cost may vary depending on the make and model of the vehicle. It is always recommended to refer to the vehicle's owner's manual and seek advice from trusted mechanics or dealerships before proceeding with any maintenance or repair work.

Gas additive injector cleaner
Fuel injectors can become clogged with carbon deposits, leading to a rough idle, lack of power, and hesitation when accelerating. While some shops recommend routine fuel injector cleaning services, this is not always necessary unless a diagnostic has been performed and clogged injectors are the root cause of the problem.
A more cost-effective solution is to use a gas additive injector cleaner, which can be purchased and poured directly into the gas tank. These products are designed to dissolve power-robbing gum and varnish and remove combustion chamber deposits to restore engine performance and fuel mileage.
There are several gas additive injector cleaners on the market, including:
- Chevron Techron
- Gummout Fuel System Cleaner
- Red Line Fuel System Cleaner
- Amsoil PI
- BG's Gas Additive
- STP Pro Aerosol
- Shell Gasoline and Motor Oil
- Hot Shot's Secret Gasoline Extreme
When choosing a gas additive injector cleaner, it is important to consider the ingredients and their concentrations. Polyetheramine (PEA) is a key active ingredient in many of these products, known for its ability to clean the combustion chamber. However, cheaper alternatives may use Mannich detergents, which are less effective in cleaning the combustion chamber but can still provide a solid dose of additive for cleaning intake valves and injectors.
By selecting a suitable gas additive injector cleaner and using it periodically, you can help maintain optimal engine performance and fuel efficiency without incurring the cost of frequent professional cleaning services.

Fuel injector cleaning procedure
Clogged or dirty fuel injectors can affect a vehicle's performance, causing issues such as stalling, misfiring, or even preventing the engine from starting. To clean fuel injectors, you can either take your vehicle to a professional service or perform the cleaning yourself. Here is a step-by-step guide on how to clean fuel injectors:
Step 1: Identify the Need for Cleaning
Before initiating the cleaning process, it is essential to determine whether the fuel injectors require cleaning. Signs of clogged or dirty fuel injectors include a stalling or misfiring engine, decreased engine performance, rough idling, lack of power, or hesitation during acceleration.
Step 2: Prepare the Vehicle
Park the vehicle on a level surface and ensure that the engine is cold before beginning the cleaning process. Locate the fuel injectors in the inlet manifold and disconnect the pipe work. Refer to your vehicle's service manual or an aftermarket maintenance manual for detailed instructions specific to your vehicle's engine.
Step 3: Remove the Fuel Injectors
Disconnect the fuel supply and remove the fuel rails, if necessary. Carefully take out the fuel injectors from the engine, being mindful of any variations in the disassembly process based on the unique characteristics of your engine.
Step 4: Clean the Fuel Injectors
Attach a rubber hose to the opening of the fuel injectors using hose clamps to prevent any spillage during cleaning. Connect one side of an electrical lead to the injectors and the other side to the positive terminal of the vehicle's battery. Once you are ready, connect the lead to create a spark. Allow the cleaner to flow through the injectors to remove any deposits or buildup.
Step 5: Reassemble the Components
After cleaning, reassemble the components by replacing the o-rings, reattaching the fuel rails, and reconnecting the fuel supply. Ensure that all connections are secure and properly tightened.
Professional Services
If you prefer to have your fuel injectors professionally cleaned, several reputable companies offer this service, including Firestone Complete Auto Care, Jiffy Lube, and Delphi Technologies. These companies have experienced technicians who can perform comprehensive fuel system cleaning and maintenance to ensure optimal engine performance.

Fuel injector cleaning frequency
Fuel injector cleaning is an important aspect of vehicle maintenance. While there is no one-size-fits-all answer to the frequency of fuel injector cleaning, as it depends on various factors such as the vehicle's age, mileage, and manufacturer recommendations, there are some general guidelines to consider.
Firstly, it is recommended to refer to your vehicle's owner's manual, as it provides specific guidance on fuel injector cleaning intervals. Some manufacturers might suggest an annual fuel system cleaning, while others may recommend it at certain mileage intervals, typically around every 30,000 miles. Following these recommendations can help prevent clogged fuel injectors and maintain optimal engine performance.
Secondly, the frequency of fuel injector cleaning can depend on the vehicle's age and mileage. Older vehicles with higher mileage tend to benefit more from regular fuel injector cleaning. For example, a high-mileage vehicle may experience improved performance and mileage after a thorough injector cleaning. Additionally, certain symptoms may indicate the need for fuel injector cleaning. These symptoms include rough idling, lack of power, engine misfiring, reduced fuel economy, and hard starting. If you notice any of these issues, it may be a sign to have your fuel injectors cleaned or inspected.
It is worth noting that not all fuel systems require routine injector cleaning. Some vehicles may go longer without experiencing clogged injectors, especially if they are well-maintained. In such cases, a fuel injector cleaning can be considered a preventative measure rather than a routine service.
To summarize, the frequency of fuel injector cleaning depends on a combination of factors, including manufacturer recommendations, vehicle age, mileage, and the presence of any performance issues. By staying vigilant and consulting reliable sources, such as your owner's manual and trusted mechanics, you can make informed decisions about the appropriate cleaning intervals for your vehicle's fuel injectors.
