What You'll Learn
Using fuel additives
There are a variety of fuel additives available on the market, and it is important to choose one that is compatible with your Hyundai Veloster. Hyundai offers its own fuel system cleaner, the "Hyundai Fuel System Cleaner Plus," which is recommended for use during routine service and preventative maintenance. It is designed to clean fuel injectors, intake valves, and combustion chambers, and protect fuel system components from corrosion and damage caused by sulfur content in the fuel. It is important to follow the instructions provided by the manufacturer when using this or any other fuel additive.
Some other popular fuel additives include Techron, which is often recommended for use every 3,000 to 5,000 miles, and Chevron Concentrate Fuel System Cleaner. It is important to note that the Chevron Fuel Injector Cleaner is not recommended for this purpose, as it is a different product. Other options include Gumout Multi-System Tune-Up, which is a blend of Seafoam and Techron, and Redline SI-1, which is recommended for use once a year.
When using fuel additives, simply pour the contents of the bottle into your fuel tank. This process should be done when the tank is nearly empty, and then fill it with fuel as you normally would. It is important to consult your owner's manual for specific recommendations and intervals for adding fuel additives. Some manuals recommend the use of fuel additives at every 7,500-mile interval or when TOP TIER Detergent Gasoline is not available.
In addition to using fuel additives, it is recommended to let your engine fully warm up and give it some revs. This can help clear out any remaining deposits and improve the overall performance of your Hyundai Veloster.

Injector cleaner
A clogged injector can lead to abnormal engine performance, including unstable idle speed and excessive dark smoke emissions. Regular cleaning with an injector cleaner will help you avoid these issues and ensure optimal engine performance. Injector cleaners are chemical formulas designed to break down any deposit build-up in the injectors. They are typically poured directly into the fuel tank, and you can drive your car as usual, allowing the cleaner to work its way through the fuel system.
There are a variety of injector cleaners available on the market, with prices ranging from under $7 to around €15. Some popular options include Chevron Techron, 505 CRF, Seafoam, and Lucas. These cleaners are designed to be used regularly, with some recommending use every 3,000 miles, while others suggest every 5,000 kilometres. It's important to follow the instructions on the bottle for the best results.
For more severe cases of injector clogging, a more complex and expensive technique, such as ultrasonic cleaning, may be required. This method uses ultrasound to dissolve dirt accumulated on the injectors, and it can be done by a specialist or with the purchase of adapted equipment.
By using injector cleaners and maintaining your fuel injectors, you can help extend the life of your engine, improve its performance, and avoid costly repairs down the line.

Cleaning the fuel rail
The fuel rail is an important component of your Hyundai Veloster's fuel system, and it requires regular cleaning to ensure optimal performance. Here's a step-by-step guide on how to clean the fuel rail of your Hyundai Veloster:
Step 1: Understand the Fuel Injectors
Before cleaning the fuel rail, it's important to know the function and operation of the fuel injectors. The injectors play a crucial role in regulating fuel flow into the engine. They are small nozzles that, under pressure, control the release of fuel in the form of micro-drops, improving combustion efficiency.
Step 2: Signs Indicating the Need for Cleaning
There are several signs that indicate it's time to clean your Hyundai Veloster's fuel rail and injectors. These include unstable idle speed, excessive dark smoke emissions, and poor engine performance. Clogged or blocked injectors can lead to bad combustion and, if left unattended, may cause irreversible damage, resulting in costly replacements.
Step 3: Choose a Cleaning Method
There are several methods to clean the fuel rail and injectors. The first method is to use a fuel injector cleaner additive, which can be purchased at most auto parts stores. Simply pour the contents of the bottle into your fuel tank and follow the recommended guidelines. This method is simple and effective in maintaining the injectors if done regularly, but it may not be as effective if the injectors are already heavily clogged.
Another method is to use ultrasonic cleaning. This technique utilizes ultrasound technology to dissolve any dirt and buildup on the injectors. You can either purchase the equipment and perform the cleaning yourself, or you can take your injectors to a specialist who will have more advanced equipment. This method is more expensive but highly effective.
Step 4: Cleaning Process
When using the additive method, refer to the specific instructions on the bottle for the recommended dosage and frequency. Typically, you would add the additive to a partial tank of gas and then drive your vehicle as usual until the tank is almost empty.
For ultrasonic cleaning, if you opt to do it yourself, follow the instructions provided with the equipment. If you engage a specialist, they will guide you through the process and may require you to disassemble the injectors beforehand.
Step 5: Post-Cleaning Verification
After cleaning the fuel rail and injectors, it's important to verify the results. Start the engine and observe if the previous issues, such as unstable idle speed or excessive smoke, have been resolved. You should also notice improved throttle response, power, and acceleration.
By following these steps and performing regular maintenance on your Hyundai Veloster's fuel rail and injectors, you can help ensure optimal fuel system performance and keep your vehicle running smoothly.

Cleaning the throttle body
To clean the throttle body, you will need to purchase a can of throttle body cleaner spray. Before beginning the cleaning process, ensure that your engine is turned off and has cooled down. Here are the steps to follow:
- Remove the intake hose: Start by taking off the intake hose that connects to the throttle body. This will give you access to the throttle plate.
- Open the throttle plate: Manually open the throttle plate by hand. This will expose the area that needs to be cleaned.
- Spray the cleaner: Aim the nozzle of the throttle body cleaner spray into the throttle plate and apply a generous amount of the product. Ensure that you follow the instructions on the cleaner spray can for optimal results.
- Wipe with a rag: After spraying, use a clean rag or a soft cloth to wipe away any remaining residue or buildup. This will help remove any stubborn deposits and ensure a thorough cleaning.
It is important to note that some Hyundai Veloster models may have wires and a radiator hose blocking access to the throttle body. In such cases, you may need to remove additional components, such as the airbox or the boost pipe, to gain better access for spraying the cleaner.
