Fuel Induction Service

What is a Fuel Induction Service & Will it Help?

In Engine by 17 Comments

Did your mechanic recommend that you should get a fuel induction service on your car?

What is a fuel induction service, and will it improve the performance of my car? How efficient is it, and is it just a waste of my money?

The fuel induction service is not a very well-known service for most people, and there are a lot of questions about whether it improves the efficiency of your engine or not.

What if you could save your money and do a fuel induction service yourself? Let’s find out in this article!

What is a fuel induction service?

Spray In Cars Intake

A Fuel Induction Service is nothing but a particular type of service and maintenance procedure for your car’s engine.

It’s a process of cleaning the electronic throttle body, air intake valves, and fuel injectors, which you can find in electronically fuel injected vehicles and newer vehicles.

The throttle body and the plate are manually cleaned by the mechanic or technician using a particular throttle cleaning substance.

Here are the benefits of getting the fuel induction service:

  • Improves your car’s gas mileage
  • Smooths your engine’s idle
  • Improves the throttle response

Would I recommend doing a fuel injection service at a mechanic workshop? – Not directly if it is not necessary.

If you have a direct-injected engine that is running rough or has misfires because of leaking intake valves, I would recommend it – otherwise not.

The most parts of the fuel induction service you can do yourself at home with some products. You will find these steps further down in the article.

Why is a fuel induction service performed?

Sooty Valves

A fuel induction service is performed to clean the throttle body, intake valve, intake manifold, and other intake related parts that affect the air-fuel mixture.

When your car gets older, it will start to collect old carbon deposits everywhere on the engine’s intake side. This is caused by carbon entering from the crankcase ventilation and the EGR valve. It can also come from oil slipping through the turbo.

This especially happens on direct-injected fuel engines, which does spray the fuel directly into the combustion chamber. Older engines sprayed the fuel before the intake valves, which cleaned them and did not cause problems like this as often.

These carbon deposits will build on the valve body, intake pipes, intake manifold, and intake valves. This is exactly why a fuel induction is performed to clean these parts from carbon deposits.

This will affect the air-fuel mixture and the intake valves’ seals, which will result in a much smoother engine.

Pros of a fuel induction service

  • Cleans the throttle body
  • Cleans the intake manifold
  • Cleans the intake valves
  • Cleans other flaps inside the intake manifold if fitted

Signs Your Car Needs A Fuel Induction Service

Dirty Throttle Body

You know now what the fuel induction service does for your engine, but the question arises; should you get the service done frequently?

While the fuel induction service does benefit your car, this should not be done regularly and only if you encounter problems individually as a result of carbon building up.

Here are a few signs and symptoms you can look for to determine if you should get a fuel induction service done.

  1. Your car isn’t able to idle smoothly
  2. You feel the vibration as you give gas
  3. You feel a delay in the engine’s pick up as you press on the gas pedal
  4. You experience an extremely low gas mileage
  5. The car doesn’t start as quickly as it used to

Only if you begin to experience these factors should you think about getting a fuel induction service.

What does this service include and how is it performed?

Sooty Combustion Chamber

These are the steps included in a fuel inductor service if a mechanic workshop would do it. As you may see, a lot of parts you can actually do yourself at home.

1. Intake valve cleaning

This step is done by spraying a special liquid into the intake valves while the engine is running. This feeds the engine with throttle cleaner fluid and the air, which gets into the mixture and is ignited. This ensures cleaning the carbon deposits inside the intake and the intake valves.

The compound breaks up the deposits inside, and the remains are let out via the exhaust.

A similar variant of this step can be made by yourself at home with the help of seafoam. This is where you can find seafoam if you are interested:

2. Throttle body cleaning

This is an optional service for a fuel induction, depending on the workshop. Sometimes the throttle body is just cleaned by the injector cleaner entering the engine.

But if a throttle body cleaning is performed, the mechanic or technician would first remove the throttle body from the engine. A particular compound called the throttle cleaner is used to clean the carbon. This is a liquid substance and comes in spray cans.

3. Fuel Injector Cleaning

This is also an additional service that your mechanic sometimes offers when you are doing a fuel induction service. This includes filling a special additive into the fuel tank, which will clean the fuel pump and fuel injectors.

There are special injector cleaner additives that do this job for you, and it is something you can do yourself just by buying one of these. If you want to perform this step by yourself, I can recommend this one from Amazon:

  1. Thank you for explaining this process. I recently purchased a 14 Santa Fe Hyundai, I’ve never owned a Hyundai so I’m not sure of the sounds, feel and quirks of the brand. Over the past 3 months I have noticed some odd things with regards to shivering while at a stoplight or slight delay when I accelerate quickly such as when entering onto the freeway, also the engine idles hard. The dealership suggested fuel induction service at my 1st oil change. At first I thought it sounded bogus and some research leans that way but after reading your article I think it’s possible I could need this service. I’m the 3rd owner of the vehicle and although the previous owner has excellent records I think this could be needed. Thanks again!

      A fuel induction service could absolutely fix your problem. However, in this case, I think it’s smarter to make a proper diagnostics of why the car is running poorly before doing the service. At least read the trouble codes from the engine control unit to see if there are any errors stored.

    2. I have a 2018 Rav4 XLE and the Toyota dealership said that they recommend the fuel induction service done on my next visit… I find that odd on such a new vehicle. I have 23,260 miles on it. Does this sound like a scam?

  2. My 2009 Hyundai Genesis was getting highway mileage 27 mpg. After the dealer talked me jnto induction service that I wasn’t too sure about, the car’s mileage increased to 30.2 mpg on a 1200 mile trip.

    1. That’s because you went on a 1200 mile trip which was likely all highway driving which allows you to have better MPG.

  3. My 2015 Sonata has 96,000 km and is well maintained with regular oil changes and service maintenance. The dealer is now indicating that a Fuel Induction service is required immediately. I have not noticed any stubborn acceleration, idling or any other issues normally associated with the need for this type of service. Could they be recommending this service simply because of the high mileage on the vehicle

  4. Ha!
    The new GM dealership where I had bought my new 2013 Buick Encore is regularly recommending services that are not in the owner’s manual. Fuel/air induction service is the latest of several, many of which I can do myself easily. Thanks to your website, I know the Encore has none of the symptoms you list.
    When the heater stopped working, my husband noticed the overflow container for the coolant was empty and the screw top was only loosely in place, thanks to the same dealership with their multi-point check when the oil was changed. That’s a scary place.
    You’ve saved me from any concern, time, effort, and $. Thank you.

  5. I have 2016 Mazda CX-9 with 45000 miles on it. I have mixed driving-highway and local.
    The service advisor has not only recommended fuel induction service twice so far during last few service trips, but he also said I should have done that service twice by now.
    I asked him, I did not see it in the manufacturer recommended service schedule so why would my car need it? He did not have any satisfactory answer.

    Having said that, I don’t think I need to spend that $150.00 for no reason. Any tips/suggestion from anyone?

    1. Research Sea Foam Pour & Spray Combo Pack. Use this religiously and you’d be better off in the long run especially that you don’t have too many miles. My truck has 135, 000 miles.. However, if your car experiences any of the symptoms that may indicate your injectors need a professional cleaning done, then at that time i would get a fuel injector cleaning.

  6. Is this service needed with a 2015 Ford fusion with approximately 59k on it , and showing no symptoms. There calling me in for routine maintenance.

  7. I have a 2013 Toyota Prius with 165,000 miles and my mileage has really decreased. When I first bought it I was getting 50+ mpg. Now I am getting around 38 mpg. Could this service significantly improve my mileage? I also seem to go through a quart of oil every 800 miles or so.

    1. I have a 2016 VW Passat w 61k miles. Had been experiencing lag in power when trying to accelerate quickly. Hwy mileage dropped to 33-34 mpg from 38-40 mpg. Had induction service today. After driving about 5-7 miles afterwards, car drove and responds as when I first bought it. I did not realize how bad the performance had become. It cost me $240. Typical VW dealer overpricing. Won’t say what I paid to have them replace a battery. Induction costs worth it to me.

  8. The service center I use recommended a fuel induction service and an evap canister vent valve. My 2015 Rogue is running pretty rough, stuttered and struggled to get to 30-40 mph this morning. I’m thinking the fuel induction service will take care of the problem, but is it your opinion that I should get the evap canister vent valve replaced as well? It’s double the cost of the fuel service, so if I can hold off on it, I will. Thanks in advance for any advice!

  9. My 2017 Kia Sportage has 24,000 miles. The dealership ids recommending fuel/air induction service. This seems a bit soon to me.?.?.

  10. The dealership recommended this service, saying it “failed” on inspection (not state inspection). Funny enough, I had noticed acceleration being slightly delayed in the past month or two. It idles smoothly and has no vibration when giving gas. I’m not sure about the mileage because I haven’t been driving due to stay home orders. If my car has just one of the 5 signs/symptoms you listed, does it need the service?

  11. I purchased a 2015 Hyundai Santa Fe Sport 2.0 Turbo in December of 2018 from a Hyundai dealership and even purchased the Hyundai extended warranty . The car had about 32,000 miles on it when I purchased the car. Prior to purchasing it I test drove the car a couple of times and even kept it overnight to drive it more in order to see how well the car drove on the highway and in the city and I payed special attention to the mileage per gallon to see how the fuel economy was. I was very pleased with the results and felt the car was pretty efficient with fuel consumption. I decided to purchase the car and right before purchasing the car I realized there was an update to the engine that was never done by the Hyundai dealership (it was noted on the Carfax). I asked about the update and they apologized that it wasn’t done and said that it was an oversight and they would make sure it was done before I picked up the car. The update was done and ever since then the cars fuel economy is terrible. The car seems to suck gas like crazy. I brought this to the attention of the dealerships service department at the first scheduled maintenance appointment and was told it was because it’s cold out so the car needed to use more gas to warm it up. The next service appointment was during the late spring and I again voiced my concerns about the gas mileage. This time I was told it’s starting to get warmer so you are probably running the air conditioner more. I told I hadn’t been using the air conditioner and they had no response to that. Now they are telling me that they noticed my car was running a little rough and that my car needs a fuel induction service. They said I don’t know if you’ve noticed you’re using more fuel than normal but if you have this done you will find your car will be more efficient with fuel consumption. I’m very frustrated because I feel like something has been off with the engine since the update was done and I’ve been getting the run around. Have you heard of this happening with this car model after the engine update recommended by the manufacturer? Do you think the fuel induction service should be done and would help my situation?

  12. I have a 2017 Cadillac XT5 with just under 50,000 kims. My mechanic (the dealer) is “recommending” I get this service. I would think that with such a new vehicle and low kms, this should not be required yet. What do you think? Thank you.
