Fuel injectors are the all-too-necessary communicator between your gas tank and your engine.

They’re an incredibly important component of your car, one that is used every single time you start your vehicle.

Keeping your fuel injector clean keeps your mileage accurate, minimizes engine noise, reduces emission output, and keeps your car in good working condition. 

The right cleaner enhances your car’s performance, and fuel injector cleaners make an enormous difference in the overall quality of your vehicle and its continued maintenance.

Do I Need To Clean My Fuel Injector?

Clogged fuel injectors reduce overall engine performance in a number of ways, responsible for a variety of engine woes including:

  • Mileage Reduction
  • Starting Issues
  • Acceleration Problems
  • Rough Idling
  • Stalling
  • Throttle Choke
  • Increased Emissions
  • Excess Emissions

Does Fuel Injector Cleaner Really Work?

Maintaining your fuel injectors means enjoying the peak performance of your vehicle.

Since your fuel injector is a critical component of your engine, you will need to know how to clean them and maintain that there are no outstanding issues.

Fuel system cleaners are efficient and help stop new blockages from forming.

While not scientifically proven, the claims made for them by those with experience show they are an important aspect of maintaining vehicle longevity. T

hey aren’t always potent enough to remove massive deposits, but their efficiency speaks for itself.

There are lots of different kinds of fuel injector cleaners, they are typically very affordable, and you can try out a new bottle in your gas mixture when you’re experiencing a potential issue.

Consult an expert for more information on fuel injector cleaners and their performance.

Types Of Fuel Injector Cleaner

Dissolvents are the most common type of cleaner. Dissolvents commonly use Polyether-Amine (or PEA) to break down increased carbon composites.

Fuel impurities build up over time on the vehicle’s injector and combustion chamber, and dissolving that building enables them to be safely ejected through the car’s exhaust system.

Dissolvents are the most common type of fuel injector cleaner because they attempt to do what your vehicle is already doing.

Detergents are the less common form of fuel cleaner.

Most people remain convinced that dissolvents work better than detergents, and there are some discussions about whether or not detergents actually help to clean your fuel system.

Detergents work by triggering chemicals that force carbon deposits to exit your fuel system.

The Benefits

  • Gas Mileage: Cleaning your vehicle’s fuel system of carbon deposits improves gas mileage overall, which benefits both the environment and your wallet.
  • Performance: When you keep your engine in good working condition and free of deposits it means you will see the results you want. Using fuel additives helps maintain the full potential of your vehicle.
  • Lower Maintenance Cost: While it may feel like yet another added cost, frequent use of additives on your vehicle will actually lower the overall necessity for maintenance. Keeping track of your car’s mileage, type of fuel, and how often you use a fuel cleaner will showcase optimum results.

How Do I Use a Fuel Injector Cleaner?

You need to choose the best fuel injector cleaner for your vehicle. While it may seem like a “one size fits all” situation, there are subtle differences in vehicles that can ask for different cleaners, so it’s best to consult your owner’s manual.

There are a couple of ways to use fuel injector cleaner. While some car enthusiasts remove the injectors to clean them, this can be a problem if not done correctly and is a step best handled by your trusted auto mechanic.

Always follow the labeled instructions, as the actual functionality of the cleaner can vary. Some fuel injector cleaners need to be poured directly into the tank and others need to be diluted first. 

Before you go ahead and insert the cleaner into your vehicle, make sure the fuel tank is empty. After adding the cleaner, add fuel in equal proportion to the amount of cleaner.

Then take your car out for a short drive and see if you notice the changes (they should be immediate).

A few cleaners might involve additional procedures, such as asking you to idle your vehicle for a short amount of time.

One of the things that can clog your fuel injectors is impurities in gasoline, so you may need to maintain the quality of gas that you purchase.

Check the function of your fuel injectors regularly by popping the hood of your car and taking a peek at the combustion chamber to see if there is a spray pattern releasing from the injector.

In some cases, the injector may need to be removed and cleaned. This step should be handled by your local mechanic.

You should use a fuel injector cleaner after every oil change once you get into the habit of using it at ~10,000 miles. The actual distance may vary according to the age and model of your vehicle. 

What Is The Price Range For Fuel Injector Cleaners?

Volume is the primary factor determining the price of any fuel injector cleaner. A 6oz cleaner has prices that range around $5, and 16oz cleaners vary around $25. You will find that the bigger 32oz cleaners reach $35. 

If you’re looking for Honda parts online in Canada, make sure you don’t stop at your fuel injectors. Every piece of your car adds up to the total longevity of the vehicle.

Typically these cleaners will pay for themselves in the mileage you save. After the very first use, you should notice a difference, even if you follow the basic instructions and pour the cleaner directly into your tank.

Again, if you don’t notice a fairly immediate change you should take your vehicle to your local mechanic so that the fuel injector can be cleaned and replaced.
