“The list of best fuel injector cleaners below will help you pick the most suitable additive for your vehicle”

I remember the last time I went to the mechanic to have my car’s injector cleaned after my (unsuccessful) attempt to do it on my own. The job was executed by a professional who must have done it hundreds of times and success was guaranteed. As you can see, it went well for my car, but not for me and my wallet. I had to pay through the nose for that well-done job, relinquish with my car for quite some time, and with my financial situation back then, one can hardly say the experience was pleasant.

After that incident, I decided to take the matter into my own hand and learn a bit about car maintenance myself. I don’t claim to be an expert in this field but after countless hours surfing the Internet and several trials and errors to verify what I found, I’m confident that the list of best fuel injector cleaners I’m going to share here will come in handy to those who wish, to some extent, be able to take care of their own vehicles. In this article, I will talk about fuel injection cleaners only, which I think if done right, can save you a ton of your hard-earned money and prolong your car engine’s life.

How does fuel injector cleaner work

Despite what you may think, the gasoline you regularly bump into your care isn’t pure, it is filled with additives that can form a thick layer of deposit after some chemical reactions. To put it simple, imagine a campfire. The wood you put in is turned into fire, smoke, and coal. This is what happens inside your car engine. As gasoline produces energy (fire) and gas byproduct (smoke), it leaves behind some unwanted solid deposits inside your engine and fuel lines. Basically, fuel injector cleaner is blended into your gasoline; dissolve any buildup in the injector and fuel lines. The solvents are then burnt away in the combustion process. 

There are three main components of any fuel injector cleaners; each has its own functions and best use case scenario. I recommend paying attention to them so that you know which cleaner to use for your car:

Polyisobutylene

This compound is more commonly appear under the name PIBand can be used in both diesel and gasoline fuel injector cleaner. It clears away buildup in your car’s injectors and fuel lines. Research has shown that PIB can reduce the chances of engine knock and misfiring.PIB can also be found in some gas treatment, which is added to the tank before filling up to improve the quality of fuel. It rids your fuel of harmful chemicals such as carbon deposits and water.

Polyisobutylene Amine

Known as PIBA, this agent is somewhat similar to PIB. One difference is that it is more effective in removing moisture. It doesn’t show much effectiveness in cleaning the combustion chamber so don’t count on it to clear away long-term buildup or sediment deposits.

Polyether Amine

It is more commonly labeled as PEA, this compound is the strongest cleaning agent available on the market and appears in most leading fuel injection cleaner brands. It can clean up more parts than PIBA and PIB. PEA also proves itself to be the safest and most neutral solution to enhance both the balance of fuel and the car’s performance.

Should I Use Fuel Injector Cleaner?

I asked the same question when I first got myself familiar with fuel injector cleaner. Is it necessary for car maintenance or just a vehicular snake oil? But this guy had convinced me to give it a go. He is Duane C. Richardson, technical service engineer of 3M’s automotive aftermarket division. He warned anyone who makes a lot of short trips in cold weather, the kind of condition that candouble the problem of carbon deposit buildup.

Here I answer the question of whether you should use fuel injector cleanerby showing you what will happen if you don’t.

Engine misfire: an incomplete combustion event can be caused by a poor mixture of fuel and air. This can lead to the cylinder to miss a stroke and then an immediate loss of power. This can come to the point that you can notice the engine shows a jerking action.

  • Rough engine idle: If the injector just starts to clog, you will feel a rough engine idle but the vehicle will still run normally under acceleration. However, if you leave it that way up until the point that it is completely clogged, it will create engine misfire all the time.
  • Increase or reduce injector pulse width: Your vehicle is designed to run with a certain injector pulse width according to an array of factors. When the fuel flow is restricted (or blocked), the engine controller will open the injector longer than usual, you may notice this by a fuel smell coming from the engine compartment. Sometimes the buildup can prevent the injector pintlefrom shutting down completely causing a fuel leak.
  • Poor fuel economy: If the injector fails to provide enough fuel, the ECU will compensate by over-fueling, which will harm your wallet.
  • Your vehicle won’t start easily: A leaky injector can cause a drop infuel pressure in the fuel rail and make your vehicle hard to start or won’t start at all.

I have conversed with a number of other drivers who notice these symptoms in their vehicles but most of them assume that their cars stagnate and consume more fuel because they’re getting old. A clogged fuel injector is the last thing they think of.  But don’t get me wrong, I don’t imply here that fuel buildup and impurities are the main culpritfor the aforementioned problems. There are other variables in play. So keeping up on preventative maintenance itemsto ensure your car operates as it should.

What is the best fuel injector cleaner?

It goes without saying that one size doesn’t fit all and one fuel injector cleaner cannot be compatible with every vehicle. I have learned in the hard way that it is not about the most expensive one, but it is more about the most suitable one for certain vehicle. Here I will show you what to do to land the best cleaner for your car, from my own experience:

  • Pay attention to the temperature of where you will operate the vehicle

Irrelevant as this may sound, the temperature plays a huge part in determining what type of fuel injector to choose. Some detergents can withstand either high or low temperature and some can work well in both. Think of where you will drive your car the most and pick the suitable cleaner. In this way, you won’t waste your money on something you don’t need.

  • What type of fuel your vehicle runs on

There are fuel injector cleaners that are designed to work with some specific type of vehicle, which you should pay attention to. When shopping for cleaners, find out about each detergent is compatible withwhich type of vehicle. Depending on whether your vehicle runs on gasoline or diesel, pick the right cleaner because the wrong one cannot generate the best result. If you make the right decision, your vehicle will response by giving you better performance and better fuel economy, which you can feel after a few days of applying the cleaners.

  • What your engine components are

Port fuel injectorsprays fuel at each intake port rather than the central throttle-body. When deposit forms on this component, it can obstructthe spray and cause large droplets which are hard to combust. With direct fuel injection system, the port is exposed to a huge amount of heat, which can bake the deposit onto fuel system components. When this happens, you will need a stronger detergent. Know exactly your engine components and pick the most suitable product that yields the best result for your car.

  • Know what formula you need

Some of the information on the product’s label can be straightforwardbut some are not so much. If the label states that the solution should be added along with every fill-up, it is generally weaker than those with a longer interval between applications.

Fuel injector cleaner’s functions aren’t limited to clearing away deposits. They may contain lubricants and friction modifier to improve your vehicle’s general health. A thorough understanding of formulas, cleansing power, and the treatment rate will help you get the most out of what you pay for the cleaner.

  • Pay attention to the chemical components

There are certain cleaner brands nowadays that have a very high percentage of other additives, instead of the three cleaning agents. I recommend opting for the one that contains one of these compounds. Before buying a fuel injector cleaner, make sure that these 3 agents are in there:

Polyisobutylene Amine (PIBA) - Polyisobutene (PIB) - Polyether Amine(PEA)

Alternatives to Using Additives to Clean Your Fuel Injectors

There are some fuel injector cleaner alternatives, but some of them are quite inconvenient and should be required only when your fuel system is heavily affected by buildup and blockages. It can remove completely the dusk and clean your car injector by using solvents that are forced through at high pressure. The process is cannot be achieved at home and you will need a specialist to deal with your injector, or you can take the car into an auto shop to have the work done. It is obvious that you need a proper production line to ensure that your car injector is clean and well performing! Depending on how many cylinders your vehicle has, this work could become relatively expensive. There’s a fuel injector for every cylinder on your engine, and if your engine is particularly difficult to work on, then you will also face increased labor costs to have the work completed.

1. Fuel injector cleaner vs Premium fuel:

The first and foremost alternative for the best fuel injector cleaner must be the greater fuel efficiency, which help to reduce component wear and improve reliability. To this end, the oil companies have been introducing additives designed to eliminate the minority of unwanted deposits that build up in your engine over time, extend the life circle and maintain an effective performance. The tech behind may be highly sophisticated but the principle is simple to understand: the newer is better!

Firstly, take the recommendation for you (specific) vehicle from your manufacturer. They are the one who know what is best fit for your car and these can be found easily and fully on your vehicle handbook or available online. Secondly, check on your car, if it is relatively new, you can improve your engine life with the premium fuel. Higher octane fuels are also suitable in case you are using higher compression engines. Again, check up with your manufacturer specs if you are not sure about your car’s information.  In case that you are running an older car, a regular and non-premium fuel is likely a better choice. You will gain no additional benefit from running premium fuel or a higher octane, and whatever deposits have built up over the past couple decades won’t be remedied by fuel additives. Your car’s fuel system and engine is full of cavities and delivery lines that are prone to build-up of carbon and other deposits. As these deposits build up over time and use, your engine has to work harder to maintain performance and its many components become increasingly susceptible to premature wear. And, if you are owning a relatively modern car, here are the key benefit you will take from using premium fuel:

  • Building up carbon

Carbon build-up extracted from a modern Audi engine after only 60,000kms. Think about the arteries in your body and valves in your heart and what they going to clog up when you are in serious trouble. The car’s engine works exactly the same. That is also the reason why many car’s producers invest a lot on researching and producing fuel that is specially tailored to eliminated these deposits and prevent further build-up.

Here is the image for an intake valve with a pretty typical amount of carbon build-up with a conventional electronic fuel injection:

Figure 1- a pretty typical amount of carbon build-up with a conventional electronic fuel injection

Figure 1: a pretty typical amount of carbon build-up with a conventional electronic fuel injection

If choosing the right fuel, the dust overnight on your car’s system won’t look that bad! Given that reliability is the key factor for considering a relatively new car which is sticking to a premium fuel.

  • Clean car’s fuel injector

It is obvious that a cleaner fuel injector will function better than a dirty one. The unimpeded fuel will deliver through the injector, which means that a cleaner one will run your car smoother and longer! 

Figure 2: a cleaner one will run your car smoother and longer

Figure 2: a cleaner one will run your car smoother and longer

So the next time you’re filling up, debating whether there’s any point in shelling out the extra few dollars to run premium fuel, consider what’s best for your vehicle, not your wallet. Engine repairs are far more expensive than the cost of picking up the premium pump.

2. Fuel injector cleaner vs Carb cleaner

As mentioned above, a dirty fuel injector is a bit off, however, what the “dirty” things come from? The answer is a build-up of fuel varnish deposits. When the fuel isn’t properly flowing, with just a little amount, it will cause misfire, hesitate or stall for your vehicle. Ethanol in gasoline can also lead to developing deposits and clogged fuel systems.

Figure 3: Ethanol in gasoline can also lead to developing deposits and clogged fuel systems.

Figure 3: Ethanol in gasoline can also lead to developing deposits and clogged fuel systems.

Despite of being highly debated among car enthusiasts as to which offers the best performance, fuel Injectors and Carburetors work relatively the same. Indeed, fuel injectors do just nothing more than a spray nozzle in the intake manifold while a carburetor sits on top of the manifold and uses jets that meter gas into the intake manifold. However, regarding to its drivability and easy starts though, fuel injection seems to be preferable.

And the problems occur when the system is stuck in build-up of deposits, caused by a small jet. For that reason, a fine cone-shaped mist of fuel vapor is necessary. Paying for a quality gasoline brand with the proper octane rating (effect your vehicle performance) and using quality fuel additives are the best ways to avoid these build-up! Some recommendations for you are 104+ Octane Boost® and STA-BIL® Ethanol Treatment.

Those are concentrated cleaner, which is accumulated varnish deposits if they are added with proper fuel and pass through the injector or carburetor to loosen wash. They burn out deposits in engine combustion and result in idle smoothness, emissions and fuel economy. Therefore, both fuel injector cleaner or carburetor cleaner products are safe to use every time you fill your gas – especially if you use a lower octane fuel.  Use of these cleaners is highly recommended if your vehicle feels sluggish or less responsive.

3. Techron fuel system cleanervs injector cleaner

Let’s look in further detail at Techron Fuel Injector & Fuel System Cleaners respectively. Obviously, the packaging and marketing literature did introduce the techron fuel injector as an injector lines directly, as what the injector cleaner does. Both additive are highly flammable and heavily solvent based. Basically, the solvents aren’t dissolving carbon deposits but they readily evaporated and combust.  As a liquid and vapour, they all ignite!

Figure 4: Techron fuel system cleaner

Figure 4: Techron fuel system cleaner

Specifically, techron fuel injector Cleaner is formulated and added with a full fuel tank, in order to keep fuel injectors free of carbon deposits. The cleaning and corrosion inhibiting properties aren’t listed as same as fuel system cleaners and it might not include the inclusion of a friction modifier or lubricity additive. Based on the differences in listed chemical components, the injector cleaner and the techron fuel system cleaner are different products. The second product appears to have a higher concentration of cleaning detergents or solvents, while the first one is primarily made from petroleum fractions. it is abundantly clear and contain a large number of toxic & carcinogenic chemicals that you do not want to ingest or contaminate food with accidentally! It acts like a preventative to clean carbon deposit forming as well as other minor formations. And you can choose to drop in some fuel treatment, especially on direct injection engines with emission control systems. Here are two options for you:

  • If your vehicle isn’t suffering too much from the effects of carbon build-ups and you intend to clean the whole fuel system, including the injectors, use the fuel system cleaner regularly.
  • If your vehicle is smoking heavily, is slow to pick up when accelerating and you’ve noticed a drop in fuel economy, then try the injector cleaner first.

It effectively breaks the bonds of solid deposits on a molecular level and turns the deposits into harmless ejection and then passes all through the combustion chamber. Another advantage of component is that it is absolutely no residue left in the fuel lines, injectors, or within the engine.
  • Polyisobutylene Amine: labeled as PIBA, which is similar to PIB, but more effective in removing moisture. However, its weakness is the ineffectiveness in cleaning the combustion chamber. Therefore, it is mostly used as a maintenance product.
