Sifting through the choices to find the right one is going to be frustrating. If you don’t have the time (or the inclination) to learn all about this type of cleaner and what it should be able to do, then we’ve got just the list for you. We gathered a lot of the most popular fuel injector cleaners available and flushed out (pun very much intended) the ones that didn’t perform well.

If you have an old car with serious problems or a relatively new one that hasn’t been properly cleaned, this is the fuel injector cleaner for you. However, it is a bit on the pricey side compared to similar products. Also, this is very strong stuff which can damage your fuel lines if you use too much.

However, this is not ideal for use with cars that have “sludge” in their oil or those that do not have regular oil change as it may clog the fuel injectors. And it does not contain any PEA which means it probably won’t work as well in removing years of carbon buildup in older, neglected vehicles.

How to Choose the Best Fuel Injector Cleaner: The Ultimate Buying Guide



Your dealer or mechanic has been telling you that you need an injector flush which costs $80 to over $100 unless you want to end up with a $1000-bill for a fuel injector replacement. Fortunately, there’s a DIY solution which is just a fraction of the cost of a flush – a fuel injector cleaner. Now, most of us likely have no idea what that really is and how it works, just an inkling of what it does (cleans the part that injects fuel, right?).

But how do you know which one would work best in your car? There are quite a lot of different brands on the market, all of them offering a wide variety of benefits should you use them. Naturally, you want the one that will make your car run smoothly and prevent the need to buy a replacement fuel injector. The problem is finding which one does exactly that. Well, to help you figure out fact from fiction (in other words, marketing mumbo-jumbo), our shopping guide should give you all the information you need to make the right choice.

What Exactly is a Fuel Injector and Why do I Need to Clean it?

Most cars feature a fuel injection system which is a method of delivering fuel. Using high fuel pressure, a fuel injector will open its valve and pump small amounts of gasoline or other types of fuel through a nozzle which atomizes the fuel into a fine spray, ensuring it mixes well with the air before it goes to the combustion chamber.

Now, fuel isn’t exactly clean; it’s full of contaminants. It also isn’t chemically stable. And then there’s the carbon residue that is deposited by gas and diesel. Combined with the microscopic particles (contaminants) in fuel, you’re going to have a lot of buildup in your fuel injector which can affect its high-pressure spray by inhibiting its flow. This can lead to poor engine performance, increased emissions, increased fuel consumption, hard starts, etc. Obviously, you’re going to want to get rid of these deposits and that’s where the fuel injection cleaner comes in.

How Does a Fuel Injector Cleaner Work?



A fuel injector cleaner gets rid of any deposits that have formed in your fuel injector. In fact, some fuel injector cleaners are effective enough to clean the entire fuel system. It loosens, breaks down, and/or dissolves the deposits so that they can either be washed away or burned during the combustion process.

What’s in a Fuel Injector Cleaner?

While formulas may vary depending on brands, these cleaners are basically composed of detergents and oils for cleaning and lubrication, respectively. The most common ingredient in all cleaners is PEA or polyetheramine which is the most effective in getting rid of carbon deposits. This chemical dissolves the deposits so that it can be safely washed away through the engine’s exhaust system. An added benefit of PEA is that it can help prevent additional deposits from building up because of it is a surfactant.

Because of PEA’s effectivity, you need to make sure that the cleaner that you choose contains this ingredient at a level that is not too diluted to be effective. The Red Line Complete SI-1 Fuel System Cleaner, for example, has the highest concentration of PEA in all of our picks. Take note that some cleaners will have polyisobutylene amine (PIBA) as its main ingredient which can also effectively remove deposits within your fuel injector. However, it is not as powerful as PEA which can clean an entire fuel system though it costs a lot less.

Factors to Consider When Choosing

Suitability: not all fuel injector cleaners will be compatible with your specific engine. Some will work with both diesel and gasoline but it’s still important to check suitability before making your purchase. If you have doubts, ask your mechanic or the people at your local auto shop. The Chevron Techron Concentrate Plus Fuel System Cleaner, for example, is suitable for all types of gasoline engines such as those found in motorcycles, boats, RVs, lawnmowers, etc.

The frequency of application: this refers to how often you will use the cleaner. Some manufacturers recommend use with every fill-up while others like the BG 44K Fuel System Cleaner will have longer intervals between application.

Cost: fuel injector cleaners with an effective amount of PEA typically cost more though they require a less frequent application. Cleaners that need to be applied frequently like the Lucas Fuel Treatment, on the other hand, tend to cost less.

Brand: it’s important to take into account a brand’s reputation when choosing a fuel injector cleaner. No-name brands may not produce the results they promise. Reputable brands, on the other hand, will spend more on R&D to ensure that their product is effective. This also assures you that the amount of PEA in the formula is significant enough to make a difference in your car’s performance.

Tip: some fuel system cleaners are also compatible with carburetors. This may be an ideal choice for you if you have more than one car.

Some People Claim That They Don’t See a Difference in Performance. Why’s That?

It’s quite possible that you bought the wrong product for your car. But even if you don’t see a noticeable difference, it doesn’t actually mean that the cleaner isn’t working at all. Unless your car is already showing symptoms of a clogged fuel injector – poor performance, hard starts, failed emissions, poor idle, etc., you probably won’t see much of a difference. However, prevention is better than cure. If you want to prolong the lifespan of your vehicle, you’re going to want to apply this cleaner from time to time. Take note that you should always read the instructions thoroughly and follow the manufacturer’s recommended dosage. Not all fuel injector cleaners work the same way.
