The unfortunate thing, however, is that many of these changes are temporary. You need to use this product quite often to be able to see continuous results.
On a similar note, the value with this cleaner isn’t great. This is because a 12-ounce bottle will be able to treat only about 20 gallons.
If you aren’t using fuel that is all that great for your vehicle, then you should definitely consider utilizing this cleaner. This is because it offers up a deep cleaning action that is sure to get rid of whatever deposits that may have built up on the surfaces of your internal system.

Since the intake valves will be all cleared up, you will notice that your vehicle is able to start up with no issues at all, even if it has been idle for quite a while. There will also be an increase in power and speed, allowing you to get a lot more out of your car. In general, it will be a great deal more comfortable to drive your car around.
The one thing that we didn’t really notice with this product was too much of an improvement in fuel efficiency. Of course, we did use the bare minimum so with a little bit more input, you may be able to see better results.
This fuel system cleaner doesn’t offer up the greatest value, particularly at this price point. One ounce of this 12-ounce bottle is enough to treat a single gallon. Now, since you may need a lot more to be able to experience fuel efficiency, this cleaner may be a bit pricey for most people.
Guide to Buying the Best Fuel System Cleaner
In this section, we will talk about how you can choose the best fuel system cleaner for you:
Fuel System Cleaners vs. Fuel System Injectors
Now, one of the things that you need to know is that carbon build-up and other types of deposits in your internal system can affect a number of components in the car. This is why you may have come across a product known as a fuel injector cleaner during your search for an appropriate product.
While some people may tend to use the terms ‘fuel system cleaners’ and ‘fuel injector cleaners’ interchangeably, there are some differences. The main variation that you need to focus on, though, is the function. See, fuel injector cleaners focus largely on the injectors in your vehicle. A fuel system cleaner, on the other hand, is involved in cleaning out the fuel injectors, carburetors, portions of the engines, pistons, and more. So, as a result, you can get a more widespread cleaning.
The various additives are explained in greater detail here:
Ingredients to Consider With a Fuel System Cleaner
Before going any further, you should be aware of the ingredients that are used in these cleaners and which ones you need.
In most fuel injector cleaners and fuel system cleaners, you will come across the term polyisobutene or polyisobutylene amine. These components are more commonly referred to as PIB or PIBA. While they have similar functions, their cleaning power is what’s different.
See, PIB is more suitable for prevention of build-up. In fact, one of its main features is the removal of the water in the internal system of your car. So, if you have only recently changed to a cheaper fuel or you have a new car and want to maintain it well, then PIB will be useful for you. Where this cleaner falls short is with deposits that already exist. In this instance, the PIB is not powerful enough to remove this type of build-up.
The ingredient PIBA, though, is well-suited to such situations. It tends to be more potent than PIB which is why it is often used to tackle moderate levels of deposits in the internal system. It is also quite useful to clean a greater number of parts. Furthermore, if this ingredient is used properly, you shouldn’t have to use a cleaner all that often.
Now, there are some vehicles that have been running for years on cheap gas or just have simply been contending with large, difficult-to-remove deposits. In these cases, you can actually notice that the performance and efficiency of the car have been greatly reduced.
Here, you are going to need to turn to what is known as polyetheramine or PEA. This is the strongest cleaner of them all and is also capable of cleaning a greater number of components within the system. All of this combined makes it one of the best cleaner ingredients that you can find. So, if your vehicle is in a really bad state, this is what you will need.
Of course, when looking at the label on a bottle, you can’t just buy a product because it claims to contain PEA. You also need to look at the percentage of PEA in that cleaner. The worse shape that your car is in, the more PEA that you will require.
What to Look for in a Good Fuel System Cleaner
Here are some of the other factors that you will need to look at with your fuel system cleaner:
Deep Cleaning Action
This does depend on how badly your internal system is doing. If you hear knocking and pinging sounds or are experiencing serious problems, you will require a bit more cleaning power. These products are also often a good choice for older vehicles that haven’t been well maintained. Here, it may be beneficial to you to look for cleaners that contain the label ‘Deep Clean’. These are often equipped with stronger detergents and cleaning agents that can deal with deposits that are not easily dislodged. This may not be required, however, for simple maintenance.
Improved Fuel Efficiency
You should always look for products that will improve your fuel efficiency. Now, in most instances, this is an automatic symptom of an internal system that has been cleaned up. Once all of the build-ups have been removed, you should be able to drive for longer on the same amount of fuel.
Still, products that specifically mention improved fuel efficiency can often be considered an overall system cleaner rather than just focusing on a few components. In that sense, they tend to be a much better cleaning agent.
Lubrication or Conditioning
Now, it isn’t enough for you to just get rid of the deposits in the internal system. You also need to make sure that it will be a long while before they form again. One of the ways that you can do this is by looking for a product that conditions or lubricates the surface of the internal components. This way, the carbon build-up will find it difficult to adhere to the surface. The other benefit of such a feature is that you get to protect the various components from corrosion as well.
Each cleaning product will let you know how much of the bottle you have to use to be able to treat a certain amount of fuel. If you have a small vehicle or you just want a cleaner for maintenance purposes, this may not be such a big deal.
However, if you have a turbocharged or supercharged vehicle, you are going to need to pay attention to this. Value for money means that you will be able to use a less amount of the product for a greater number of gallons. This is why you should look for concentrated versions that can be used in smaller doses if you are driving a large gas guzzler.
While this may seem like an odd thing to consider, it is a good idea to take a close look at the shape and design of the container. After all, you will need to find a way to use the bottle to place the cleaner in the tank. Now, these cleaning agents are quite potent so they shouldn’t be spilled on the ground, the exterior of the car, or on you. Therefore, it is important that you easily and directly introduce the system cleaner into the tank.
This concludes all you need to know about fuel system cleaners and how to choose the best one.
