What Is A Fuel Additive?
Now before we dive into the types of fuel additives and the best fuel additive, let’s first learn more about the fuel additive in general and learn more about the basics. This chapter will be a good starting point for you before you try to understand more about the different types of these additives and what they do. So, let’s get into it.
A fuel additive is a special chemical solution that is used to improve the engine’s performance. As you probably are aware. Engines and cars get old and start to perform quite poorly.
There are many different systems that are affected by this type of wear and tear. The fuel tank, fuel lines, injectors, and even the combustion process will be much worse on a worn-out engine.
This is why there are some solutions known as fuel additives to improve the performance of the engine and make it perform slightly better than normal.
When you pour a fuel additive, you will notice an improvement in performance. And let me tell you a secret. Some car sellers are pouring this additive into their cars for sale to make them perform better. And after the additive starts to disappear, you will see its downsides.
But what are the types of fuel additives that are available out there? Knowing this will be extra useful for you to know before we learn more about the best fuel additive out there.
Types Of Fuel Additives?
Now in the following chapters, let’s elaborate more on the types of fuel additives. Knowing the types will help you learn what you really need.
Since not all additives are doing the same type of work and have different purposes based on the problem that you are dealing with. So, let’s cover them really quick before we dive into the best fuel additive topic and learn which ones are the best in certain categories.
1. Fuel Conditioner
The first type of best fuel additive that we are going to cover is the fuel conditioner type or fuel treatment as some people call them. Fuel conditioners are the most popular additives and also one of the cheapest additives out there that you can purchase.
As their name implies, they are fuel conditioners. Which means that they help your vehicle perform better. They are formulated to work on diesel and gas engines. But still, you need to learn the description and check if this solution works on both types of engines. Just to be sure.
These types of conditioners are used by a ton of owners to pass smog tests. They neutralize carbon deposits and bring cleaner emissions. Thus, helping you to pass the emissions testing. So, if you have a car with a bad catalytic converter. This type of best fuel additive is perfect for you.
2. Fuel Stabilizer
The second type of best fuel additive that we would like to cover is the fuel stabilizer. The fuel stabilizer is a specially formulated type of additive that has the sole goal of preserving the fuel inside of the gas tank.
This type of additive is perfect for cars that are not driven a lot. So, if you have a classic motor that you don’t drive too much and you want your gasoline to stay fresh in the long run, using this type of additive might be the best solution for you.
Some of these additives are promising a lot. Up to two years of the freshness of the gasoline in your tank. And considering that gasoline only lasts up to six months on average, then this best fuel additive will be perfect for you.
So, if you have a classic motor or a car for storage, you should go for this type of additive for your car without a doubt.
3. Octane Booster
The next type of best fuel additive that we would like to cover is the octane booster. The octane booster as its name implies is a special additive that serves the purpose of boosting the octane rating of your car.
This additive is especially good if you are running a high compression engine like a race car for example. Gas pump octane ratings are pretty low and you need something for the track that will give you that extra edge and squeeze every last bit of performance from your engine.
And this is why octane boosters are perfect for this. These octane boosters come in small cans of 6.7 oz which is good enough for a full tank of gasoline.
They also promise that they will clean the engine from carbon deposits and other debris that usually collects on the valves and injectors. But still, their prime task is to boost the octanes as well as the performance of your vehicle. Now let’s move to the next type of best fuel additive.
4. Fuel Injector Cleaner
The next type of best fuel additive is the fuel injector cleaner. The fuel injector cleaner is one of the most common types of additives that are used on cars.
This is the case because a ton of people are having problems with their fuel injectors. Especially cars with a ton of miles that have a ton of gunk accumulated on them.
When there are obstructions on these injectors, the flow of fuel will be quite poor and the car will simply fail to deliver. This is why using a solution like this can save your life. I mean literally.
A ton of owners report significant changes after using solutions such as Seafoam that clean the injectors and also improve the combustion. So, if your car underdelivers, this type of best fuel additive might be really good for you to avoid dealing with a problematic vehicle.
5. Catalytic Converter Cleaner
And the last type of best fuel additive is the catalytic converter cleaner. Believe it or not, there are also solutions that promise to clean your catalytic converter as well.
You just pour them into the gas tank and they will work to eliminate the debris that clogged up inside of the catalytic converter.
Even though their effectiveness is doubtful. Still, it is a good idea to try them out if you have problems with a clogged converter. If the problem is just starting, you might solve the issue quickly. If not, you will have to replace the converter. Simple as that. Now let’s cover more about the benefits of these solutions in the next chapter.
Benefits From Using A Fuel Additives
Now before we dive into the best diesel fuel additive (once you’ve figured out why is diesel so expensive) and learn all the best additives that are out there in certain categories. Let’s first learn more about the benefits of using additives. What can you expect from these additives in the first place? Will your life change after you start using them?
Well, they will help your car. That’s for sure. Some of them will work better than others with your specific engine and this is why you should not disappoint yourself if the additive that you purchased isn’t working well. Just try a different solution and you will see the benefits right away.
Also, these additives will save you a ton of money on engine cleaning if the engine is old and has a ton of carbon deposits. Some of the additives such as Seafoam as we mentioned are all in one, they will increase the power, improve the lubrication and the engine will live its second life.
The benefits of these solutions for older cars are enormous and you should never be afraid of using an additive if your car is older than 15 years or so.
Not to mention that these solutions are not only for your wallet but also for the environment. Your car will highly likely pollute less when using this type of additive and you will pass the inspection without any hiccups.
But using this best diesel fuel additive is not recommended always. And in the next chapters, we are going to learn when you should use it on your car if you want not to harm your engine.
When You Should Use An Fuel Additive?
So, when you should use the best fuel additive in your car? Well, this greatly depends on the specific purpose.
For example, using additives on newer and low mileage cars really makes no sense at all. Since these cars have good engines that are not worn out. So, the benefits of using an additive on a car like this will be minimal or almost inexistent.
Additives should be used in older vehicles that are nearing their end of service and this will be a way to extend their life for a little bit longer and squeeze every mile out of them.
So, if you have an older car that has trouble passing the inspections, then this solution will be the way to go. Another example is a car with fuel injectors that do not work as they should and the car jerks and hesitates because of the poor performance of the fuel system. In this case, using the additive will give this system a good cleaning and the car should work well again.
Also, if you have a car that is intended for long-term storage. Then using the best fuel additive to extend the life of the fuel in the gas tank might be an excellent idea.
And lastly, the octane boosters should be used if you are using your car for the track and you cannot squeeze the most performance from your engine on those long track days with regular gas. So, an octane boost might be the way to go. But what is the best diesel fuel additive? Let’s see more on that next.
