Octane Booster Buying Guide

best-octane-boosterThere are only a couple of tips on buying an octane booster and it is relatively easy to find the right one for your car.

3 Tips to Help You Choose the Right Octane Booster

  1. Don’t Get Fooled By Advertisements
    The octane booster is not some magical addition to your fuel which will make your car fly so don’t get fooled by ads and promises. The octane boosters on the marked added 5% more octane values to your fuel and that is the highest amount there is. The average is around 3% improvement over existing RON rating. But that is enough to prevent the engine from knocking.
  2. Do Not Expect A Big Improvement In Performance
    You will get a slightly better performance of your car but nothing significant and noticeable. On the other hand, what you will note is that your engine will work smoothly and fuel economy will be better. In some cases, the throttle response will be better also.
  3. Choose Octane Booster According To Your Car
    Different engines have different specifications and use different fuel ratings. If you have a small, low-performance engine which is not high revving unit mostly you do not need an octane booster but if you got a big, high-performance engine and high engine, octane booster is very important. The higher the octane value is the more you need the octane boosters to keep it on the wanted level.

Factors To Consider Before Buying an Octane Booster

Well, if you are reading this you probably have decided that you want to buy one of these power additives. But before that, we want to help you choose the perfect one for you and your vehicle. There are a lot of different factors you most definitely have to consider before buying an octane booster.

Factors To Consider Before Buying an Octane Booster

  • One of the most important factors is the performance. You need to be aware of how the octane booster you consider buying will boost the octane levels in your automobile, motorcycle, etc. As much as we would like to help you here, you will need to read a lot of books and articles, ask people from your surrounding and understand that different brands will offer different results, which most of the time are not true.
  • Almost every person nowadays is on a budget. If so, keep in mind that sometimes trying to save some money is not the best decision. Buying the cheapest octane booster may not only be of no use for your car but may also cause some major damage to it. Of course, there are a lot of products that have added costs without being a good quality product.
    That’s why, as we already said, next time you invite a guest over, ask some questions, see if anyone could give you some advice on what the best octane booster is, coming from experience. This market is really harsh on the buyer for there is no specific cost range for the products. You can find a bottle of octane booster that very little and then at the next store you can find a bottle that costs 4 times as much.
    The cool thing is that a lot of the manufacturers give you the chance to purchase more than one bottle at a time. Most of the products on the Internet come in case packs of 12 and therefore there is some conduction in the price.
  • The moment you decide on a booster, you will have to think about the size you want. This goes hand in hand with the fact that you also need to know how often you need to use it. Larger containers and multi-packs will save you some money because as we all know the frequency in which you use the booster will affect your wallet.
  • Compatibility is probably the most important factor you need to think about. Different octane boosters work with different cars. The engine you have dictates the choice you need to make when buying an octane booster. You have to make sure that the booster you are going to purchase is suitable for the type of engine you want to make more powerful. The best part here is that this is not a difficult task and you can relax. Most of the octane boosters work for a different range of engines. The easiest thing to do is to buy one that is compatible with almost every engine. Just make sure that yours is included.

We would like to give you some important tips to consider when buying an octane booster. The first and most important thing is not to expect a totally new car. Most of the advertisement you are going to see is total deceit. Five. That is the percent that the best quality octane booster can raise your octane values by. You will also be able to see the change in the engine knocking with the average boosters that will raise it by three percent. Everything else, though, is probably a huge lie. Miracles will not happen. You can’t expect some old wreck to turn into a Lamborghini. But you can expect that your gas mileage will be a lot better and your engine will work smoothly. Different engines have different specs, therefore different fuel ratings as well. The benefits from an octane booster will not be many if you are using a low-performance engine. But if your car has a high-performance engine the situation is a lot more different. The octane levels are of great importance to the overall performance of the engine.

Let’s say that you are devoted to the goal of improving the performance of your engine. Then you should definitely know that there are also fuel stabilizers that could help you reach this goal. You must not confuse them as they do different things for your vehicle.
As we know, when gasoline has been sitting a long time it would normally have some kind of failure. The contaminants and impurities formed by the gasoline may reach your engine. Well, the fuel stabilizers will help you prevent that. They use antioxidants to keep the excellent condition of the vehicle. Octane boosters, on the other hand, resist abnormalities that could appear.

For example, engine knocking which is an issue caused by low octane levels. Low gas mileage is also such an issue. So we simply have to increase the octane rating in the fuel of the vehicle to avoid them. You need to be sure that the cylinder is igniting when it is supposed to and higher octane levels will do so.
Don’t look so scared now, our team is sure that you will be able to find the perfect decision for your car. Theoretically speaking both of these additives will do you good. But if you drive your car almost every day then you need octane booster and nothing else.
We really hope that this information will steer you in the right direction. Skimping to much may not be the best option. You need to look at all the opportunities you have, consider the type of engine your vehicle has and see if the octane booster you have chosen is suitable for your vehicle. Then, of course, you need to know exactly how to use octane boosters, so don’t stop reading!

What is an Octane Booster?

What is an Octane Booster?The purpose of an octane booster is to increase the octane rating of the fuel, to stabilize it and by doing so to make the performance of the engine better. It is a chemical additive that will also help you prevent engine failure or any other problem connected to the engine. It pretty much always comes in a bright- colored bottle that you cannot miss or confuse with anything else.

The active ingredient of the quality octane boosters is methylcyclopentadienyl manganese tricarbonyl (MMT). For the people that care about the environment- do not worry! It is eco-friendly and does not harm emission control devices.

It is known that by raising octane in certain types of engines you will make their effectiveness better and increase their power. However, not many people know that this is one hundred percent true only for high compression engines. So if you have a sports car, race car or even performance car this is a perfect decision for you. The situation is slightly different, though, when we talk about normal, average cars. There are a lot of factors that can influence the performance of your vehicle. Most vehicles have specific octane ratings given to you by the manufacturer, so adding an octane booster to the fuel of an average car may not be the best idea. Such a car will find it hard to run on higher octane fuels because its purpose is not generating more power. Though the engine and the other systems in your not-so-powerful car may be gauged to work with gas in a specific octane range, it is not impossible to use an octane booster. A lot of people do it and they are happy with the outcome.

What Are the Effects of an Octane Booster?

The effects of an Octane Booster are so many that we don’t even know where to start. First, and most important, you need to be sure that you have chosen the right one and that your car is suitable for the usage of such a thing. Let’s not rush things, though. We will talk about this a little bit later, now let us give you some important information on the effect of this magical liquid.
Octane boosters improve the power of your engine for they increase the level of octane in petrol fuel. That results in better fuel efficiency, something that every driver wants. The anti-knock additives that the octane boosters utilize are also one of the reasons why your engine is running so smoothly. Every product adds a different amount of octane to your car. The best results, of course, are shown from the highest-quality premium octane boosters. The Octane Booster does not only make your car faster but by that, they eliminate engine stalling, knock and hesitation.
The good eminence your vehicle will have is due to the fact that the octane has a great effect on petroleum. The Octane boosters help for the perfect performance of your car in the output power. Therefore, you have to choose your octane wisely.

How Do Octane Boosters Work?

Octane Booster ReviewsIn order to explain to you how the octane boosters work we first must explain what is the octane index and what does it mean. The octane number is basically the measure of performance of the fuel. The higher the octane number, the better and it means that the fuel can withstand more compression before detonating inside the cylinder chambers.

Modern gasoline powered vehicles use fuel with octane ratings of 91 RON (Research Octane Number), 95 RON and 98 RON. There is also a 100 RON fuel but it is the high-performance type of fuel which is suited for race cars and similar machines and is not for wide use in regular passenger cars. Since this standard fuel types are common for decades, all manufacturers produce vehicles according to these standards.

However, the problems are when the fuel is not up to the standards and it has less than 91 RON index. It can happen for various reasons. Bad mixture straight from the oil refinery, water in the fuel or some chemical instability from long-term sitting in the barrel. In any case, fuel with less RON than can cause engine problems, most notably engine knocking.

If the disbalance of engine specifications and fuel used is big, the engine knocking can be severe and cause big damage. Most modern engines have a knock sensor a device that monitors the quality of the fuel and alters engine management specifications in order to avoid engine knocking. However, despite this engine will be under stress and perform less than it should with higher fuel economy if you use weak fuel with insufficient octane number.

In this case, octane booster is needed and it brings the RON octane index to the wanted level ensuring that the engine will work properly without fear of engine knocking, loss of performance or the high fuel economy. Some of the octane boosters on the market have a fuel stabilizer function which means that they will keep fuel stable and up to standards for long periods of time since the fuel itself will lose some its characteristics after sitting for more than a month in a tank or a barrel.

Using an octane booster is very simple and similar to the use of fuel injectors cleaning fluid. Just add the contents of the bottle to your tank and that is it.

How To Use Octane Boosters

Identify the octane level that suits your vehicle. You could do that by checking out the owner’s manual or just look underneath the gas cap. This will help you find out what octane grade fuel is best for your vehicle. Often times, cars tend to underperform if you don’t meet these octane levels. If you exceed this number, you will also not get the best results and your car will probably underperform again. That is the reason why you need to know exactly how much booster your vehicle needs!

Choosing the Right Octane Booster is of great importance. This is where all the things we talked about come in handy. You need to consider price, quantity, quality and of course, read some reviews and ask people for opinions. It is important to know the booster you have chosen to the smallest detail. Does it contain high-quality MMT? Is it suitable for my car? Those questions that you should ask yourself are important because you never know if an octane booster has the potential to ruin your paint job, for example. And no, that is not a joke, most of the octane boosters can do that if just a drop is spilled on your vehicle during the fill-up. The fact that an octane booster may or may not be street legal, is also really important.

If you already have bought an octane booster, figuring out the right mixture is the next step you should take. The first thing you need to do is pour the booster into the gas tank. Only after that should you add the fuel. Don’t forget to read the back of the bottle so that you would know exactly how much octane booster you need to pour. This way you will be sure that the booster and the gas will mix perfectly and you will reach the maximum potential.

Once you have poured the booster in the tank the only thing you need to do is add the regular gas. You just need to remember that your octane level consists of the octane number of the gas you are buying plus the octane number ups your level that the octane booster offers. So, hypothetically speaking if you are buying a 95 gas and you add a booster that increases it by 5, your level will be 100. If your car is more powerful and needs a higher octane level, you need to know that higher octane gas burns more slowly. That’s why your engine is less likely to knock.

You must use the booster within a year if you want to know what the best performance of the product is. If not, at least make sure that you store it in good conditions, such as its original container. Some boosters are light-sensitive, that’s why the original container is of such great importance. Not only that but also there are important instructions written on the back of the bottle so you shouldn’t throw it away!

Leaving the octane booster in your tank for long periods of time is not a good idea! When you buy a booster it is better if you use them as fast as you can. That is why larger containers are not always the best decision. They will save you money but if they are ethanol based and sit in your trunk, in time, they may cause you problems. Why ethanol? It’s simple- ethanol is not as efficient as other types of gasoline. It burns more slowly and therefore causes a slight decrease in power. Over time this may become even worse. So, our advice to you is to consider what you will need in the short term and buy only that amount.

Do Octane Boosters Really Work?

As we said by using Octane Boosters you will make your engine more powerful and help it run smoothly. However, if you are wondering if it really works or someone has already told you that it doesn’t, you need to ask your friend what type of car they drive.
If you have a modern car with turbo-charged engines, for example, you will most surely see some great improvements in the power of your engine. Cars built to run on 98+ octane fuel will have better performance and improvement in fuel consumption. So yes, Octane Boosters do work, if you have chosen the right one, and if your car is not a total wreck. Another thing that you have to do if you want your booster to work is to make sure that your vehicle is well maintained at all times.
It isn’t all bad news for you if, let’s say, you don’t have a sports car but you still want to try this. You just need to keep in mind that a lot of the boosters will not raise the octane levels by an adequate amount to be efficient. That’s why some people will say that using quality premium gas is a lot more useful to the performance of your engine.
You need to be careful with the type of booster you are buying. The typical small bottles you can find in auto parts stores or servos are a sham. They will probably not work and have no effect at all or they will clog the injectors and even damage the motor.

Benefits of Using Octane Boosters

To truly understand the benefits of this type of product you need to know how exactly does it work. The biggest benefit of octane boosters is the improvement of horsepower. This is possible because the liquid raises the compression ratio from the car. If your knowledge on this subject is not so impressive let us explain to you what does that mean. This is the amount of stroke that the cylinder in your vehicle makes before the fuel ignition. If we think about it carefully we can come to the conclusion that if the compression ratio that the engine needs are high, so is the required octane level. Now that the power of the octane booster is revealed you know exactly how they enhance your gasoline octane. In conclusion, we could say that the greatest benefit of using octane boosters is the fact that your car will be faster and your engine more powerful. You will also reduce emissions, save fuel and probably some money.

As many as the benefits are, there are also disadvantages. You should be really careful when you choose your product as it recently has been discovered that certain products on the market right now use several additives and chemicals that are not good for your car. Quite the opposite, they may even make your situation worse. So don’t be a scrooge, spend a few bucks more but stay untroubled with your car. Make a good investment!
