Top 10 Best Fuel Injector Cleaners of 2019 – Reviews

People often consider how fuel efficient a car is upon purchase, regardless of whether they’re buying it used or brand new. One thing very few people consider, however, is whether the car will retain its fuel efficiency over time and whether they can do something to make that happen. It’s no secret that proper maintenance will not only maintain but even boost your car’s performance if done regularly.

We do realize that ‘maintenance’ in this context is a bit generic, so perhaps we should delve into the term a bit more. With a normal car, the first thing you want to properly maintain is the fuel injector. This is because the track that ensures the passage of fuel into the engine is directly responsible for your car’s fuel efficiency. In turn, this determines how many miles per gallon your car will require. Although you cannot go lower than the car’s factory specifications, you can still maintain its long-term efficiency this way.

That said, let us point out that there are many fuel injector cleaners out there and they each boast their own particularities. All cars require a little fuel injector cleaning every once in a while, so if you haven’t already, then you should definitely consider the purchase of one as a long-term investment more than anything else. To give you a helping hand in this regard, we put together a list of the ten best fuel injector cleaners the market has to offer at this point in time.

What To Look For In A Fuel Injector Cleaner

If you weren’t aware already, let us point out that you need to clean the fuel injector on a regular basis not only for maintenance purposes but also to help with your car’s fuel efficiency and all the costs that go with it. An unclean fuel injector can cause some serious blockage and potential leaks in the nozzle of the fuel injector, that may then result in the entire fuel line breaking down, thus rendering the car undrivable. You can avoid that by employing a fuel injector cleaner, of course, but as we are about to find out, they can differ quite a lot from one another. To ensure that you’re always getting the right quality, you should first learn about what characteristics make a good fuel injector cleaner and what to avoid when buying one.

Know Your Engine Characteristics

The first thing you have to keep in mind is that not every car is the same. Even though it might be the same model from the same manufacturer, the age of the vehicle, the engine condition, and the maintenance of the vehicle play a big part in its performance. That is why, before you purchase a fuel injector cleaner, understand what your engine needs. The biggest mistake people make is using a petrol cleaner in a diesel engine and vice versa. This can severely damage your engine. There are also special cleaners for sports cars, luxury sedans, supercars, and regular vehicles, so always know what you’re using before committing to a purchase.

Buying The Correct Amount

Purchasing fuel injector cleaners requires a little bit of thought as you don’t want to end up spending extra on cleaner you don’t require and nor do you want to save on small amounts and end up short. Understand the type of cleaning your engine requires and then buy a cleaner. You can purchase small bottles or a gallon of it for the first time before buying a larger dosage for roughly the same job. If you have to store your cleaner, make sure it is always kept away from flames, especially if you store large quantities at any given time.

How To Properly Clean Fuel Injectors

Read the instructions on the bottle before adding the cleaner to your fuel tank. Too much of it and your vehicle could malfunction; too little, on the other hand, would leave the engine dirty and underperforming. After adding the cleaner to your fuel, drive around for a while, don’t just expect it to spread throughout the fuel system by magic. This is another mistake people make. Instead of waiting for the cleaner to work, kickstart the process by using the vehicle. This pushes the cleaner inside and around the engine, which helps clean it quickly.

It is also important to remember that if you are using a single product from a manufacturer, do not mix another product into it. Even if your cleaner quantity falls short, purchase the same product rather than adding another one on top of it. This will not only cause quite a reaction when it gets in contact with the ingredients in the first cleaner but it will also most likely damage the engine and cause it to malfunction in one way or another.

When Is The Right Time To Use A Fuel Injector Cleaner?

This is a question best answered by paying close attention to your car and how it performs. While there is no definitive answer, it is best to use a cleaner if and when you feel your vehicle is underperforming. If you are not sure, you can always ask a professional for help. However, apart from a good understanding of your vehicle, you can also employ a series of vital steps to know for sure.

Don’t use it on new cars – Do not use a fuel injector cleaner in a brand new car. Doing this makes no practical sense as you will not only see little if any results as all the parts in a new car are already clean and functioning properly, but you may also cause irreparable damage to the fuel line. If your vehicle is already a couple of years old or has a lot of mileage on it, you would probably be right o presume that it is probably time for a cleaning. You can even tell that your vehicle needs a fuel injector cleaning when you notice a loss of power, unfamiliar engine noises, and/or sudden starts and stops.

Consider the climate – Vehicles in populated cities are prone to gathering more dirt than others which means they require regular cleaning. In this case, fuel injectors should be cleaned every year for a complete and thorough performance. Bear in mind that your car’s fuel line will also suffer more than usual if you live in an area prone to sudden changes in weather. In this respect, people who live in a temperate climate have to perform the cleaning process much more often.

Use it for storage purposes – If you plan on not using your vehicle for a long period of time, you might want to use a fuel injector cleaner to keep it up and running. This is because the collected dirt will have a negative impact on the stored fuel and will cause your vehicle to hesitate, stall, or even refuse to start when you finally want to start it up again. When the moment comes, use a cleaner before you start your vehicle so that whatever dirt was collected, can be filtered out and kept away from the engine, combustion chambers, fuel injectors, and other important parts.
