Best Fuel Injector Cleaner 2020

Fuel Injector Cleaner

We don’t have to be car aficionados to understand what a fuel injector is. As plain as it is, this piece is responsible for introducing fuel into the combustion chamber. Yes, that’s how important it is. It tells how efficient your fuel consumption is. It also tells how much speed you can squeeze out of your engine. The best fuel injector cleaner can help maintain excellent performance and prevent premature wear and tear damage to your engine.

These injectors are subject to a tremendous beating. Even before you had your car, the injectors went to the testing facility to have a beating for breaking it in and quality control.

Have you ever asked your fuel injector if they are fine? I bet no one does that! But when something is wrong with it, we can feel it in the performance of the engine. We would know when something is off. We know when the throttle does not respond well. We know if the idle is too rough.

The good thing is there are manufacturers of fuel injector cleaners that carefully studies and improves their formulation to help you get rid of gunk inside your engine and maintain the performance of the fuel injectors at pristine levels.

Fuel Injector Cleaners Buyer's Guide

Do Fuel Injector Cleaners Really Work?

First and foremost, it’s not enough that you’d look at the cleanliness of your car from an outside angle. The insides matter too.

Clogged fuel injectors can be a reason for diminished car performance, like poor acceleration, stalling, decreased gas mileage and high emission levels, so you can be sure that if any of these signs show up, your fuel injector needs some love.

These are valves that pressurize fuel and pump it through an aperture, releasing the fuel as a cone-shaped spray over the engine to help in attaining that full engine performance. Carbon and material deposits from the burning fuel soon build up in the injectors over time, the distance covered in its use, and the type of gasoline you expand on. When the clog comes about, you have to do one of two things: have the injector pulled out so that a machine can clean it (it’s thorough but at the same time, expensive), or use fuel injector cleaners.

To the skeptics, science can prove to you that these cleaners are genuine. The video states that these materials contain chemical polybutene amine (PBA) that contribute to the breakdown of bonds of carbon deposits trapped in the fuel injectors, which will then leave  the exhaust valves once they solubilize with the gasoline. 

A unique aspect of this substance is that it remains intact at high temperatures so it can do its work on the deposit breakdown unhindered. Isopropyl alcohol is also a key ingredient, as it helps prevent water mixed in the gasoline from freezing, and solubilizes it so it can harmlessly exit through the exhaust as well.

In addition to the above stated, more  there are cleaning solutions provided for your car. This includes lowering of engine emission, cleaning the combustion chambers, and reduce engine knocking and pinging (thanks to PBA and another chemical, the polyether amine or PEA). The Sulfur deposits are also removed from the gas gauge sensors so that a malfunction is prevented in that area.


Why You Need The Fuel Injector Cleaner

If your old man gave you old car, or if you bought a vintage car, there is a great chance you will be facing some engine issues. Any motorized vehicle is subject to wear and tear. So you will eventually need to have some form of a maintenance plan to keep your engine performance high.

It’s only recently that people are getting used to mixing fuel additives to unclog and clean fuel injectors and the fuel system. Old engines may have already accumulated years’ worth of carbon deposit that greatly affects performance.

Fuel additives can greatly enhance the performance of old cars and optimize the newer generations. Your usual fuel additive helps get rid of carbon deposits on pipes, valves, fuel injectors and combustion chambers.  Some are formulated to bind with water. Water mixed with fuel is a problem during winter as they tend to get frozen. Some additives are formulated to prevent water from freezing and facilitate its expulsion from the engine system to prevent it from causing rust.

Here are some of the benefits you can get from using fuel additives:

By eliminating deposits on the pipe and fuel injectors, the flow of fuel from the intake to the combustion chamber is optimized. The spray of the injector gets more accurate. This alone can snowball to other great benefits.

2. Optimal fuel combustion

When your injector introduces a consistent spray of atomized fuel, your engine will have a perfect rotation and makes sure that every small part works in perfect timing with all the other car components.

3. Better mileage

When your combustion chamber is burning the right amount of fuel in the right timing, the rotation of the engine becomes more efficient. This gives your automobile more power and more mileage with every drop of fuel you burn.

4. Smoother Idle

The perfect spray of your injector makes sure that every cycle of the piston gives the same power. The precise timing and rotation of the pistons make sure that your engine stays in place without unnecessary engine rock.

5. Better throttle response

Inevitably, when your engine is burning fuel with precise timing and equal power, every step on the throttle efficiently delivers more power and no delay.

6. Decrease carbon deposits and gunk in your engine

Using additives with concentrated detergents makes sure that there will be no buildup of carbon and gunk inside your engine that can potentially impair engine performance.


Factors to consider before making that valid cleaner purchase.

You’re probably enticed to get your hands on a fuel injector cleaner now, especially if you can see the symptoms of a clogged injector ruining the image of your beloved car. Still, you can’t just go out there without thinking things through. There are factors to consider before making that valid cleaner purchase.

The first is your car’s stability

Sometimes, a car may be too old and too worn down that no amount of liquid cleaner can help its case. Or, a car that is new and still decent won’t find any improvement with a cleaner because there is little to fix in the first place. The car owner has to be aware of his or her car specs and condition to know if a cleaner can or can’t be applied to it.

Second is finding the best cleaning solution

Technically, fuel injector cleaners are sold cheap and most of these products are safe to use, but inferior goods are often slipped into the market without being noticed by the common eye. As a result, you might find yourself victimized into buying a cleaner you thought would work well, but wouldn’t work at all despite the prints and selling points. To be on the safe side, the best cleaners you can buy are the premium ones. Apart from having their merchandise reviewed continually, they are the ones best trusted by the public and are more than willing to keep things that way.

Above list narrows down on the top-rated fuel injector cleaners, along with their perks and benefits. It’s highly suggestible to base from the list, but check to see if they both pin their fancy on a common product. It just goes to show that the two groups recognize that cleaning solution as exceptional.

If you already went your way into buying your preferred cleaner, you might as well get the cleaning started. The Video can give you a head start on how that’s done. 

Basically, you remove the gas cap from the car, then measure the appropriate amount of the fluid to be poured into the gas tank. It’s recommended to do this when the gas tank is nearly empty so that you can seamlessly pour the solution into the tank.

Afterward, fill the tank up with gas as you usually do. The two liquids will mix from that point and the cleaning process will be achieved. As for a time frame to keep yourself in check for when you are going to use the cleaning agent, it’s best to clean the fuel injector at least every 36 months, or 45,000 miles traveled.

All in all, fuel injector cleaners are a big help for a car to keep running and trouble-free. Using them will undoubtedly bring a better result in one’s car maintenance, but the utilization will still depend on the vehicle owner. It’ll all go down to whether or not the person is willing to spend on a small thing that’ll keep your car engines purring for more.  


How to Clean Fuel Injectors

The fuel injectors need to be cleaned from time to time. There is a surprisingly simple step-by-step process to use the fuel injector cleaner to clean the injectors.
