✪ 5 Best Fuel Injector Cleaner Recommended By Experts 2017


Why should we use

the best fuel injector cleaner?

There was a time when manual vehicles still depended on a carburettor for proper combustion inside the engine. Nowadays however, in keeping with emissions laws, automobile companies have replaced the classic carburettor with a fuel injection system.

This modern technology in cars has been standardized in all new models released. Although a bit more complicated and expensive, it provides lesser emissions and more effective fuel usage.

Per cylinder, an electronic fuel injector is present meant to put stress on the fuel inside and then force it out through a tiny opening. The fine mist, a result of the fuel injector’s pressurized activity, combusts more quickly. In turn, it becomes crucial to keep fuel injectors clean to prevent any damage to the engine. Clogged and dirty injectors are more susceptible to unwanted emissions, misfire and engine problems.

There are is an endless variety of fuel injector cleaners available on the market, all with different components meant to unclog dirt and debris at the nozzle of the injector and all claiming to be the best at their field (You can check out the list of gasoline and diesel additives here).

Below are a few chosen products that could be well on their way as the best fuel injector cleaner.

5. Liqui Moly (2007-20PK) Jectron Gasoline Fuel Injection Cleaner - Cheap Prices

Not necessarily a full kit but rather a concentrated fuel injection cleaner, the Liqui Moly Jectron is packaged in 300mL (around 10oz) canisters in packs of 20. Meant to be used in conjunction with a cleaning kit like the MityvacMV5567 or the S.U.R. & R. FIC 203, the cleaner eliminates the debris build up within the fuel injectors. It is vital to use the best fuel injector cleaner in order to properly dissolve the cause of clogging which interferes with the spray width and thus, compromises the combustion.

With these types of cleaners, it is important to keep the engine running to instigate an ignition that will jump start the cleaning process. Usually, the fuel cap of the automobile is left ajar to prevent an internal explosion pushed by a jolt in pressure levels. The Liqui Moly Jectron’s canister comes with a nozzle that allows spill-proof and more accurate pouring.


The Jectron’s chemical makeup cleans the injector and its related parts; thus, providing a smoother idling, less hesitation and similar problems after the start up. Because there is a more efficient burning of gasoline, fuel consumption also lessens and emissions are much cleaner.

Users that attest Jectron as the best fuel injector cleaner in reviews suggest adding the cleaner at lower fuel levels (around 1/8th of the tank) then to keep the car running by driving around in order to allow for combustion to take place with the gasoline.

The reason behind this is to pour in higher levels of the cleaner to lower levels of fuel where the Jectron will be more effective in a higher concentration. As mentioned above, this should be done every few thousand miles or at least every six months for older models of cars whether internationally or locally made.

Simple classification of fuel injector cleaner

Diesel fuel injector cleaners

  • Despite the countless cleaners claiming to dredge fuel injectors of diesel automobiles, they are not normally needed on a constant basis. The reason behind this is that a diesel engine’s fuel injectors utilize very high pressure with levels up to 26,000psi, thus cleansing the interiors each time. It is more likely that injectors are worn out in diesel automobiles rather than clogged.


  • However, using petrol or very strong chemicals in the fuel injectors may do more harm than damage, stripping the lubricant in its interiors which can cause sediment build-up.

Petrol fuel injector cleaners

  • Evaporated fuel and detergent components from gas can create unwanted residue that can eventually block the nozzle of fuel injectors. It becomes imperative therefore, for automobile owners to find the best fuel injector cleaner both as maintenance and solution.
  • Petrol engines are more open to a variety of cleaning procedures. More commonly, additives are over-the-counter mixtures that you can pour directly into the fuel tank. These are used mostly every thousand miles on older vehicles for preventive maintenance while newer models only require at most a biannual cleaning.
  • A more aggressive and another best fuel tank injector cleaner is the induction method. The cleaner is introduced directly to the throttle or the fuel line which leads to the injectors. This means of unclogging concentrates directly on the fuel injectors. It is best to consult a fuel injector specialist with this method.

Advantages of Fuel Injector Cleaners

  • Fuel Injector Cleaners provides a DIY solution to dirty fuel injectors. Either as a tank additive or a direct flush, the best fuel injector should be able to strip clean the sediments off the injectors as well as the combustion chamber and intake valve.

Save your cash from pricey labor and learn to do the basics yourself.



  • Fuel Injector Cleaners provide preventive care for your automobile. Just as I mentioned above, older cars will need tune-ups with the help of the best fuel injector cleaner of your choice every a few thousand miles. Especially in petrol cars, a fuel injector cleansing will help the engine run more smoothly as well as eliminating vehicular emissions.


  • Fuel Injector Cleaning will increase fuel pressure. An uncluttered fuel injector will be able to maximize the pressurized fuel in its chamber, atomizing it for an effective burn. However, once the injectors are congested, the nozzle of the injectors does not atomize the fuel properly leading to an inefficient combustion. Lean misfires, rough idling and faulty start-ups are more likely to occur with dirty fuel injectors.
  • Fuel Injector Cleaning saves your engine from cheap gas. You had no choice and filled half of your tank with cheap, low-quality gasoline. But despite that mistake, your engine doesn’t need to suffer for your wrongs. Using the best fuel injector cleaner for your automobile can save you from the cheap additives in this kind of gas.

Low-quality gasoline has lower levels of detergent or replaced completely with a similar but less-effective additive.

Over time, these leftovers form into troublesome sediments that ultimately put your vehicle’s performance at risk. In my experience, the best fuel injector cleaner for cheap gas problems should include the additive, polyetheramine.

Fuel injectors need to be clean and cluttered to keep the spray width and pulse operating at its peak. By doing so, combustion is more efficient, emissions are cleaner and most especially, fuel consumption is lessened. Rather than taking apart your engine, try one of the best fuel injector cleaners mentioned above for either diesel or gasoline engines. It quickly and effectively cleans off the gathered sediments and dirt build-up within the chambers of the fuel injectors and its neighboring parts.

In conclusion, how’s about my own recommendation?

One simple sentence: “I will not hesitate to recommend S.U.R. & R. FIC203 Cleaning Kit as the best fuel system cleaner among all candidates above”. Using a separate cleaning kit that will never cause any damage to the inside of engine is always my preferred solution. That’s all I wanna say.
