Best Fuel Injector Cleaner for Optimum Vehicle Performance

​Driving your own car makes you feel having the freedom to go anywhere you want and at any time you want. But along with owning a car is having the responsibility in taking care of it. In the case of fuel efficiency and engine performance, using the best fuel injector cleaner can make a huge difference for your vehicle.

What is a fuel injector?

A fuel injector is a valve that consists of a body that houses an electromagnetic coil and a sealing mechanism, which is kept closed by a spring. The injectors should either be fully open or fully closed. The amount of fuel that is injected determines how long the injector is open or how long the ball, disc, or pintle is removed from its seat.

This internal device is extremely important as soon as you start your vehicle up. When the fuel injector malfunctions, expect to experience several issues ranging from fast depletion of fuel to engine block noise and motor chatter.

One of the primary culprits in problems related to fuel injectors is cleanliness. No matter how oil companies promise clean fuel, there’s bound to be particulate matter than may get mixed into the fuel. Over time – and especially when the fuel line isn’t maintained – the particles may build up, thereby causing a lot of issues in your car engine.

The easiest way to address this particular issue problem is to use a fuel injector cleaner.

​What is a fuel injector cleaner?

A ​fuel injector cleaner is an additive that keeps fuel lines clean, protects the fuel injectors, and boosts fuel efficiency and mileage. When a fuel injector fluid is added to the fuel mix, particulate buildup in the fuel line and injectors will be dissolved.

Different factors may cause your fuel injectors to be clogged. Hydrocarbons and additives evaporate at different temperatures. Some amount of gasoline may be left behind the tip of the injectors each time the engine is turned off.

In addition, the volatile compound in the fuel may evaporate, leaving a residue on the injector tip. When it accumulates, it may start affecting the spray pattern and fuel distribution. As a result, the overall performance of the engine may be affected.

Choosing The Best Fuel Injector Cleaner

If you use your vehicle often, you need to check the fuel injectors from time to time as well.  A service may be required in the following instances:

  • Detonation which can lead to catastrophic engine failure
  • Failed emission
  • Increased fuel consumption
  • Poor performance
  • Pollution
  • Poor idle
  • Smoke from the tailpipe
  • Surging and bucking under light throttle

The quality of gasoline may sometimes be inconsistent. This may cause build-up, and lead to inefficient ignition and poor power output.

What could make it all worse is that the high output engines are sensitive to deposits that accumulate on fuel injectors, intake valves, intake ports, and in combustion chambers. With this, it can cause an increase in fuel consumption, poor performance, and increased exhaust emissions.

The easiest and fastest way to address these issues is to use the best fuel injector cleaner to keep your vehicle in tiptop condition.

A complete fuel system cleaner eliminates dirt and deposit from more than just the injectors. This should contain powerful ingredients and solvents to be able to thoroughly clean the whole system.

To be certain that you are purchasing the right fuel injector system for your vehicle, you need to look into the following factors:

Alcohol vs. polyetheramine (PEA)

Alcohol-based products are often used for old vehicles to get rid of years of deposits in the entire system. However, this is best performed by mechanics, and is already considered an obsolete practice.

For most modern running vehicles, polyetheramine will work as the best fuel injector cleaner component. This compound is a premium fuel additive known for its high fuel cleaning action on direct fuel injectors and fuel lines.

Strength

Some of the best fuel injector cleaner variants are strong enough to clean decades of solid buildup in fuel lines and injectors, while others are designed for milder approaches. Know first the status of your vehicle (i.e. if it has been in operation for quite a number of years already) before choosing a fuel injector cleaner based on strength.

New car models don’t need too strong compounds to clean the fuel injectors. Doing so may actually do more harm than good, as the strong components may affect the integrity of small moving parts inside your vehicle. In short, being too clean-conscious may end up damaging your car instead of maintaining it.

Price

Don’t be fooled by an expensive product, but don’t choose cheap ones instead. Focusing on price may not always lead you to the best fuel injector cleaner that your vehicle needs.

Having said that, ask around for a variety of the best fuel injector cleaner products in retail shops, and compare their features and prices. In the long run, you will be able to determine which fuel injector cleaner will fit best for your vehicle’s needs and your intended budget.

Frequency of use

Some fuel injector cleaners are designed for one-time use, while others need to be added each time you fuel up. These product types have varying price points, but try to estimate how much you’ll be spending with frequent usage comparing to a one-use product.

Engine suitability

Some of the most efficient fuel injector cleaners are not designed for diesel engine vehicles. Make sure to check for the compatibility of the product with your vehicle engine. Either ask the manufacturer or retailer about the product’s suitability for your car engine or do a quick online search for product specifications.

Using an incompatible fuel additive may create a lot of unwanted issues on your vehicle.

Enclosed instructions

Never buy a fuel injector cleaner that does not come with usage instructions. There’s a lot that you will probably miss out if you fail to follow instructions on how to properly use the product. Remember that while some of the best fuel injector cleaners are quite expensive, damaging your vehicle by not following usage directions will be more costly.

One significant detail that injector cleaners indicate in the label is the required fuel level before pouring the product in. Most products of this kind work optimally when you maintain a particular fuel level (as indicated by your vehicle’s fuel gauge).

Another important instruction has something to do with the right timing to start your vehicle. If you start up your car too soon, the product may not have slid down through the fuel line and injectors yet. Check the instruction manual for the recommended wait time before using your vehicle.
