5 Best Fuel Injector Cleaners To Buy 2018 (And Why They Work)

When you own a vehicle, you always want it to be at its best. You invest a lot of time to keep it well maintained and even spend serious amount of money, upgrading it with special accessories, just to make it stand out from the others. However, many drivers are too much focused on the visual characteristics of their vehicles, not realizing that every part, especially the ones that are hidden under the hood, are extremely important. And these include the fuel injectors.

Fuel injectors are a crucial part of your car’s engine as they’re responsible for delivering the much needed fuel and keeping your car running at its best. Generally, fuel injectors are maintenance-free, but overtime, they can become dirty and clogged due to the tiny residues that are left behind as fuel flows through them. Clogged and dirty fuel injectors can cause your engine to run poorly, or even fail to run at all. Keeping them clean is a great way to avoid possible car issues and ensure your car engine performs at its peak capacity.

Fortunately, there are a number of fuel injector cleaners available on the market today. However, for those who are not mechanically-minded driver, it can be difficult to figure out which of the many options is worth buying. That’s why we’ve created this guide! Here, we give you our pick for the best fuel injector cleaners.

Fuel Injector Cleaner Benefits

Cleaning your fuel injector on a regular basis is an important part of proper vehicle maintenance. The main benefits of using the right fuel injector cleaner are the following:

  • Engine’s optimum performance. Fuel injector cleaners help remove contaminant buildup in your fuel system; thus, keep your fuel flow smooth and your engine’s performance at optimum level.
  • Extend the life of your fuel system. The best fuel injector cleaners not only keep your fuel system clean, but they also protect your fuel system by providing extra amount of lubrication and preventing further damage.
  • Save money on gas and maintenance. Having your own fuel injector cleaner means there’s no need for you to rush to an auto repair shop every time to get your fuel system cleaned, which can be very costly. For only a few dollars, you can do-it-yourself the cleaning process anytime you need it with the use of a fuel injector cleaner. And by cleaning it regularly, you can be assured that your gasoline will be used efficiently by your engine.
  • Less emissions. Clean fuel injectors guarantee exact delivery of fuel to the engines and ensure complete fuel combustion, resulting in less emission of toxic gases. This is not only great for your vehicle, but for the environment as well.

Fuel Injector Cleaner: How To Use

Contrary to what many believe, you don’t have to be a mechanical expert in order to clean your own fuel system. In just a few quick steps, you can keep your car clean and maintain it at its best.

  1. Choose your fuel injector cleaner and read the instructions.
  2. Make sure your gas tank is almost empty. If not, drive it first until it’s near empty. (This is to ensure that you get a good mix of fuel and cleaner.)
  3. Pour your chosen cleaner into your gas tank. Finally, fill up your tank with regular fuel. Your fuel system treatment will begin working immediately once you start driving.

Note: Keep in mind that not all fuel injector cleaners work for all types of engines. Choose the one that works best for your vehicle. Also remember that not all fuel injector cleaners are applied exactly in the same way. Some products require additional steps to make them work. That’s why you need to read directions carefully before using them. Improper use of these products can cause engine problems.
