7 Best Fuel Injector Cleaners for 2019

  • Written by: William Copper

Today’s average fuel injector cleaner is made from natural, synthetic ingredients such as distillates, petroleum, and PEA (polyether amine). Some companies have decided to manufacture fuel injector cleaners that do not use PEA as an attempt to create safer, more effective products that are less abrasive. Although PEA is an effective ingredient for fuel injector cleaners, it often depends on the current condition of your fuel injector, engine, and vehicle. Techron, a fuel injector cleaner strongly based on Polyether Amines (PEA) was originally developed by Chevron and is very popular in today’s auto-parts market.

While there are alternatives to PEA such as PBA (polybutene amine), PEA proves to be a safer, neutral solution to improve both drive performance and the balance of fuel to methanol ratio. This helps to prevent engine failure or damage. Other products are made of naphtha or pale oil, which are also effective and serve as a natural, non-abrasive solution for cars that may need special attention or delicate ingredients.

Fuel Injector Cleaners: Who should use them?

As each vehicle will vary in condition, type of use, and fuel used (diesel for example), the necessity for different types of fuel injector cleaners should become understandable. Many consumers have found the products mentioned below to be effective at treating, restoring, and preventing carbon deposits, moisture, and varnish buildup in their vehicles. This includes many at-home maintenance vehicles from lawn mowers to snow blowers and even fuel powered generators. Because of flexibility to be used on various types of vehicles, it is evident that the technology of fuel injector cleaners has evolved substantially.

Vehicles that have been sitting for a long time or frequently driven in cold conditions will accumulate moisture build-up, dirt, and carbon deposits over time. This can cause clogging and destroy critical parts of both your engine and fuel injectors. Failure to start your vehicle due to a seized engine or clogged fuel line are all possibilities when a vehicle is not properly maintained.

How do Fuel Injector Cleaners Work?

The accumulation of moisture, carbon deposits, and sulfur in your fuel injectors will clog fuel lines, carburetors, injectors, combustion chambers, and your intake valves. Each of these parts is critical to the smooth, efficient operation of your vehicle which includes fuel economy (MPG). The chemicals and enzymes in fuel injector cleaners are designed to expel harmful, build-up from your vehicle in the exhaust system. Fuel injector cleaners use neutral, safe, and synthetic non-abrasive ingredients to do this, often made from similar ingredients and oils used in other common fuels and vehicles.

Failure to regularly clean and maintain both your fuel injectors and the engine can lead to vehicle performance issues, from poor acceleration to idling, throttle response and even stalling. Fuel injector cleaners that don't rely on ingredients like PEA or alcohol are usually made with natural, proven to work ingredients such as pale oil and naphtha. These ingredients are designed to naturally remove carbon, moisture, and sulfur build-up in a neutral way that won't harm your fuel injectors or engine.

Look at great explanation video:

What should I look for in a Fuel injector Cleaner?

When considering which fuel injector cleaner is right for you, look for the following product characteristics:

  • If you’re going to select a fuel injector cleaner that uses PEA (polyether amines) as its main ingredient then it’s critical you ensure it has at least 30%. Between 30-50% PEA is most desirable, and anything lower than this will likely be too diluted to have desirable effects.
  • For those who regularly drive in a cold climate, it’s important to select a fuel injector cleaner that is specifically designed with such for this. Some of these will be fuel injector cleaners that are made of synthetic, natural, or organic ingredients. Using these ingredients ensures the necessary fluidity for such tough climates.
  • Avoid fuel injector cleaners that contain or are known for promoting sulfur build-up. Most often those with alcohol can cause this, as well as some fuel injector cleaners made for diesel vehicles.
  • Select a fuel injector cleaner that is designed for not only cleaning your fuel injectors and restoring functionality, but also preventing future moisture, carbon, and debris builds up. Those that are listed as “conditioners” are desirable, as they provide an added sense of both security and restorative properties.
  • If possible, purchase a cleaner that increases compression while withstanding higher temperatures, as your engine gets very hot and this can cause wear or even damage in the long run of your fuel injectors and engine.
