There are various reasons for using fuel injector cleaners. Primarily, it is necessary for the cleaning and maintenance of your vehicle. Otherwise, your engine will go through issues, such as nozzle leaks, blocked fuel injectors, and non-closing or opening fuel injectors.

Among the culprits of unclean fuel injectors are rust, oil, and carbon. Without these elements, your car will obtain optimum gasoline consumption and better mileage.

To provide you an idea of this matter for creating a shortlist of products, given below are the types of fuel injection to treat:

1) Throttle Body Injection – This is considered the simplest or most basic type of fuel injector that your best fuel additive will be useful for; it aims to replace the carburetor with single or dual nozzles of the fuel injector. This type of fuel injector is considered the starting point for the development of other fuel injectors on the market with upgraded carburetor and systems.

2) Direct Injection – You may also need the best fuel treatment for this injector, which requires infusing fuel directly through the valves and into the combustion chambers. You will find it usually in diesel systems. This type of injection provides engineers better insight on cylinder combustion process.

3) Sequential Port Fuel Injection – This type is also known as sequential fuel injection, multi-port injection, or timed injection. It makes use of various injectors, which spray fuel in clusters or simultaneously. When the engine is idle, the fuel would be able to stay on the port for up to 150 milliseconds.

According to the engineers, this type of fuel injection activates the nozzles of injector separately. You will also find small upgrades on emission and efficiency of your car with this injection model.

4) Multi-Point Fuel Injection – It dedicates an individual injector nozzle to every cylinder. In this system, there is a better assurance that fuel vapor will be sprayed 100 percent into the cylinder. Conclusively, it has more accurate air and fuel ratio, design, and fuel intake prevention.

What to Look For When Buying

It is not sufficient to simply check the fuel injector cleaner reviews and select a product. There is a more concise way of choosing a cleaner, which includes assessing the right features or attributes a product should possess. To help you identify the best fuel cleaner for your vehicle’s injection system, given below are aspects to look for:

1) Compatibility – You should check the characteristics of your engine before buying a fuel injector cleaner. It is best to find a product that suits your car well. For instance, you would not be able to use petrol fuel injector cleaner in a diesel engine injector or this will result in tons of vehicle problems.

2) Budget Allocation – The best fuel injector cleaner reviews may not concentrate on the price of the products, but you should still consider how much you are willing to spend for the product. Generally, you will find the cleaners from $30 per gallon. The price of the cleaner will depend on various factors, such as the type of treatment, fuel, and driving habits.

3) Sufficient Amount – Do not simply buy a big bottle of the cleaner for the sake of storing it for future use.

Take note that even if you store the product, this will cause hazard given it is flammable.
