Why Use an Injector Cleaner?

Injector cleaner is a solution that allows you to maintain your injectors in tip-top condition to increase their lifespan. This will save you money both in the short term with fuel savings, and in the long term because the cost of changing an injector is quite high.

Best Fuel Injector Cleaners

The main role of the injectors is to send as much fuel as possible to the cylinder. So, as they get dirtier, the performance of your vehicle gradually decreases. Hence the need to use an effective cleaner to maintain their performance and prevent the engine from being damaged.

Anyone who wants to keep their car in good condition should use an injector cleaner, and depending on your budget, you can do the cleaning yourself or hire a professional. Also, the price of the product is very reasonable, so there really is no reason not to make it part of your regular maintenance routine.

The Different Types of Injector Cleaners

There are several types of cleaners, and they all stand out for their performance and the type of car they are suitable for. These include:

Diesel injector cleaner

These clean the injectors, combustion chamber, valves, injection pumps, and pipes. They restore engine performance, eliminate black smoke from the exhaust, facilitate cold starting, and reduce excessive fuel consumption.

Petrol injector cleaner

These are designed to clean and protect the entire injection system. They reduce fuel consumption, prevent the seizure of injectors and pumps, reduce engine noise and wear, as well as lowering smoke and exhaust gases. They also restore the injector flow and regain the original performance of the engine.

How to Use an Injector Cleaner?

These products are simple to use and can be used in a variety of ways.


They can be used to protect the injectors from the accumulation of dirt. This is better suited to a new car to avoid performance problems due to the lack of maintenance of the injectors.

This normally involves pouring the cleaner into your tank with at least 20 liters of fuel. Then repeat the process every 5000 km.


This is more suitable for engines that have not been properly maintained for a while. In such cases, there could be a significant build-up of dirt, and they will, therefore, require a more concentrated cleaner.

Depending on the type of car and the problem – smoke, fouling, or loss of power, the frequency of treatment will vary as per the product’s instructions. In some cases, treatment can be carried out in one session with a dedicated product.
