5 Best Fuel Injector Cleaners Reviews of 2023 in the UK (2023)

The Forte Specialist Injector cleaner is one of the best solutions for petrol engines out there. Based on distillates and combination of Stoddard and naphtha solvents, it provides sufficient protection to the fuel system while simultaneously prolonging the service life of your vehicle's engine.

Since the unleaded petrol decays over time, it can leave excess moisture as well as condensation in the fuel system. So, if your main concern is to get rid of additives that can harm the fuel intake system of your car, we can’t recommend Forte Specialist injector cleaner highly enough.

Highly effective, the cleaner deals with excessive acidity of the fuel you are using. Since petrol is never 100% pure, keeping the acidity levels as low as possible is crucial for the overall well-being of your car’s intake system, especially in the long run.

As to how to use this cleaning solution properly, it is recommended to apply the formula every 5000 km. Alternatively, if that is not an option, you can apply the cleaner to the injector after every oil change or simply pour 400 ml per 50 litres of fuel.

All things considered, the Forte Specialist is definitely one of the best fuel injector cleaner products available on the market today, thanks to its effectiveness, ease of application, and versatility.

Wynn's injector cleaning formula is designed with diesel-based injector cleaners in mind and will be a prime pick for owners of larger vehicles as well as smaller diesel cars.

Starting off, the kit comes with 3 bottles of cleaning solution in a box. Offering 325 ml each, they will be a decent option for vehicles that undergo frequent oil changes or that are extensively used. For better results, it is recommended to use the full bottle of treatment per every 4000 km. Alternatively, the cleaning formula can be used at every oil change to reduce the harmful effects of carbon, gum, or varnish residues in the fuel system and to remove them almost completely.

Apart from the fact that the solution has a strong odour to it, it is important to wear appropriate means of protection like gloves since the formula is corrosive enough to remove the residues from the fuel system and can definitely damage your skin if not used with caution. For added convenience, the shape of the bottle is designed in a way to help you with pouring the liquid directly into the fuel injector with little risk of spilling the contents.

To sum things up, this three-pack from Wynn’s proved to be an optimal solution for both smaller automobiles and bigger diesel engines that require additional maintenance. So, if your car suffers from injector-related issues, you might give this formula a try and the results might pleasantly surprise you.

The STP GST50400EN is a complete petrol fuel system cleaner that is designed to prolong the service life of your car. The name of the STP itself stands for scientifically-treated petroleum, which is not just words.

It is recommended to use the cleaner once per every 6500 km or every time you are about to change the oil in your car. Alternatively, if your car requires a significant performance boost, you can add about 400 ml of cleaner per every 50 l of petrol.

When used on a regular basis, the solution helps save up fuel (up to 3.2%), which is quite significant, especially in the long run. The decreased fuel consumption aside, the cleaner also helps in removing the build-ups from the intake valves that can be harmful to the engine of your automobile. This also includes the excessive fuel deposits of the injectors that occur in the intake system one way or another. Last but not least, thanks to the addition of polyetheramine (PEA), the cleaner formula can be used on both old and new car models.

In the end, if you are looking for a universal solution to all issues concerning the fuel system of your vehicle, then this fuel injector cleaner for petrol-powered cars will be an optimal choice.

The Hydra Power Blast is a fuel injector cleaner that can also act as a fuel stabiliser for your automobile.

First things first, let’s take a look at what you get when you opt for this cleaner kit. On top of the semi-transparent plastic bottle, the package is equipped with a handy injector straw that you can use to pour the solution into the fuel system of your car.

On top of its great cleaning capabilities, the solution can also act as a great octane booster for the whole fuel system which significantly improves the performance of your car.

Furthermore, the cleaner is optionally available in 500 ml, 1 l, and 5 l forms, in case 250 ml is just not enough for you. The effect of the Hydra Petrol Power Blast is as long-term as they come, unlike similar products that can be poured into your fueling system to improve the overall performance. While the best way to use the formula is to pour 50 ml of the treatment every 5000 km or so, it can be applied every time you change the oil in your car.

Wrapping things up, the Power Blast from Hydra is the best fuel injector cleaner for regular petrol engines. If you are looking for a good cleaning solution for your automobile to pass the emission tests without any major issues, this product will be right up your alley.

It’s all good when your vehicle runs on petrol, but what are your options when you have a diesel car? Surely, you can free yourself from the hassle and spend a lot of money on car service to clean the fuel injector. Or, alternatively, you can opt for an injector cleaner designed specifically for diesel vehicles.

For your convenience, this small 250 ml bottle from Hydra is equipped with a special dosing container on top, which will help you pour the amount of cleaner solution that will be just enough for your automobile. But if you think that is not enough, it comes together with a liquid hose that ensures that not a single drop will be lost when you pour it into your car’s fuel system.

Just like the Hydra petrol fuel cleaner, the version for diesel engines comes in 4 different bottle sizes, including 5 l, 1 l, 500 ml, and 250 ml, so you can optionally pick the one that suits your vehicle’s swept volume.

Designed to accommodate all diesel engines, the Diesel Power Blast from Hydra enables better stability of the fuel. This way, the solution helps reduce the fuel emissions that will inevitably occur throughout the service life of your vehicle.

Bottom line, the Diesel Power Blast is one of the top picks for you if you own a diesel car, motorcycle, boat, or an ATV of any kind. Reliable and easy to use, it makes all the difference when it comes to protecting the fuel system of your vehicle.
