Fuel Injector Cleaners Engine Degreasers

When Clean Fuel Injectors Make a Difference

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.

Special Treatment for Diesel Cars

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.

A Universal Cleaner for Old and New Cars

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.

What Is a Fuel Injector Cleaner?

A fuel injection system is not necessarily the cornerstone of your average automobile but it is the part that no car can do without. You need to keep it clean. Otherwise, the harmful carbon, gum, and varnish deposits will always lead to hard starts, lost acceleration, and rough idling. The best fuel system cleaners will let you do just that.

Though relatively similar, different cleaners have different formulas and, as you would imagine, these formulas can differ too. The best solutions will be able to clean and lubricate carburettors and injectors, making the fuel burn more thoroughly. The right solution is able to clean the entire fuel injection system, including intake valves and combustion chambers.

Some cleaners can dissolve oil deposits in the crankcase. Certain products will be able to clean timing chain tensioners, VVT actuators, and quiet noisy lifters. Other than that, we would recommend the cleaners that can work with all forms of fuel injectors, including GDI.

Engine cleaners and tire shines do not necessarily work together with fuel injector cleaners, but they will let you improve your car's performance just as much, so consider looking into these products too.
