What Is a Fuel Injector Cleaner?

Although fuel injectors have been around since the 50s, only the more recent modern car models have them by default. Fuel injectors help to maximize the performance of the car. When the car runs and the engine fuel i.e. diesel and gasoline run through the engine, carbon deposits are formed inside the fuel injectors and the car engine, causing poor fuel economy, loss of engine power and even may cause car engine breakdown.

A fuel injector cleaner is essentially a chemical liquid that is added periodically to the car fuel to remove the build-up and deposits from the fuel system of your car. It also helps to clean the fuel injectors and ensures that the car engine works efficiently. A fuel injector cleaner is usually added to the fuel once in a while; it helps to get the best fuel economy possible and also ensures that your car delivers the best performance. Using a fuel injector must be a part of your regular car maintenance routine.

Do You Need to Use a Fuel Injector Cleaner for Your Car?

Each time you fill fuel into your car, you introduce contaminants that can prevent the fuel injector from firing on all the cylinders. The cleaner, which is made up of high-tech formulae and special serums remove the build-up from the car’s gas that is left behind by impure fuels.

While some people are of the opinion that each time you refuel your vehicle, you should make use of a fuel injector cleaner, others feel that it should be used every time you change the oil, while some others feel that using a fuel injector cleaner is sufficient once a year. And, some people are of the firm opinion that these cleaners must not be used at all. However, choosing the middle path is the best.

Things to Consider Before Buying a Fuel Injector Cleaner

Choosing the right fuel injector cleaner may be a confusing decision. Before you actually go ahead and buy one, ensure that the fuel cleaner you decide to buy meets certain requirements.

Know Your Engine

When you buy a fuel injector cleaner for your car, you must buy one that is best-suited for your specific vehicle. For instance, a diesel fuel injector cleaner will not work properly on a car equipped with a petrol engine and vice versa and using them interchangeably can cause serious engine problems. Buy a cleaner according to the specification of your engine, fuel used and the usage of the engine. Engines of high-performance cars are more sensitive to injectors that are dirty as compared to regular cars. For example, in the case of a sports car, you have to ensure that the fuel injector is very clean when compared to your regular utility car.

Purchasing the Right Amount

There are various sizes and quantities of fuel injector cleaning fluids available in the market and you can buy either a small bottle of it or a gallon. The cleaner is flammable and when not in use, should be stored safely and kept out of reach of children. You could buy a small quantity that is just sufficient for one cleaning or for a few uses. If you opt to buy a large quantity though, ensure that you store it safely.

Look for Manufacturer Recommendations

Not every fuel injector cleaner is compatible with all types of car engines. So, it is a good idea to check the manufacturer’s suggestions before buying the cleaner. This way you can avoid any mistakes and get the best results. Before you buy and use a cleaner for your fuel injector, it is always a good idea to do some research.

Check Fluid Strength

Most of the modern cars have built-in catalytic converters, which are an integral part of the car’s exhaust system and these converters work with the fumes of the fuel. Sometimes, when the fuel fumes mix with the cleaner, it can cause damage and your car may display the “engine check” light. Although in most cases, this does not harm the catalytic converter; however, in the case that you make use of the wrong fluid or if the fluid is too strong, then the catalytic converter can get burned.

Cost Efficiency

The cleaner should not only do an effective job of cleaning, it should not be too expensive and be cost-effective, as you will be using the fluid often for as long as you have the car.
