When To Use Fuel Injector Cleaner

Maintaining a car is no easy thing as various parts should be taken care of. Sometimes, the little parts that we ignore are the ones that cause major problems—for instance, fuel injectors. A dirty fuel injector is a common issue for most cars today. This is because most of the cars on the road are equipped with fuel injection systems that distribute fuel to the engine through electronically controlled fuel injectors.

Why do you need a fuel injector cleaner?

It is recommended to use a fuel injector cleaner after driving 5 thousand KM. The majority of fuel injectors are created to spray in an excellent and particular pattern that is crucial to the engine’s proper functioning. After a certain period of use, the nozzle that sprays the fuel may become dirty as a result of deposits found in the engine’s fuel. In case the fuel injector becomes extremely dirty or even clogged, it will no longer distribute fuel well. This will later negatively affect the engine’s performance and may lead to carbon emission issues.

How to use a Fuel injector cleaner?

First, you need to know the fuel storage capacity of your vehicle because the amount of fuel cleaner depends on the capacity of the fuel tank. Then buy an effective cleaner solution and read the instructions carefully, which can be found in the user manual. A single 15-Ounce bottle is ideal for a large vehicle. On the other hand,  a single ounce per ten gallons is enough for small vehicles like cars or SUVs. Empty your car tank properly to obtain a good mixture of cleaner and fuel. It is essential to mix the solution in the right ratio to achieve the best outcome. Remove the bottle cap and pour the recommended amount of fuel injector cleaner as instructed. Then refill it with normal car fuel, and the job is done. Your car engine will regain its lost power and gives you better mileage.

So, when you realize that your car has decreased in engine power & miles per gallon, rough idle, and personal cylinder misfires, then your fuel injector might be dirty and needs to be cleaned. At this juncture, you will need a fuel injector cleaner to clean the fuel injector for the effective and smooth performance of your car.

The dirt found in fuel injectors is usually from the fuel. Although manufacturers say that their fuel is pure, this is not true. Most of today’s fuel contains contaminants, and other by-products of combustion, carbon, and other dangerous deposits can form. When you have a dirty fuel injector, this may not be realized right away until you drive more than 5 000 kilometers.

To clean your fuel injector system effectively, you will need to acquire a quality fuel injection cleaner. There are various brands with different kinds of products. The cleaner that you buy should be able to excellently clean stubborn carbon and contaminants from the fuel system, injectors, and valves. In addition, it should restore horsepower and reliability. The moment it is cleaned, the fuel injector cleaner should protect the tank and other parts inside the injector for several miles.
