How do I use fuel injector cleaner?

Adding the fuel injector cleaning fluid is pretty straightforward. When going to the gas station to fill up your tank, add the fuel injector cleaner first. Next, fill up your car with gas as you normally would. The gasoline and fuel additives will mix together and will help clean out your fuel system. How often you will need to use the cleaner will depend on the brand you are using, as some need to be used more frequently than others.

Pros and cons of fuel injector cleaner

The benefits of fuel additives being used to clean out your fuel system are plentiful. Fuel injector cleaners work to reduce carbon emissions, restore fuel economy and engine responsiveness, and extend the life of the vehicle.

The biggest drawback is that some automakers advise against using fuel additives as they can potentially damage O2 sensors, catalytic converters or other internal components. Using it more often than the product recommends can cause engine issues over time. Another flaw is that it can’t solve all of your fuel systems problems, if the car has serious issues that require a mechanic then a fuel injector cleaner won’t be much help.

What causes a dirty fuel injector?

Fuel injectors get dirty when old fuel and carbon build up and begin to clog the filters to the point fuel cannot flow through it. 

What are the signs of a dirty fuel injector?

There are many signs of dirty fuel injectors and you will need to act accordingly when you notice them. The check engine light may come on and the RPM needle may shake and move awkwardly, but there are other ways to know the condition of your fuel system. The most obvious signs are misfires, stalling and rough idling. Bad fuel economy is another sign you need to clean out your fuel system.

Do fuel injector cleaners work on motorcycles?

Yes, fuel injector cleaners can be used on motorcycles as long as the cleaner is suitable for gasoline engines.

Is fuel injector cleaner good for newer cars?

It can be a good idea for newer cars, but make sure you read your owner’s manual before putting anything in your fuel tank. On a newer car it can potentially prevent clogging and carbon buildup before it starts.
