To most of us, a car is an expensive but a worthy investment. It is every car owners wish that their car gives them maximum efficiency especially when it comes to maintenance and fuel consumption, putting into consideration that fuel is a must incur cost for every car owner.

Two months ago, my husband had to travel for some business conference and he therefore left me his car for the three weeks he was away. Within the first three days of using the car I noted that the car was not running efficiently as it was previously doing.

I took the car to our mechanic who after diagnosing the car recommended I buy a fuel system cleaner kit and he did a total fuel system clean up. To my surprise, I noted that after the exercise the car performance was back to normal and ran smoothly.

From my experience above, I think it’s therefore important for every car owner to know some few things about fuel system cleaner.

Below is some of the information you might find useful about the same.


What is a fuel system cleaner?

Fuel system cleaners are solvents added directly into the fuel tank to dissolve any build-up in the fuel injectors and fuel line. The solvents are then burned away with the fuel during the combustion process.

Importance of fuel system cleaners

The fuel that is pumped in our cars at the gas stations is not completely pure, it may contain additives and impurities. The fuel can also be compromised when in storage at the tank farms.

Sediments and chemicals in the fuel mean that deposits will certainly build up in the fuel system of your car over time. These deposits will decrease the fuel efficiency and limit the mileage of your car. If neglected for long, they can cause damage, which results to expensive repairs.

Adding the fuel system cleaners to the car fuel is like doing a detox to your car, which will give you noticeable improvement in how your car runs and how it consumes fuel.

Another important use of the fuel system cleaners is when storing your car for long periods. Leaving the car unused a long time increases the risk of sediments build up. It is therefore important to keep the fuel clean even when the vehicle is not in use preventing any damage or parts failure caused by dirty fuel after long storage.

How to use a fuel system cleaner

One follows three main steps when using the fuel system cleaners and you will easily treat your car and keep the fuel lines clean.

Make sure that the car fuel tank is almost empty. This will make you achieve a good mixture of the fuel and the cleaner.

Using your preferred fuel system cleaner, read all the instructions carefully and add the correct amount of the cleaner for the size of your fuel tank.

Empty the contents into the fuel filter on your car, and top up with your regular fuel.

For some particular cleaners there may be some other additional steps but for general maintenance, the above three steps is all you need with the majority of the cleaners available in the market.
