Top 7 Best Fuel Tank Cleaning Products

The time has came for you to clean your fuel tank, but you are not sure which are the best fuel tank cleaning products.

Having a clean fuel tank is very important if you want your vehicle to last long. A dirty fuel tank can do a lot of damage to the fuel system and to the engine itself.

Your fuel filter is doing a great job at cleaning the fuel before it is sent to the fuel lines and up to the engine, but there is no part of the vehicle that is designed to clean the fuel tank. That task is on you to do.

The fuel system is a closed system, but it still gets dirty. How? Well, when you open the fuel cap to add fuel, if you leave your fuel tank open long enough, dirt and dust will find their way in and will contaminate the fuel. The dirt will settle on the bottom of the fuel tank and will stay there for a long time.

Then, there is rust. Over time, the metal fuel tank will get rusty. There is nothing you can do to prevent it, only to cure it.

Here are the best products that you can use to clean your fuel tank.

Is a Fuel System Cleaning Necessary?

Depend. Fuel system cleaning is necessary only if you are experiencing car troubles associated with a clogged fuel system. The most common symptoms of a clogged fuel system are: Decreased acceleration, car jerks at idle, engine misfire, increased fuel consumption, and even your car not starting. Without the fuel, the car cannot run. If the fuel system is clogged, the engine won’t get the fuel needed in order to run, therefore, you will experience at least 3 of the symptoms above.

Do Fuel System Cleaners Work?

Yes, fuel system cleaners work. Not all of them, but the ones from the list above most certainly do. You don’t have to buy the most expensive one, just get the one with the most reviews on Amazon. even if you buy the wrong product, you won’t lose anything. You can always come back and order another fuel system cleaner.

How Often Should You Get a Fuel System Cleaning?

It depends on your car model. Most mechanics recommend that you clean your fuel system every 3 years or 45,000 miles. I mean, I would always first check the condition of the fuel filter. If it is all dirty and full of sludge, I would clean my fuel system with an additive. If your car is older and especially if you haven’t started it in years, I would most definitely clean the fuel tank with a rust remover before driving the car.
