What You'll Learn
Fuel system cleaners can help remove harmful deposits
Fuel system cleaners are designed to remove harmful deposits from fuel injectors, intake valves, carburetors, and combustion chambers. These deposits, or contaminants, can accumulate in the bottom of the fuel tank, in the fuel lines, and around the fuel pressure regulator. The two main causes of deposit buildup in engines are ethanol, derived from plant material, and the fact that modern engines do not extract 100% of the energy from the fuel, leaving behind carbon deposits made from leftover fuel.
Fuel system cleaners use powerful detergents and solvents to dissolve fuel residue and carbon deposits, improving engine performance and fuel economy. They can also help stabilize gasoline and disperse moisture. Regular use of a good fuel system cleaner can improve vehicle performance and save money by reducing the need for repairs.
There are a variety of fuel system cleaners available on the market, with some products being more effective than others. For example, Berryman® B-12 Chemtool® High MileEdge Fuel System Cleaning Concentrate is a well-reviewed product that can be used in both 2-cycle and 4-cycle engines. It is added to the fuel at a ratio of 1 ounce of additive per gallon of fuel. Another recommended product is BG's 44K, which contains polyetheramine as its main component. It is suggested to be used every 5 tanks of gas, ensuring the tank is never less than half-full so that the cleaning process continues to work.
While fuel system cleaners can be effective, it is important to exercise caution and not overuse them. Some mechanics caution that the chemicals in fuel system cleaners that break up carbon deposits may also eat away at seals and gaskets, leading to leaks and other issues. Therefore, it is recommended to use fuel system cleaners at regular intervals, such as each time the oil is changed, rather than with every tank of fuel.
