Are the fuel savers sold online effective?

[Kiara]

They can save fuel, but the effect is minimal. Automotive fuel savers, as the name suggests, are devices applied to vehicles that aim to reduce fuel consumption or lower fuel usage through certain methods or means. Solid-state fuel catalysis and air oxygenation type: The product uses solid-state physical fuel and air catalysis (without powders or chemical liquids). During operation, its multiple functions can automatically clean the fuel lines and carbon deposits on the fuel injectors, optimizing the atomization effect of the injectors to ensure complete fuel combustion, thereby improving thermal efficiency. This results in enhanced power, environmental noise reduction, and genuine fuel-saving effects. Oxygen-enriched type: It utilizes the vehicle's DC power to ionize air at high voltage, producing O3, commonly known as ozone, which is then delivered into the engine to increase the oxygen supply.
