What is the purpose of a fuel stabilizer?

The purpose of a fuel stabilizer is to prevent fuel degradation and maintain engine performance. When fuel is stored for an extended period, it can break down due to factors like oxidation and evaporation, leading to the formation of varnish and sludge. This deterioration affects the combustibility of the fuel and can lead to starting issues or engine performance problems when the fuel is eventually used.

Fuel stabilizers are chemical compounds added to gasoline or diesel fuel to prolong its shelf life by slowing the chemical processes that cause fuel degradation. By doing this, they help ensure that the fuel remains viable for use over time, thereby supporting optimal engine performance, preventing clogs in fuel lines and injectors, and avoiding costly repairs associated with using stale fuel.
