Quick Answer
Using fuel stabilizer after fuel has gone bad is not recommended, as it may not effectively prevent or reverse the degradation process, and could potentially create other issues, such as clogged fuel systems.
Fuel Degradation Process
Fuel degradation is a complex process that occurs over time, especially when stored improperly. It involves changes in the fuel’s chemical composition, which can lead to the formation of gums, varnishes, and sediments that clog fuel systems and engines. When fuel has gone bad, the degradation process is likely already advanced, and adding fuel stabilizer may not effectively stop or reverse the damage.
Effectiveness of Fuel Stabilizer
Fuel stabilizers are designed to prevent fuel degradation, but they are most effective when added to fresh fuel, ideally before it’s stored for an extended period. If fuel has already gone bad, the stabilizer may not be able to counteract the existing degradation, and could potentially cause more harm. For instance, if the fuel has started to break down, adding a stabilizer could create a chemical reaction that further accelerates the degradation process.
Best Practices for Generator Storage
To prevent fuel degradation and ensure generator reliability, it’s essential to follow best practices for fuel storage. This includes storing fuel in a clean, dry, and well-ventilated area, away from direct sunlight and heat sources. Fuel should be used within 30 days of opening, and stored containers should be tightly sealed to prevent contamination and moisture ingress. If you won’t be using your generator for an extended period, consider draining the fuel tank and storing the generator with a fuel stabilizer specifically designed for long-term storage.
