Quick Answer
Gasoline fungus in storage can cause a rotten egg smell, a cloudy or separated appearance, and a sticky or crusty sediment at the bottom of the container. Affected gasoline may also have a reduced octane rating, leading to engine problems. Prolonged exposure can render the fuel unusable.
Identifying Gasoline Fungus
Gasoline fungus, also known as phase separation or biogas formation, occurs when water and gasoline separate in a storage tank. This can be triggered by low temperatures, contamination, or poor storage practices. The affected gasoline will typically have a strong, unpleasant odor similar to rotten eggs, due to the release of hydrogen sulfide gas. Look for a cloudy or separated appearance, with a distinct layer of water or a sticky or crusty sediment at the bottom of the container.
Causes and Prevention
Gasoline fungus is often caused by contamination with water, bacteria, or other organic matter. To prevent phase separation, store gasoline in a clean, dry container with a tight-fitting lid, and keep it away from direct sunlight and heat sources. Regularly inspect the storage tank for signs of contamination or damage, and consider using a fuel stabilizer to prevent degradation of the gasoline over time. A minimum storage capacity of 25% capacity is recommended to prevent the fuel from freezing in cold temperatures.
Safe Handling and Disposal
If you suspect that your gasoline has been contaminated with fungus, do not use it for fuel. Instead, dispose of the affected gasoline in a sealed container at an approved hazardous waste facility. When handling contaminated gasoline, wear protective gear, including gloves, goggles, and a mask. Use a fuel siphon hose to transfer the affected gasoline to a storage container, taking care to avoid splashing or spilling the liquid.
