Quick Answer
Fuel degradation signs include reduced energy output, darker coloration, and visible sedimentation, often occurring after prolonged periods of storage and exposure to heat, moisture, and oxygen.
Identifying Fuel Degradation
Fuel degradation is a common issue in generator storage, particularly when stored for extended periods. Over time, fuel can break down due to chemical reactions with air, water, and other contaminants. One key indicator of fuel degradation is a darker coloration, often accompanied by a more pungent or sour smell. This is because the fuel’s hydrocarbons have begun to break down into lighter compounds, such as aldehydes and ketones.
Monitoring Fuel Degradation
To monitor fuel degradation, it’s essential to regularly inspect stored fuel for signs of contamination or spoilage. This can be done by visually inspecting the fuel’s color and clarity, as well as performing a smell test. A well-maintained fuel storage tank should have a clear, pale yellow or light brown color, with a mild, gasoline-like smell. If the fuel has become cloudy, dark, or has a strong, unpleasant odor, it’s likely degraded and should be replaced.
Storage and Maintenance Techniques
To minimize the risk of fuel degradation, generators and fuel storage tanks should be stored in a cool, dry location, protected from direct sunlight and potential sources of water. Regular maintenance, such as cleaning the fuel tank and replacing the fuel filter, can also help to prevent contamination and spoilage. In addition, using a fuel stabilizer can help to slow down the degradation process, allowing stored fuel to remain usable for longer periods.
