How long does gasoline last in a generator?

Gasoline in a generator typically lasts about 30 days to 6 months before it begins to degrade. Over time, gasoline can absorb moisture and break down chemically, leading to reduced performance and possible starting problems. To ensure optimal performance, it is recommended to use gasoline within a few months of purchase or add fuel stabilizers, which may extend gasoline storage life.

For a backup generator, gasoline can be stored for up to 12 months if kept in a suitable container and under proper conditions. Using a fuel stabilizer can extend this period, helping to prevent gasoline from deteriorating. However, it is advisable to check and replace stored gasoline regularly to avoid possible generator performance problems in an emergency.

How long can I store gasoline in the emergency generator?

The operating time of a standby generator with a fuel tank depends on the size of the generator and the capacity of the fuel tank. On average, a small to medium sized generator with a 5 to 10 gallon tank can run for about 8 to 12 hours at half load. Larger generators with larger tanks can run for longer periods of time. Run time also varies depending on the load placed on the generator, with higher loads using fuel more quickly.

How long does an emergency generator run on one tank of fuel?

A generator can run as long as needed, provided there is sufficient fuel and proper maintenance is performed. Continuous operation must be managed carefully, considering factors such as fuel supply, cooling and regular maintenance to avoid overheating and ensure reliability. Most generators are designed for intermittent use, so prolonged operation may require additional considerations such as fueling schedules and maintenance checks.

Gasoline becomes unusable when it ages and deteriorates, usually after about 3 to 6 months without stabilization. Factors such as exposure to air, humidity and temperature fluctuations can cause gasoline to break down, resulting in the formation of gum and varnish that can clog the fuel system. Additionally, gasoline mixed with ethanol can absorb moisture, speeding up the degradation process. To prevent gasoline from becoming unusable, use stabilizers and store it in airtight, properly closed containers in a cool, dry place.
