For portable generators, you may need four to eight 20-lb propane tanks for 24 hours, while stationary generators will need larger tanks, typically 250 gallons or more.
Natural Gas Generators:
Natural gas generators are convenient for homes with existing natural gas lines, providing a continuous fuel supply. A 7-kilowatt natural gas generator consumes about 118 cubic feet of natural gas per hour, which equates to approximately 2.36 gallons of gasoline equivalent per hour. For 24 hours of use, you'll need around 56.64 gallons of gasoline equivalent.
Inverter Generators:
Inverter generators are typically smaller and more fuel-efficient, making them suitable for charging small devices like laptops or car batteries. They consume significantly less fuel than larger generators, but the exact amount will depend on the load and wattage requirements of your appliances.
To ensure you have enough fuel for 24 hours, it's recommended to store slightly more than the estimated amount, as factors such as weather conditions and load can impact fuel consumption. Additionally, consider using fuel stabilizers to maintain the quality of stored fuel and follow safety guidelines for storing and handling gasoline and other fuels.

Use a fuel stabiliser to prevent gumming
Fuel stabilisers are designed to prevent fuel from deteriorating over time. They are particularly useful for generators that are stored for 30 days or more. Fuel stabilisers prevent oxidation in fuel, extending its lifespan. They are also suitable for all kinds of gasoline and diesel engines, including two-stroke motors.
When adding a fuel stabiliser, it is important to ensure there is fresh gas in the tank, and that the tank is about 95% full. The optimal time to add a fuel stabiliser is when fuelling up. The stabiliser should then be poured into the tank, and the engine should be run for about 10 minutes to ensure the stabilised fuel is distributed throughout the fuel system.
Fuel stabilisers are typically made from petroleum products and bond with gasoline to prevent evaporation. They are a mixture of antioxidants and lubricants designed to repel water and limit evaporation. This prevents the formation of sticky resins that can damage carburetors.
It is recommended to treat the fuel at each fill-up to keep the fuel system clean and protected. However, it is not necessary to add a stabiliser every time the tank is topped off. A fuel stabiliser can preserve a full tank of fuel in a car or truck, and a small bottle can go a long way.

Store fuel in a cool, dry place
When storing fuel, it is important to keep it in a cool, dry place. This is because fuel deteriorates in storage and becomes gummy, which will plug fuel filters, foul injection systems, and prevent equipment from operating. An emergency is not a good time for your equipment to fail.
For example, gasoline stored in a cool, dry place in a properly sealed container can last up to a year. However, if you plan to store gasoline for longer than 30 days, you should use a fuel stabilizer to prevent the fuel from deteriorating. Fuel stabilizers can extend the shelf life of gasoline to two years or more.
If you are storing fuel for a generator, it is important to follow the manufacturer's recommendations. For example, Honda recommends leaving a full tank of gas in for storage of less than a year, with the carb drained. Additionally, you should run the generator every month or two to exercise it and ensure it is functioning properly.
When storing fuel, it is also important to consider the amount you need. In an emergency, you may need 12 to 20 gallons of gasoline to run a generator for 24 hours straight. However, it is recommended to only stock up on gasoline that you know you will use within 30 days. This could be 5 gallons, 2.5 gallons, or less depending on your needs.
