​A key difference between gasoline and propane fuel is the storage requirement of each. Gasoline breaks down faster than propane and so generally needs to be used within a year. Propane on the other hand can be stored for years. If you own a hybrid fuel generator you can use this to your advantage. By stocking up on propane tanks, you can protect yourself against future power outages. You will always have that propane fuel in case such an event occurs. In the short term, you can still the generator with gasoline for any other requirements. 

​If you live in an area where weather events cause power outages regularly, you are better protected with a generator that can use propane. The reason being, when the power goes out service stations no longer have the power they need to pump gasoline. This makes getting gasoline during a power outage very difficult. Propane on the other hand can still be purchased regardless of the power grid status. It can even be delivered to your house.
