When To Use A Dual Fuel Generator

A dual fuel generator: capable of running on either gasoline or propane—is one of the most versatile and reliable power solutions you can own, making it an invaluable asset for homeowners, campers, and emergency preppers alike. Deciding when to use which fuel generally comes down to a balance between convenience, availability, and storage longevity. Gasoline is typically the go to choice during immediate, short term power outages because it is widely available at local gas stations and offers high energy density, delivering robust power for heavy household loads. However, gasoline degrades quickly, often going bad within a few weeks to a few months. Gasoline can gum up a carburetor if left sitting in the tank. 

This is where propane steps in as the superior option for long-term emergencies or seasonal storage. Propane has an indefinite shelf life, burns much cleaner, drastically reducing maintenance issues and unpleasant exhaust odors. Propane also allows for an easy connection to large home standing tanks without the hassle and fire hazard of storing gas cans. Therefore, the ideal time to use a dual fuel generator is when you need ultimate flexibility. Use gasoline for quick, everyday convenience or immediate post storm needs and switch to propane for extended grid down scenarios or when preparing the unit for long-term storage.
