Dual-fuel and tri-fuel generators give you fuel flexibility no single-fuel unit can match — run on gasoline, propane, or natural gas and never get stranded when one source runs dry. Built for preppers, homeowners, and contractors who value uptime, these generators let you switch fuels for longer runtime and lower operating costs. When reliability through a long outage matters, options keep you running.
Dual-Fuel vs. Tri-Fuel
Both give you fuel choice; the difference is how many sources you can tap. More fuel options mean more ways to keep the power on.
- Dual-fuel: Runs on gasoline or propane for flexibility and easy storage.
- Tri-fuel: Adds natural gas for a continuous supply line at home.
- Runtime: Propane and natural gas extend operation without gas station runs.
Why Choose Fuel Flexibility?
- Uptime: Switch fuels when one source is unavailable during an emergency.
- Storage: Propane stores indefinitely without going stale like gasoline.
- Cost: Natural gas can lower operating cost where a line is available.
Frequently Asked Questions
What's the difference between dual-fuel and tri-fuel?
Dual-fuel runs on gasoline or propane, while tri-fuel adds natural gas so you can tap a continuous home supply line.
Why run propane or natural gas instead of gasoline?
Propane stores indefinitely and natural gas offers a continuous supply, both extending runtime without trips to the gas station.
Can I switch fuels while the generator runs?
Fuel selection is set before starting on most units — always follow the model's instructions, but switching between outages is quick and simple.
