Propane vs. Gasoline Generator for a Florida Hurricane
Most Florida hurricane backup generators are gasoline, but more households are switching to propane every year. Here's why propane usually wins for hurricane backup specifically — and the cases where gas might still make sense.

Key Takeaway
For Florida hurricane backup specifically, propane usually beats gasoline: propane stores indefinitely (gasoline degrades in 3–6 months even with stabilizer), burns cleaner, and is safer to store. Gas wins on upfront generator cost and fuel availability if you don't already have cylinders. Propane Refill Station in Hollywood, FL refills generator cylinders. Call (954) 966-1763.
Which is better for Florida hurricane backup: propane or gas?
For the hurricane backup use case specifically, propane usually wins. Here's the side-by-side:
Fuel shelf life: propane wins by a lot
Propane stores indefinitely in a sealed cylinder. A 20 lb tank you bought in 2026 will still work in 2036.
Gasoline degrades in 3–6 months even with a fuel stabilizer. Ethanol-blended gas (most pump gas) absorbs water from humid air, gums up carburetors, and causes generator starts to fail. Florida humidity makes this worse.
This matters because most hurricane backup generators sit unused for 11+ months a year. With gas, you have to drain and refill annually. With propane, you swap the cylinder when you use it.
Storage safety: propane wins
Propane in sealed DOT cylinders is safer to store than gallons of gasoline. Cylinders are pressure-rated, valves close tight, and propane doesn't evaporate or leak vapor as easily as gasoline. Gasoline cans (especially old or worn ones) can off-gas, attract sparks, and pose fire risk in a hot garage.
Engine cleanliness: propane wins
Propane burns cleaner than gasoline. Less carbon buildup means less generator maintenance, fewer carburetor problems, and a longer engine life. This matters most for a generator that mostly sits idle.
Generator cost: gas wins (slightly)
Gas-only generators are typically a bit cheaper than propane-only or dual-fuel models. The gap has narrowed in recent years — most popular hurricane-backup generators are now dual-fuel (propane + gas), so you can pick depending on what's available.
Fuel availability after a storm: it depends
Both fuels get scarce after a major hurricane. Gas stations have lines, run out, and many are without power to pump. Propane refill stations and exchange cages also see lines but tanks store at home, so if you stocked up properly, you don't need to refill mid-outage.
Edge: if you stocked propane cylinders before the storm, propane wins because you don't have to leave the house. If you didn't stock anything, gasoline might be slightly easier to find at a still-operating station.
When does gas still make sense?
- You already own a gas-only generator and don't want to buy a new one
- You actively use the generator (worksite, camping, RV) and rotate fresh gas regularly
- You don't have safe outdoor space to store propane cylinders

Frequently Asked Questions
Is a propane or gas generator better for Florida hurricane backup?
Propane usually wins. It stores indefinitely (gas degrades in 3–6 months even with stabilizer), burns cleaner, and is safer to store. Gas wins on upfront cost and on convenience if you actively use the generator and rotate fuel.
How long can I store propane vs gasoline for hurricane backup?
Propane stores indefinitely in a sealed cylinder. Gasoline degrades in 3–6 months even with stabilizer, and Florida humidity makes ethanol-blended gas absorb water and gum up carburetors.
Should I get a dual-fuel propane/gas generator?
Yes if you want flexibility. Most popular hurricane backup generators are now dual-fuel. Lets you use propane for storage and switch to gas if needed.
Is propane safer to store than gasoline?
Yes. DOT propane cylinders are pressure-rated and sealed. Gasoline in cans can off-gas, absorb moisture, and pose fire risk in hot Florida garages.
Does propane burn cleaner than gasoline in a generator?
Yes. Propane produces less carbon buildup, fewer carburetor problems, and longer engine life. This matters most for generators that mostly sit idle (the typical hurricane backup use case).
