Propane Exchange vs Refill: Which Is the Better Deal?
If you own a gas grill, camp stove, or patio heater, you've faced this decision at the hardware store: swap your empty tank at the exchange cage out front, or drive to a refill station. Both get you propane. Only one gets you the most for your money. Here's the full breakdown.
How Propane Exchange Works
Propane exchange programs — operated by brands like Blue Rhino and AmeriGas — let you swap an empty cylinder for a pre-filled one. You hand over your empty tank, pay a flat fee, and walk out with a full-looking tank. It's fast, widely available, and requires no special equipment. You'll find exchange cages at Walmart, Home Depot, Lowe's, most grocery stores, and thousands of gas stations across Texas and New Mexico.
The catch? Exchange tanks are typically filled to only 15 lbs of propane, not the full 20-lb capacity your cylinder is rated for. The exchange companies charge a flat fee that often works out to $4.00–$5.50 per gallon — significantly more than what you'd pay at a refill station.
How Propane Refill Works
At a propane refill station, an attendant connects your tank to a bulk supply and fills it to its full rated capacity. You pay by the gallon for exactly what goes in. A standard 20-lb cylinder holds about 4.7 gallons of propane, and refill prices in Texas typically run $3.00–$4.50 per gallon.
Refill stations are found at dedicated propane dealers, some U-Haul locations, many RV dealerships, and select hardware stores. They take a few minutes longer than a swap, but the value difference is significant.
The Real Cost Comparison
| Option | Gas You Get | Typical Cost | Cost Per Gallon |
|---|---|---|---|
| Exchange (Blue Rhino / AmeriGas) | ~15 lbs (3.5 gal) | $24–$30 | $4.80–$5.50 |
| Refill (local dealer) | ~20 lbs (4.7 gal) | $14–$21 | $3.00–$4.50 |
On a per-gallon basis, refilling your tank can save you $1.00–$2.50 per gallon compared to exchange. Over a full grilling season — where many households go through 3–5 tanks — that adds up to $30–$60 in savings or more.
When Exchange Makes Sense
Despite the higher cost, exchange has a few legitimate advantages:
- Convenience: If you run out mid-cookout on a Sunday and there's a Blue Rhino cage at the gas station down the street, a refill station three miles away is irrelevant.
- Tank age: Propane cylinders must be recertified after 12 years. If your tank is old, rusted, or out of date, some refill stations may refuse to fill it. Exchange programs accept any cylinder in working condition and swap it for a newer one — effectively giving you a free tank upgrade.
- Availability: In rural areas or late at night, exchange cages are often the only option.
When Refill Is the Better Choice
Refill wins in almost every situation where a refill station is accessible:
- You get more gas for less money — a full 20 lbs instead of 15
- Your existing tank is in good shape and under 12 years old
- You use propane frequently and the savings compound over time
- You have a larger tank (40 lb, 100 lb) that exchange programs don't accept

The Bottom Line
