The lifespan of a propane tank for grilling depends on tank size, grill BTU output, and cooking duration. A standard 20-pound propane tank lasts 18-20 hours on a medium-sized grill, but higher heat settings can shorten this time.
Propane Tank Lifespan Based on Size
💡 Tip: Cooking on high heat will reduce propane life faster than grilling on low or medium heat.
How to Check Propane Levels
✔ Weigh the Tank – A full 20-lb tank weighs about 37 lbs. Subtract the tare weight (empty weight) printed on the tank to estimate remaining propane.
✔ Use the Warm Water Test – Pour warm water down the side of the tank. The area where the metal feels cool is where the propane level is.
✔ Propane Gauges – Attach a propane tank gauge to get an exact reading.
Extending Propane Tank Life
✅ Use a Lower Heat Setting – Cooking on medium or low extends propane use.
✅ Keep the Lid Closed – Helps retain heat and reduces gas consumption.
✅ Regularly Maintain Your Grill – Clean burners for efficient fuel usage.
✅ Store Tanks Properly – Keep tanks in a cool, shaded area to prevent overpressure.

Turn off the grill, disconnect the empty tank, and replace or refill it before resuming cooking.
Final Thoughts
A 20-lb propane tank lasts 18-20 hours for grilling, but usage depends on heat settings and cooking duration. Checking levels regularly and using efficient grilling techniques can help extend propane life and ensure you never run out in the middle of a barbecue! 🔥🥩
