Does camping propane expire or can you use it until it’s empty? If you’re preparing for a camping trip and find some propane from last year’s excursion, you may wonder if it’s safe to use. Will it still work, does it evaporate over time – and how do you know?

Camping propane does not expire. The tanks are designed to withstand high pressure, which keeps the contents stable over time. Camping propane does not evaporate or degrade. However, over time, the container itself may get damaged over time and leak.

Read on to learn how to check your propane tank for damage, store it correctly, and know when it’s time to replace your camping propane. 

Camping Propane Does Not Expire

Campers can store their propane tanks in a safe place and know they will be there when they need to use them for their next trip. It’s not necessary to replace camping propane unless you’re using the same tank you used last year. In this case, it’s just too hard to tell what might be left inside.

However, as long as you’ve got a backup, it’s fine to take that half-used tank with you. The propane doesn’t break down or evaporate, so you may as well use up what is left. 

Camp propane does not expire as long as it has been stored properly and hasn’t leaked, and you don’t see damage to the tank itself. 

Check Propane Tanks for Damage

If you use a camp stove or grill regularly, check to see if the tank is dented because this could indicate that there’s a leak. Holes in propane tanks can be patched with special tape but should never be used for cooking again. It’s important to replace all camping propane that’s been dented. Make sure you dispose of any propane tanks properly.

If you camp in cold weather, keep the propane tank inside your tent overnight to avoid freezing.

How Long Does Camping Propane Last? 

It depends on the size of the tank, how often it’s used and what type of device it’s used for. Running a small lantern will consume less fuel than cooking on a propane stove, for instance.

If maintained properly, a standard 20-pound camp stove tank can be expected to last up to two weeks, while a small, 16.4 oz tank will run camping appliances from 2 to 12 hours on average, depending on what you are fueling.

Camp propane is normally not in service for more than a few years before the tank itself needs replacing; however, this depends on how often it’s used and stored when not being used. 

How to Store Propane Tanks

You should always store camp propane tanks in a clean, dry place. 

If you own an RV and will not use your camping tank for more than three months, follow the manufacturer’s recharging instructions before storing it away since there is still some gas left inside camp propane, even if it feels empty. 

Storage Tips

Never store camp propane tanks in the basement or garage where temperatures can drop below freezing, which could cause liquid to move into the tank’s hose and regulator. 

It is also important to make sure campers are on level ground when they are being stored since camp propane tanks need a supply of oxygen at all times for proper use. 

If you are tent camping, camp propane tanks should be stored in a cool, dry place, such as your garage or an outside storage area. 

Where to Buy Camping Propane

If you camp frequently and would like to purchase camp propane tanks for convenience’s sake, check with local camping supply stores before buying them online since they may cost more than retail outlets. Since camp propane is combustible and dangerous, many online retailers don’t ship it. 

Why Won’t My Camping Propane Work with My Camp Stove?

If camp propane doesn’t light, you may just need to replace the camp stove’s regulator. If it still doesn’t work, perhaps camp propane is not compatible with your camp stove. You can find camp stove camp propane that is appropriate for your camp stove by checking your manufacturer’s specifications.

Can Camping Propane Freeze or Explode?

Camping propane is made from refined petroleum, which is why it doesn’t evaporate. 

Unlike gasoline or kerosene, propane doesn’t degrade. But it will freeze at -44 Fahrenheit/-42 Celsius. Camping propane isn’t very likely to explode in the summer heat, but is always better stored in a cool, dry place. 

It’s just a better idea to keep a pressurized container of fuel in the shade and in a cooler spot rather than expose it to blazing hot temperatures during a camping trip.  

Camping Propane Is More Likely to Run Out Than Expire

One of the most common questions campers have is, “Does camping propane expire?” The answer to this question depends on what you mean by “expire.” 

You may leave your camp stove outside in winter weather or use it frequently during the summer months. As long as there’s still some pressure left in the tank, then all should be good. If you have any doubts, bring along a spare!
