Does Propane Expire? Get the Facts About Propane’s Longevity and Reliability
Do you depend on propane to heat your home or fuel your appliances? Due to the seasonal nature of propane use, many homeowners question whether propane can “expire” or “go bad” over time. This common misconception can lead to concerns about the safety, efficiency, and longevity of stored propane and may leave you uncertain about the best practices for managing this energy source.
While propane users should be mindful of their home heating system’s maintenance and fuel tank expiration dates, we’ve addressed the top questions about propane storage, propane tank safety, and propane’s reliability in this blog. Keep reading to discover why propane is a long-lasting, safe, and efficient energy option for your home.
How long can you keep propane stored?
Many fuel sources, like gasoline and diesel, degrade over time, losing their effectiveness and efficiency. However, propane offers a significant advantage: when stored under safe and proper conditions, propane can be stored indefinitely without losing its potency. Unlike other fuels, propane does not expire or degrade over time, making it a reliable, long-term energy solution. While propane tanks don’t have an expiration date, it’s crucial to perform regular equipment inspections to maintain safety and efficiency.
Does propane dissipate in the tank?
Propane is stored as a liquid in your tank, expanding into a gas that fuels your appliances. During warmer weather, this evaporation process speeds up, converting propane to its gaseous form more quickly. For safe and efficient operation, it’s essential to fill the propane tank only to 80% capacity, leaving room for expansion and preventing over-pressurization. While propane transitions from liquid to gas, it won’t evaporate or leak as long as the tank remains securely sealed, ensuring you retain your fuel supply.
What happens if you use old propane?
While propane doesn’t expire, the idea of using “old propane” might raise concerns. Most propane users cycle through their fuel regularly, but for those who rely on propane primarily for heating in winter, you may wonder if propane that sat in the tank over the summer will still be safe and effective for the next heating season. Thanks to its stable chemical properties, propane retains its effectiveness indefinitely, no matter how long it’s been stored. Whether you use propane frequently or leave it in the tank for months, it will still burn efficiently and cleanly whenever needed.
Propane’s extended shelf life makes it an ideal fuel choice for rural homeowners seeking dependable, low-maintenance energy.
How do you tell if a propane tank is expired?
Knowing the age of your propane tank and understanding when it might be nearing the end of its safe lifespan is important. On the data plate, typically found near the top of the tank, you’ll find a date stamped in month-year format. This will tell you the date of manufacture. If you see a number like “05-18,” for example, this means your tank was manufactured in May 2018.
How long do propane tanks last?
Propane cylinders are good for 10 years, while larger tanks, like the ones that are used to heat your home or power your appliances, can last for 25 years. If it’s been more than 10 years since that date, it’s time to get your tank inspected by a professional.

How old can a propane tank be before it needs to be recertified?
When you decide to install a propane system in your rural home, one of the first steps will be a propane tank inspection. This initial inspection ensures that the tank is in good condition, that it has been manufactured according to the appropriate safety standards, and that it is fit for its purpose. Our trained professionals at Primemax Energy will check for any signs of damage or manufacturing defects that could compromise safety. They will also ensure that the tank is correctly situated for safe and efficient operation.
Following this initial installation and inspection, propane tanks must be reinspected every 5 years. Regular inspections allow for the early detection of any potential issues, such as corrosion, leaks, or damage to the pressure relief device.
When do propane cylinders need to be recertified?
Cylinders must be recertified and re-stamped every 10 years by a qualified gas technician. The manufacture date will be stamped on the collar.
