List Of The Top Costco Propane Tanks

That BBQ pit won’t fuel itself, especially if it has an empty propane tank connected to it. Maybe you’ve run out of propane or maybe you’re looking to stock up for the future.


funny bbq joke

Either way, you’ve come to the right place as we have a Costco propane tank list of our favorite ones that are available on the market today.

I know, silly, right?


No one wants to go cook outdoors just to find they have no propane, that is the absolute worst. 

Fun fact, the propane we use today wasn’t discovered until 1912, when Dr. Walter Snelling was conducting experiments for the U.S. Bureau of Mines.

The experiments involved several gasses that could be contained as liquids under the right conditions, one of these was propane.

And so, this was the birth of bottled propane.

Now go out and get a propane tank or at least take a second to check em out!

Our 2 Costco Favorites

We handpicked two splendid propane tanks from Costco, we feel these tanks are of the best and safest design.

Flame King 30-Pound Propane

This 30 lb. monster is complete with an OPD (Overfill Protection Device) valve and is made of steel.

This propane tank is the perfect size to use on your gas powered bbq.

With this specific tank you must fill it with LP gas, which it is absolutely ready to do as it is pre-purged.

The tank is covered in powdered coating, this protects the enamal of the paint on the tank so it does not oxidize from weather as quickly.

This tank does ship empty, so that is something to always keep in mind.

With this being a 30 lb. tank it is much easier to transport than larger propane tanks.

#2 - 100 lb Flame King Empty Steel Propane Cylinder with POL Valve

Flame King 100-Pound Propane

The 100 lb Flame King Empty Steel Propane Cylinder is equipped with a POL valve and a powder coated steel shell, perfect for durability and precision in use.

Propane tanks can be very dangerous if not stored properly, with this tank's slim and tall design it is almost impossible not to find a place in your boat, camper or even home for it.

This tank can also be used for bbq-ing or any other basic propane use, note this is a larger tank so it won't be as transportable as other propane tanks that are smaller.

Are propane tanks dangerous?

Yes and no, if not transported, handled or stored properly the tank may become explosive, while if you have proper propane tank fittings, transport, storage and handling you will not face many problems , if any at all.

What size tank should I take camping and what size for a BBQ?

When using propane tanks for camping you don't typically want a 30+ lb. propane tank to drag along, so we recommend using the smaller tanks 20 lb. and less for camping. Use 20 lb. and more for at home and BBQ use.

Why do propane tanks ship empty?

Propane tanks ship empty due to the hazard of propane gas being put under too much pressure or heat, if heated up in the tank or put under too much pressure the tank would combust.

How do you know when your propane tank is out of propane?

Usually, the propane tank will come with a gauge attached which is easy to read and will signify when your tank is running low. If this is not the case though, there are a few quick fixes you can employ to let you know approximately how much is left.

Running a cup full of warm water down the side of the tank and feeling for the cool spot is a nifty trick. The top of where you can feel the cool spot is the current fill level of the tank. Science!
You can estimate by the weight of the tank how much may be left, just lift it up and use your best estimations. This is by no means a foolproof method though.

You could also buy your own guage. These are inexpensive and easily attach to the gas line so that you never run out mid-cook again. 

When is it time to buy a new tank vs. refilling your old one?

There are pros and cons to both refilling and replacing your tank depending on the circumstances. If you are careful with maintaining the tank and checking for leaks yourself, then refilling can be cheaper provided there is a supplier in your area.

Replacement is often more convenient even though it costs a little more, you will rarely ever have to worry about maintenance issues. Additionally, if your tank has a leak or sustained some exterior damage, you should replace it immediately.

Buyers Guide - Factors to Consider

Handling and Transportation

Many propane tanks do ship empty due to the hazards associated with the transportation of propane gas. This and you will eventually run out of gas at some point, especially if you are using it for Barbecues during a busy summer. Either way, you will need to handle and transport the tank at some point. You should keep in mind that propane gas can be dangerous and be sure you are comfortable with managing the risk. Another thing to consider is that depending on tank choice, they can be heavy and awkward to maneuver.

For refilling, it is often possible to call a local supplier. You should make sure refilling can be easily done in your neighborhood before purchase.


This is a vital point to consider before making your purchase. As mentioned, propane gas can be extremely dangerous under the wrong conditions. Storage is a safe and dry place is one of these essential conditions which must be met. Making sure you have enough space in your garage to store the large tanks safely and with space left over is key. You want to ensure that the tanks have enough space to lay upright as intended to avoid potential leaks which can cause an explosion.

Weather Conditions

Weather conditions can also be tied in with storage to a certain extent. Especially if you live in an area of extreme hot or cold temperatures, it is of vital importance that you have a storage location which is spacious and out of any ferocious elements. This also includes heavy rain and strong winds, anything which can cause damage to the exterior or functioning of the tank.

Tank Size

The size of tank you want or need is something to consider based on a number of other parameters. These will likely include the space you have available for storage, ease of transportation, and how much you plan to use the tank.

Conclusion - Which One Should I Get?

Which tank you should choose will largely depend on the variable factors we have discussed.

More important than price is your ability to store the tank safely. If you have a large storage space and will use the tank regularly, you may want to opt for larger options.

Conversely, if you have limited space or live in an area prone to adverse weather, a small tank may be sufficient for your needs.
