Filling up your empty propane tank at Costco is a very simple process. First, locate the propane service station – it can often be found in the parking lot.

Then, reach out to one of the staff members that are currently working and they will assist you with anything you may need.

Do note that Costco attendants will not refill any propane tanks that have expired so do make sure to check that your propane tank is still in order before you head off to Costco.

Is It Cheaper To Buy A New Propane Tank Or Buy A New One?

Though buying a new propane tank when you run out might seem like the easier option, that can end up costing you quite a lot more in comparison to simply refilling your propane tank at Costco.

In many cases, refilling your propane tank will prove to be cheaper for the simple reason that you will only pay for the fuel rather than the fuel and the tank.

Aside from that, it is hard to tell when a propane tank is truly empty, meaning if you throw it away, you might be wasting propane that you have paid for and haven’t even used.
