BJ’s propane refill cost depends on whether a nearby club actually offers refilling or only sells tank exchanges; service and prices vary by location. Where refilling is available, a standard 20-pound grill tank commonly costs about $15-$25 to fill, while a tank exchange often runs $20-$30.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 20-pound tank refill | $15 | $20 | $25 | About 4.6 gallons at roughly $3.25-$5.45 per gallon |
| 20-pound tank exchange | $20 | $25 | $30 | Usually a swap for a filled tank, not a refill of the customer’s tank |
| New 20-pound tank | $45 | $60 | $80 | Tank purchase; filling or exchange may be an additional charge |
| Large-tank refill | $3.25 | $4.25 | $5.45 | Typical per-gallon range, where a refill service is available |
Estimates are general U.S. ranges, not a guaranteed BJ’s club price. Confirm service, current price, and tank requirements with the specific club.
What a BJ’s 20-pound propane tank refill may cost
For a standard grill cylinder, a reasonable budget for an actual refill is $15-$25. A typical 20-pound tank holds about 4.6 gallons when filled to the required safe limit, so a per-gallon rate of $3.25-$5.45 works out to roughly $15-$25 before any unusual fees. Local prices can fall outside this range, especially where transportation or retail competition differs.
First confirm that the club refills customer-owned tanks. BJ’s locations may offer tank exchange rather than an on-site refill, and availability can change by club. An exchange price is not the same as a refill rate: it pays for a ready-to-use cylinder and the exchange program, rather than propane measured into the customer’s own tank.
Many 20-pound cylinders are not completely empty when exchanged or refilled. A customer paying a per-gallon refill rate is charged for propane dispensed, not automatically for the tank’s full rated capacity. A scale-based transaction may also result in a different total than multiplying the posted price by 4.6 gallons.
Assumptions: standard 20-pound grill cylinder, ordinary access, no tank purchase, and no special delivery or service fee.
How propane, tank exchange, and service charges shape the bill
A propane quote can include more than the gas itself. If BJ’s offers a refill at the selected location, the main charge is normally the propane dispensed. A staffed filling station may have a minimum charge or payment procedure, but customers should ask rather than assume that a national chain uses one uniform policy.
| Quote item | Typical price | What it covers | When it applies |
|---|---|---|---|
| Propane refill | $3.25-$5.45 per gallon | Gas dispensed into an accepted cylinder | Where on-site refilling is offered |
| 20-pound exchange | $20-$30 per cylinder | Swap for a filled cylinder under the exchange program | Where exchange cages or service are available |
| Empty cylinder purchase | $45-$80 | New standard grill tank, usually before any fill | When the customer has no usable cylinder |
| Inspection or rejection | $0-$20 | Possible inspection, handling, or replacement-related expense | Depends on provider and tank condition |
| Local taxes | $0-$3 per transaction | Applicable sales or local taxes | Varies with jurisdiction and product |
The largest difference is often refill versus exchange, not a small service fee. An exchange can cost more than filling a partly used tank, but it may be convenient when the cylinder is empty, rusty, out of date, or not accepted for refilling. The customer should compare the posted exchange price with the estimated gallons needed and check whether the replacement tank is full to the exchange provider’s stated level.
Labor is generally bundled into a staffed refill price rather than billed as a separate hourly line item. If a vendor does quote a separate service charge, the calculation is ; a hypothetical 5-minute task at $60 per hour is about $5 in labor. That example is not a stated BJ’s fee.
Tank condition and propane gallons change the refill price
The amount dispensed is the most direct price driver. A tank that needs 2 gallons at $4.25 per gallon costs about $8.50 for propane, while one needing 4.6 gallons costs about $19.55. The final receipt may include tax or a minimum, and a provider may charge according to weight or metered volume under its own operating procedure.
Tank size is not the same as the number of gallons needed. A common “20-pound” grill cylinder is designed to hold about 20 pounds of propane, approximately 4.6 gallons, when filled to its safe limit. A nearly full cylinder costs less to top off than an empty one. Larger cylinders can require more gas and may not be accepted at a retail grill-tank station.
Condition and certification matter, too. A refill station can refuse a cylinder that is visibly damaged, leaking, badly corroded, missing required markings, or past its requalification date. A standard DOT cylinder typically has a 12-year initial qualification period from manufacture, followed by requalification rules that can depend on the method used. An exchange cage may accept some tanks a filling attendant will not refill.
Temperature and safe-fill procedures also affect the transaction. Propane expands as it warms, so cylinders are not normally filled to their full internal volume. A customer should not expect a 20-pound tank to take 20 pounds of propane every time; the remaining fuel, cylinder condition, and safe filling limit determine the amount added.
Example: 3.5 gallons dispensed at $4.25 per gallon equals $14.88 before taxes or any local charge.
Can a BJ’s club refill a customer-owned propane tank?
There is no dependable nationwide answer for every BJ’s location. Some retail locations sell propane through an exchange program, while on-site refilling requires appropriate equipment, staffing, and local approval. A club’s website listing or an exchange cage outside the building does not prove that staff will refill a customer’s cylinder.
Call the exact club before driving with a tank. Ask whether it refills customer-owned 20-pound cylinders or only exchanges them, what the current price is, and whether the station is open during the club’s full operating hours. Also confirm accepted tank sizes, payment methods, and whether the customer must bring an empty or nearly empty cylinder.
It is useful to ask whether the listed price is per gallon, per pound, or a flat exchange price. Ask whether the cylinder must have a current certification mark and whether the attendant checks the manufacture or requalification date. A short call can prevent a wasted trip, particularly when the tank is larger than a standard grill cylinder or has not been used for several years.
If a club offers only exchanges, check the tank markings and exchange terms before deciding. Exchange programs commonly provide a standard grill cylinder, but the exact fill amount, deposit rules, and ownership of the replacement cylinder can vary by program. Keep the receipt and follow the provider’s instructions for returning the cylinder later.
Refill, exchange, or buy a tank based on the real total
Refilling is usually the least expensive option when a customer owns a sound, accepted tank and needs a substantial amount of propane. At $4.25 per gallon, a nearly empty 20-pound cylinder needing 4.6 gallons costs about $19.55 before tax. A partly full tank can cost less because the customer pays for the amount added rather than a full exchange transaction.
Exchange can make sense when the existing cylinder is unusable or convenience matters more than the lowest gas price. At $20-$30, an exchange avoids finding a refill station and may replace a tank that a filling attendant would reject. The customer should inspect the replacement for visible damage and check the program’s fill representation rather than assuming every exchanged cylinder contains the same amount.
Buying a new tank is a separate decision. A new standard cylinder may cost $45-$80, with propane sometimes included and sometimes priced separately. A customer without a tank should compare a new-cylinder bundle with an exchange, because the cheapest initial purchase may not be the cheapest way to obtain both a usable container and fuel.
DIY filling from a larger cylinder is not a reliable cost-saving substitute for a proper filling station. Transfer equipment, cylinder compatibility, safe-fill limits, and fire-code rules matter. Using an unapproved method can create serious leak and overfill hazards, and it may void warranties or violate local requirements.
Three grill-tank budgets for common purchase situations
| Situation | Estimated calculation | Expected total | Price context |
|---|---|---|---|
| Top off a partly used tank | 2 gallons × $4.25 | $8.50-$12 | Before tax; possible minimum or local rate variation |
| Refill a nearly empty 20-pound tank | 4.6 gallons × $4.25 | $19.55-$25 | Assumes a refill station accepts the cylinder |
| Exchange an empty grill cylinder | One exchange transaction | $20-$30 | Price depends on local program and retailer |
These examples are budgeting illustrations, not BJ’s quotes. For a real comparison, use the posted per-gallon rate and estimate how many gallons the cylinder needs. An exchange is a flat transaction, so its cost does not decrease just because the returned tank still contains a small amount of propane, although program terms differ.
Suppose a customer’s tank needs 3 gallons. At $4.25 per gallon, the estimated refill is $12.75 before tax, which may be substantially below a $25 exchange. If the tank is empty, the refill estimate rises to about $19.55 at the same rate, narrowing the difference. Any minimum charge, inspection refusal, or trip cost can change which option is cheaper overall.
For a first-time buyer, include the cylinder itself. A $60 tank plus a $20 fill represents about $80 upfront, while an exchange may have a lower initial charge if the customer already has a qualifying cylinder to trade. Check whether the new tank is sold prefilled and whether the advertised price includes the cylinder, propane, tax, or exchange credit.
Regional propane rates and store availability vary
Retail propane prices are local. A refill station in a competitive suburban market may charge less than one in a remote area where delivery and storage are more expensive. As a practical budgeting allowance, rural or high-cost markets can run about 10%-25% above a low-cost local quote; nearby urban competition can sometimes place rates 5%-15% below a regional average. These are planning differences, not fixed BJ’s adjustments.
Availability can matter more than geography. A club that sells exchanges but does not refill has no per-gallon refill quote to compare. The nearest alternative may be a hardware store, farm-supply retailer, gas station, or propane dealer, each with its own operating hours and tank rules. Compare the cost of driving as well as the price displayed at the station.
Prices also move with wholesale propane costs, transportation, seasonal demand, and local taxes. Winter demand can raise costs in colder regions, while summer grilling demand can make retail tank service busier. A change of a few cents per gallon has limited effect on one grill tank: a $0.50-per-gallon difference changes a 4.6-gallon fill by about $2.30.
For a single cylinder, convenience and accepted tank condition can outweigh small per-gallon differences. For multiple tanks or frequent use, the per-gallon rate becomes more important. A customer should compare at least two nearby providers using the same tank size and the same service type: refill prices should not be compared directly with exchange prices without accounting for the different transaction.
Lower the propane bill by choosing the right service
Start by checking the tank’s contents and condition before paying for a full exchange. If the cylinder is accepted for refill and needs only a few gallons, a metered fill may cost less than a flat exchange. If it is damaged, out of date, or rejected by the station, avoid repeated trips and compare the cost of an exchange with purchasing a replacement cylinder.
Control the service choice before trying to cut small fees. Call BJ’s to verify the service, then compare its current refill or exchange price with nearby providers. Ask each provider the same questions about tank size, minimums, taxes, and inspection requirements. A low advertised per-gallon rate may not save money if there is a substantial minimum charge or a long drive.
Combine errands when practical, but do not store or transport a cylinder contrary to safety instructions. Keep it upright and secured during transport, close the valve, and avoid leaving it in a hot vehicle. These steps help prevent safety problems and the expense of replacing a cylinder damaged through improper handling.
For occasional grilling, a standard cylinder and a local refill or exchange may be the simplest budget. Frequent users can compare larger compatible cylinders and dealer pricing, but should confirm that the chosen retailer can fill that size. Do not pay extra for a larger container unless the intended station, storage arrangements, and appliance setup all support it.
