How Much To Fill Propane Tank For Grill

How Much To Fill Propane Tank For Grill

How Much To Fill Propane Tank For Grill? Professionals would advocate having your propane tank filled by a local provider over a tank exchange at a gas station or large box shop in terms of getting the most bang for your buck. The major businesses frequently use only 15 pounds of propane in their BBQ tanks. This implies you’ll only get 3.5 gallons of propane (15 pounds of propane Equals 3.5 gallons of propane). Normally, your propane tank is filled with 20 lbs of propane (4.7 gallons) from your local garden shop or gas marketer.

During summer time it is an ideal opportunity to break out the barbecue, give it a careful cleaning, slap a few patties on it, and have your first lawn picnic of the year. But, how do you check the propane level of a gas grill? Most propane tanks don’t go with a measure to tell you how much fuel is remaining. Also, you most likely don’t have any desire to run out and need to make an excursion to the store while you are busy cooking.

Luckily, there are a couple of approaches to take a look at the degree of propane before starting up the barbecue. 

Whenever you have your propane topped up, you can figure out how to barbecue more intelligently by reading the information provided in this article.

With Heated Water To Check Propane Level Of A Gas Grill

One of the speediest ways of approximating the fill level of a propane tank comes from heated water. All you want is a touch of high temperature water.

  • Fill a cup or a little pail with boiling water from the tap.
  • Pour the water down the side of the tank.
  • Run your hand over the side of the tank and feel for a cool spot.

The highest point of the cool spot is the fill level of the tank. What’s going on here is the fluid propane inside the tank is engrossing the hotness from the water, which makes the metal mass of the tank cool to the touch, though the tank divider over the fill line will be warm.

Some may wonder what the big problem is because the difference is only 1.2 gallons. However, 1.2 gallons of propane means around four to five hours of more cooking time for grilling. I could show you the math, but it would be boring, even Steven Hawking.

Furthermore, the cost of a tank at one of these swaps is generally $20-22. Many local propane marketers offer tank swap rates throughout the summer months if you hunt around. The price of a bottle exchange usually ranges from $12 to $15.

The per-gallon comparison is as follows:

A $22 tank swap at a Big Box Store equals $6.28 per gallon of propane.

For $12, you get $2.55 per gallon of propane from a local fill station.

When Should You Refill Your Tank To Fill Propane Tank For Grill

The simplest way to figure out when your tank needs to be refilled is to weigh it. The main difference between the Tare Weight and the remaining propane is the quantity of propane.

For example, TW=17, the tank’s total weight is 25 lbs. This indicates you have 8 lbs (25 lbs – 7 lbs = 8 lbs) or 1.9 gallons of propane remaining. It’s worth noting that 1.9 gallons equal around 7 hours of grilling time.

Having a backup tank and just swapping it out is the best choice. They will charge you a flat rate rather than a per-gallon fee if you bring a half-full tank to be filled. As a result, it’s also preferable to run out and then get it filled. You can attain this with the help of a backup tank.

The Benefits Of Putting Your Propane Tank Underground

  • You are in a condition that is prone to harsh weather, particularly deep cold. When the tank is underground, it is surrounded by earth, which helps to maintain a consistent temperature.
  • When it comes to potential damages such as propane leaks, underground propane tanks are safer because a gas leak would be contained better by the earth. Propane is non-toxic to both people and the environment, although flammable.
  • You’d want it to be hidden. You can use landscaping to surround an underground tank’s top, which houses the gauges and other controls. An underground tank may sometimes increase the value of a home.

Propane Tanks: Everything You Need To Know To Fill Propane Tank For Grill

  1. Full – For those new to propane, it’s worth noting that you will only fill any tank to roughly 80% capacity. As a result, a 100-gallon tank will only be 80 gallons full. This safety measure allows for the gas to expand as it warms. An overfill prevention mechanism is included with new tanks.
  2. Propane tank recertification – Any cylinder weighing less than 100 pounds must be recertified twelve years after being manufactured and then every five years after that.
  3. Local construction codes — You must set back underground tanks at least 10 feet from any road, building, or property line.
  4. Longer engine life — According to the US Department of Energy, “one reason for propane’s appeal for use in light- and medium-duty vehicles, such as trucks and taxis, and heavy-duty vehicles, such as school buses, is the potential for cheaper maintenance costs.” Propane’s low carbon and low oil pollution properties may help engines last longer.”
  5. Issues with cold starts – “Propane operates effectively in cold weather conditions because the fuel combination (propane and air) is entirely gaseous.” Because of this, propane-powered cars avoid many of the cold-start concerns that come with liquid fuels.”
  6. Alternative fuel – Propane is a vehicle fuel that you may use in place of gasoline.


Propane costs vary seasonally, so it’s best to replenish your propane supply in the spring. The charges per gallon will vary depending on the size of your tank. You have the choice of exchanging the tank or having it filled at home for a cost that is normally factored into the per-gallon pricing.

One important aspect to remember is never running out of petrol because emergency gas replacements are typically much more expensive.
