Read out this complete guide to know how long do propane tanks last for grills. Propane tanks would usually last for 18-20 hours if you are grilling on a medium-sized grill. Similarly, if you are using a larger grill, they can burn as much as 20 pounds of propane in 10 hours or less.
Usually, you would be using 1-2 pounds of fuel per meal if you are using the medium-sized grill on high heat.
Propane tanks are used for cooking, heating, and barbecuing. They are typically filled from the valve near the top of the tank and can be refilled by opening the valve at the bottom of the tank and pouring in fuel until it is full.
Common Sizes of Propane Tanks
Propane gas, also known as liquefied petroleum gas (LPG), is a cryogenic liquid hydrocarbon that is commonly used for cooking and other purposes.
Tank sizes are categorized by types of cylinders, with the most common size being the 5-pound cylinder. The other three tanks are designated by their weight in pounds: 10 pounds, 20 pounds, and 40 pounds.
However, a propane tank cannot weigh more than 40 pounds. The most common size of the propane tank is the 20-pound propane tank, which is the standard size for a camp stove.
So How Long Does a 20LB Propane Tank Last on a Grill?

When considering the most commonly used sizes, the propane tank would last anywhere between 18 to 20 hours on a grill. As mentioned before, a larger grill would last for a lesser duration.
What Should I Look for When Choosing a Propane Tank?
Propane tanks are a common fuel for portable stoves and other cooking devices. When choosing a propane tank, you should consider:
- The size of the tank
- Whether it is a sealed or an open system
- How much fuel it can hold?
- How many hours of runtime does it offer?
It’s also important to know whether you will be using the propane tank in conjunction with other appliances that require gas like your oven or refrigerator.
There are some more factors to consider when purchasing a propane tank, for example, weight limit, length of time before refueling is required, and type of regulator it supports.

How Long Do Propane Tanks Last for Grills?
For grills that are to be used regularly, it’s important to know the lifespan of the propane tank. This helps you decide whether it makes sense to buy a new one or get a new grill and avoid buying another propane gas tank in the long run.
It can depend on how often you grill and your grilling style. If maintained properly, the life span of propane tanks could be as high as 5 years.
Quick Maintenance Checklist For Propane Tanks

A propane tank delivers high-pressure, high-temperature, fuel gas that powers appliances in your home or workplace. You should take care of your tank with this checklist.
- Check the propane tank for leaks. If the leak is located, repair or replace the regulator
- Replace cracked or broken tanks.
- Periodically check pressure relief valve settings; adjust if necessary.
- Check the pressure relief valve to ensure the integrity of the installation. Check to see if the system has been recently serviced and that the shutoff valves are properly adjusted and in good condition.
- Routinely check the liquid level and make sure it stays within the proper range (2/3 full).
- Retighten shutoff valves regularly; over time they can become loose due to expansion and contraction of the system with temperature changes, movement, etc.
What Are the Benefits of Using Propane Tanks for Grills?
Propane gas is one of the most commonly used fuels that replace traditional cooking fuels like charcoal and wood.
It is popular because propane gas has low carbon monoxide emissions that are also heat-resistant at high temperatures, it is widely available, highly volatile, and easy to transport using a tank.
They are also cost-efficient fuels in the world and are commonly found in grills. Other important benefits include:
- can be stored easily
- Doesn’t emit fumes harmful to plants, pets, or humans
- Doesn’t require fuel additives that can be dangerous
- Propane gas burns so cleanly that you don’t need a charcoal chimney starter
- Has a high heat-producing potential because it is a liquid that vaporizes at a low temperature, producing heat as a result.
How to Safely Store Your Propane Tanks?
Propane tanks are usually stored in the house or garage where they can be kept safe from any damage and harm. However, some people have found it difficult to store them in their houses because of their lack of space.
This is when they opt for an indoor propane tank storage unit. These units are perfect solutions for those who don’t have enough space or need to store multiple tanks at once. They should also be stored away from extreme temperatures as this could cause harm to the stored gas.
An indoor propane tank storage unit is a device that allows you to store your tanks indoors so you don’t have to worry about any harm coming to the gas inside of them. They are usually made of durable materials such as aluminum and stainless steel, and they have wheels on the bottom so that they can easily be moved or rolled around. These devices come in different sizes, but they are usually between 4-8 feet tall and wide.
Concluding Remarks
There are three types of propane gas tanks that you can buy: liquid, pressurized, and direct-injected tanks. Each type has its own unique set of features and uses.
To figure out which one is right for you, consider what the grill you plan to use it with requires, such as cooking temperature and fuel capacity.
