How long does a 4 oz fuel canister last while camping in 2023?
A quick guide to working out how long a small canister will last while camping

Camping is a great way to get back in touch with nature and enjoy the outdoors.
It’s also a fun way to spend time with friends and family, or even make new ones.
But there are some things you should know before going out into the woods for an extended period of time.
One of these is how long your fuel will last when camping.
This article will cover what you need to know about how long your 4oz fuel canister will last when camping, as well as some other important information that you might want to consider before leaving on your excursion!
How long does a 4 oz fuel canister last?
When camping, a 4-ounce fuel canister will last for about three days if used consistently.
However, if you only use the stove for a little bit each day, the canister could last up to five days, and extremely frugally, 10 days.
As a very rough guide, a 4oz canister should last up to 1.5 hours in total.
It’s important to note that, obviously, the more you use the stove, the faster the canister will run out of fuel.
If you’re planning on cooking a large meal, it’s best to start with a full canister. This will ensure that you have enough fuel to complete the meal without running out.
How long will a 4 oz fuel canister last while backpacking?
However, if you’re looking to know how long a 4oz canister will last because you are going backpacking and want to keep your weight down, then you are unlikely to be cooking large and time-consuming meals.
If you only use your stove for a morning coffee and some noodles in the evening, you could very easily get 7 days out of a canister.
However, if you are worried about running out whilst on a trail where you won’t reach another shop for weeks at a time, we would recommend an 8oz canister.
And if your health and safety really depend on it, it is a worthwhile task to take your stove outside and test yourself before you use it on your trip.
On many trails, fire rings have now been removed so you can’t rely on using a campfire at night to cook meals.
Tips for getting the most cooking time out of your 4oz canister
- Place your stove somewhere where you are sheltered from wind. Wind greatly reduces the efficiency of your stove
- Use a windscreen around your stove if you have to cook in windy conditions
- If you are cooking food such as noodles or porridge, turn off the stove as soon as the water is almost boiling or begins to boil and allow the food to cook slowly in the heat of the water. It will take longer to cook but save lots of your gas
- Ensure your cookware has a tight-fitting lid to make water boil faster
- Don’t have the flame turned up too high. If there are flames licking up the side of your pan, you are wasting gas. Turn the flame down to as low as possible while still being able to boil or cook what you need to
In conclusion, the more heat your stove puts out, the faster a 4oz canister will run dry.
When camping in an area where you cannot rely on other methods of cooking food, it is best to purchase an 8 oz fuel canister so that you don’t find yourself running low at sunset and having to go without dinner.
It is also important to keep the flame turned down as much as possible so that gas isn’t wasted when boiling water or cooking noodles for example.

A windscreen can dramatically increase the amount of burn time you’ll get out of a 4oz gas canister. Even an almost unnoticeable 2mph wind can greatly reduce the efficiency of your stove.
