Every stove will have slightly different efficiency with some more fuel heavy than others. Some stoves allow you to invert the canister so that it is being fed liquid fuel, keeping it running strong without it having to vaporize perfect for use in low temperatures.
And as mentioned in the previous point, 'integrated' systems like the MSR WindBurner are really efficient, and a great way to minimise fuel use. You can also maximise all of your fuel by using it efficiently. Some stoves come with a boil and simmer setting, allowing you to turn down the flame and fuel use once you've reached boiling point.
In general, it's always a good idea to turn your stove temperature down a notch, whilst the performance difference will be negligible, over time the fuel consumption will go down noticeably. Whilst it was previously thought that altitude negatively impacted the performance of your stove, this is in fact partly wrong. Whilst you will usually find that at high altitude your canister performs worse than at sea level, this is due to the cooler temperatures rather than the altitude.
In fact, at altitude there is a lower outside pressure, meaning your canister will operate at a lower temperature as the pressure inside the canister does not have to be as great. However, the impact of cold temperatures usually outweighs this benefit, so generally, you will still need to take more fuel than you would at sea level. It is also worth noting that at higher altitude the boiling point of water decreases, so cooking times are increased.
To get you started, here is a rough guide. It is based upon one person, boiling water for an average amount of dehydrated food and drink. For winter, it includes the melting of snow. Measuring how much fuel you have left in a partially used canister is a really useful way to ensure you are not left short but equally, do not carry more than you might need.
There are two main methods for how you can measure how much fuel you have left in your canister, that's either through using scales or floating the canister in water. This is a quick and simple way of determining how much fuel you have left in a partially used canister. However, it is worth noting that as you need digital scales, it's a method to use when packing for your trip rather than whilst out in the field.
The first step is to measure the weight of an empty canister, making a note of the number. Simple boil-only meals are going to use a lot less fuel, while a multi-step gourmet meal will require more.
This is another consideration when planning your number of meals before the trip. As all these criteria change, so too does the way we approach our trip and ultimately the amount of fuel we need in the backcountry. Remember that every trip is unique and plan accordingly. Now that you have a general idea about your environment, conditions and group needs, consider your stove itself.
For instance, the Reactor Stove System boils a liter of water much faster and uses less fuel than the ultralight, minimalist PocketRocket stove. While MSR offers stoves built to meet the needs of virtually every backcountry user and scenario, there are a few constants when it comes to stove efficiency across the models.
Our fuel trip criteria offers a baseline to work from, but part of mastering fuel needs is experience, and a big piece of that process is trial and error. When Drew first started working at MSR in , he and a coworker embarked on a climbing trip with the then-new SuperFly stove and only one fuel canister he admits it may not have even been full for an overnight trip.
The pair ended up camping on snow and melting snow for water, using up more fuel than expected. The result? He considers the trip a learning experience and a valuable lesson for anyone traveling in the backcountry. Size Here at Primus, we carry 3. Time According to Eastern Slopes , an 8 ounce canister of fuel can burn for about three hours, when using a variety of heat settings. Winter Gas Shop Now. Fuel Bottles Shop Now.

Continue shopping Go to cart. That heat turns the incoming liquid fuel into gas. Most of these stoves burn several different kinds of fuel. More on that below. You fill the canister and determine, down to the ounce how much fuel you pack, making liquid fuel canisters more efficient for longer trips. Liquid fuel is easier to get your hands on—especially if you get a stove that can use multiple types of liquid fuel.
And liquid fuel is considerably cheaper. Priming a liquid-fuel stove can be tricky—and can create fireballs if done incorrectly. Make sure your stove can run on multiple types of fuel—the manufacturer should clearly note this—before putting anything but white gas in the canister.
Be careful when priming your stove. People tend to use too much fuel, which is a waste and can cause a large, dangerous fire. White gas: This is the best, cleanest-burning fuel you can put in your stove.
