Quick Answer
For a weekend backpacking trip, plan for 1-2 ounces of fuel per person per day, with an extra ounce for stove efficiency and cold weather. This translates to 2-4 ounces of fuel for a solo two-day trip. Stoves with high efficiency ratings can reduce fuel needs.
Understanding Stove Efficiency
When choosing a stove for your backpacking trip, look for models with high efficiency ratings. These stoves are designed to minimize fuel consumption while maintaining a reliable flame. For example, the MSR PocketRocket 2 has an efficiency rating of 4.2 oz/hour for boiling 1 liter of water, which is significantly lower than earlier models. This means you’ll need less fuel to cook your meals.
Calculating Fuel Needs
To calculate fuel needs for your trip, consider the following factors: the number of people, the duration of the trip, the type of stove, and the ambient temperature. In general, it’s a good idea to pack 10-15% more fuel than you think you’ll need, to account for unexpected delays or cold weather. This will ensure you have enough fuel to stay warm and nourished throughout your trip.
Preparing for Cold Weather
If you’re planning a backpacking trip in cold weather, you may need to adjust your fuel calculations accordingly. In temperatures below freezing, your stove will consume more fuel to maintain a reliable flame. As a general rule, add an extra ounce of fuel for every 10°F drop in temperature. This will help ensure you have enough fuel to stay warm and cook your meals even in the coldest conditions.
