Primus has gas for all seasons and purposes. We offer three different gas mixtures for different conditions: Summer Gas, Power Gas and Winter Gas, in order to optimize the energy and effectiveness when and where you need it.
Power Gas is our most versatile blend, delivering excellent power even around zero degrees Celsius. Summer Gas is optimized for maximum fuel efficiency in hot conditions up to temperatures to 40 ° C. For cold temperatures, we have created Winter Gas that works effectively down to -22 ° C.
Our multifuel stoves can run on several different fuels, from gas to kerosene and when needs must in an emergency – even aviation fuel (our OmniFuel and OmniLite Ti even run on diesel if required). However, the fuel that is most suitable depends on more than one factor, and depending on where in the world you find yourself, you may find certain types of fuel difficult to get hold of.
We list the most common fuel types below together with the advantages and disadvantages of each and things to take into consideration.
Advantages: High energy contentent, i.e. in relation to heat output by weight. Gas in a gas cartridge is compressed to liquid form in a ratio of 250:1 to its original volume. Gas is preferable at extreme altitudes as it still combusts well despite the shortage of oxygen. Added to which, our gas cartridges contain an optimum mixture for highest reliability, broadest application area and lowest weight. Our gas mixture consists of propane, iso-butane and butane. Gas is a simple and easy choice. No pumping or priming is required and combustion is completely odourless and soot-free. In most countries, you can return gas containers when you buy new ones. Empty containers can also be recycled for their metal.
Disadvantages: Gas performs poorly in extreme cold. You are not allowed to take gas cartridges on board aircraft.
Advantages: This type of fuel is purer than ordinary car petrol. It is often in paint shops and leisure and outdoor pursuits stores. Although ordinary petrol is easier to get hold off, it contains a number of hazardous substances and should only be used if you cannot source white gasoline (lead free petrol is the least harmful of the various vehicle fuels). Petrol is the most readily combustible of all liquid fuels and performs excellently in cold conditions.
Disadvantages: Lower energy content than our gas cartridges. Always take all necessary precautions when handling petrol, as all types are extremely flammable. Petrol also requires pumping and pre-heating.
Advantage: It offers the same energy content as petrol but is more readily available in certain locations.
Disadvantages: Pumping and pre-heating required. The fuel is not as clean as gas and white gasoline. Which means the stove will require more maintenance if you use kerosene, as it can become clogged with soot. Gives off a bad odour while combustion.
Advantage: Has an equivalent energy content as kerosene and availability is very good.
Disadvantages: The quality can vary; depending on which part of the world you are in. The stove will require more maintenance compared with using kerosene and this can be quite comprehensive, depending on the diesel quality. Gives off a strong odour during combustion. Diesel should be used as an emergency fuel only.
When travelling around the globe it can sometimes be tricky to find the correct fuel, which is why we have set up the Fuel-i-pedia whit correct names of specific kind of fuel.
Save energy and keep warm
Once you have boiled water, do not tip away the leftovers. Fill the rest into your vacuum bottle or food container in order to isolate it from the cold. You can later use it for the preparation of the next meal or hot drink. And you can use the vessel as a heating inside your sleeping bag when you stay out overnight. Place the bottle at the bottom of your sleeping bag and you will have warm feet for the next couple of hours.
Drinking a lot is essential in low temperatures. And it is not just about something warm to drink, it is about the liquid intake that is mandatory: Breathing in cold air brings along a constant ullage. Additionally, you have a significantly reduced thirst in cold temperatures. Thus, your body needs to be protected from dehydration as this process implies the danger of both frostbite and hypothermia.
In spite of all these risks and things to consider, winter trips are extremely rewarding. I love them. Nature is more intense, there are less people, it is like cleaning your brain. Just give it try!
