White Gas Vs Denatured Alcohol: What's The Difference?

White gas and denatured alcohol are both types of fuel commonly used for camping stoves and lanterns. While they share some similarities, they also have distinct differences in terms of composition, heat output, efficiency, and suitability for different situations. This comparison between white gas and denatured alcohol will help you decide which fuel type is more suitable for your specific needs, whether it's for camping, hiking, or other outdoor activities.

White gas is more fuel-efficient than denatured alcohol

White gas and denatured alcohol are not the same thing. White gas, or naphtha, is a petroleum product, whereas denatured alcohol is made from ethyl alcohol, the same type of alcohol humans drink, with additives to make it poisonous and unfit for human consumption.

For shorter trips, denatured alcohol is the preferred option as it is lighter. Alcohol stoves are lightweight and easy to operate, and for shorter trips, the fuel weight of the alcohol stove is less than the fuel and stove weight of a gasoline rig. However, for longer trips, the greater fuel weight of the alcohol stove means it can be heavier overall.

The type of stove also makes a difference. Alcohol stoves are better for just boiling water and rehydrating freeze-dried foods, whereas white gas stoves allow you to adjust the flame and are better for cooking real food. Alcohol stoves are also not allowed in no-burn zones due to the lack of a separate fuel tank.

In terms of cost, white gas is generally cheaper than ethanol, and denatured alcohol is more expensive than isopropyl alcohol, the most popular and widely available alcohol type.

Denatured alcohol boils water faster

White gas, or naphtha, is primarily used for cleaning purposes. Denatured alcohol, on the other hand, is a fuel source that can be used for cooking. It consists of 95% ethyl alcohol, which is the drinking kind, and 5% benzine. Denatured alcohol is often used in alcohol stoves for cooking, and its effectiveness in boiling water has been compared to that of HEET (methyl alcohol).

Several factors can influence how quickly denatured alcohol boils water. The type of alcohol stove, the amount of fuel used, and the initial temperature of the water can all play a role. In one test, a user filled their Trangia alcohol stove one-third full of denatured alcohol and started with a pot of cold water. The fuel burned out before the water reached a boil. However, it's worth noting that the stove may not have been filled to maximum capacity, which could have impacted the results.

Another factor to consider is the atmospheric pressure, as the boiling point of alcohol varies with changes in pressure. At sea level, the boiling point of ethanol (ethyl alcohol) is 173.1 °F (78.37 °C), while that of water is 212 °F (100 °C). The boiling point of alcohol decreases as atmospheric pressure decreases, so it will be slightly lower than the published values unless you are at sea level.

While denatured alcohol can be used to boil water, it may not be the most efficient method, especially when compared to other fuel sources like HEET. In certain scenarios, users have reported running out of denatured alcohol before the water reached a boil. However, it's important to note that the stove's design, fuel quantity, and other factors could have influenced these outcomes.

Additionally, the presence of additives in denatured alcohol, such as benzine, could potentially impact its boiling performance. These additives are introduced to make the alcohol undrinkable and unpalatable. Overall, while denatured alcohol can be used for boiling water, its effectiveness may vary depending on various factors, and it may not be the fastest option available.

White gas is better for longer trips

White gas and denatured alcohol are not the same thing, and each has its own advantages and disadvantages. For instance, denatured alcohol is made from ethyl alcohol (the type of alcohol humans drink) but has additives to make it poisonous for human consumption. It also has additives to give it a bitter and unpleasant smell and taste so that people are discouraged from drinking it. White gas, on the other hand, has petroleum naphtha as its active ingredient and is also known as Coleman fuel.

When it comes to longer trips, white gas is the better option. This is because it is much more fuel-efficient than denatured alcohol for Coleman dual fuel camping stoves and lanterns. While denatured alcohol can be used in these stoves, it takes longer to heat water and uses more fuel. White gas also burns cleanly and doesn't leave many carbon deposits, making it safer to use indoors. Additionally, white gas has a higher heat output than denatured alcohol, with almost double the amount of BTUs per pound. This means that white gas will be more effective at heating water and cooking food, which is important when on a longer trip.

Another advantage of white gas for longer trips is its longevity. White gas has a long shelf life and can last for 5 to 7 years, although some people have successfully used decades-old white gas. This is useful when planning for extended periods in the wilderness.

Furthermore, white gas stoves offer more control over the flame compared to alcohol stoves. This adjustability is beneficial when cooking real food that requires different temperatures and cooking times. With an alcohol stove, the stove burns at full speed until the fuel is gone, making it less suitable for cooking meals that require more intricate preparation.

While alcohol stoves are lightweight and easy to operate, especially for shorter trips, the weight savings are offset by the need to carry more fuel for longer excursions. The extra fuel weight can make alcohol stoves potentially heavier overall for longer trips. Therefore, when it comes to longer adventures, white gas is the preferred choice due to its fuel efficiency, heat output, longevity, and controllability.

Denatured alcohol is cheaper than isopropyl alcohol

White gas and denatured alcohol are not the same thing, but they are both used for cleaning. White gas is also known as naphtha, and can be used for cleaning, but will not remove stiffener. Denatured alcohol, on the other hand, will break down the stiffener. Denatured alcohol is ethanol that has been treated with additives to make it unfit for human consumption.

Isopropyl alcohol can be produced from the chemical reaction between propylene and sulphuric acid, followed by hydrolysis. Denatured alcohol, on the other hand, is ethanol that has been treated with denaturants to make it poisonous and repellent to humans. These denaturants can include methanol, benzene, pyridine, castor oil, gasoline, acetone, and even isopropyl alcohol itself.

The most common additive to denatured alcohol is methanol, which is highly toxic when consumed orally. Other additives may include benzene, pyridine, castor oil, gasoline, acetone, and dye to make it easily distinguishable from drinkable alcohol. Denatured alcohol typically contains around 90% pure ethanol and 5% toxic denaturants.

While both types of alcohol are unsafe for human consumption, they can be applied to the skin in the form of hand sanitizers and rubbing alcohol. They are also both highly flammable and should be kept away from open fires or equipment that could spark.

White gas is good for up to seven years

White gas and denatured alcohol are not the same thing and have distinct uses and properties. White gas, or naphtha, is primarily used for cleaning and as a fuel for camping stoves and lanterns. It is derived from petroleum and contains additives to protect equipment from damage. Denatured alcohol, on the other hand, is ethyl alcohol with additives to make it poisonous and unpalatable for human consumption.

Now, onto the topic of white gas's longevity:

White gas is known for its long shelf life and can be stored for up to seven years without degradation. This characteristic makes it a reliable fuel source for camping and outdoor enthusiasts, ensuring that they have a functional fuel source even after years of storage. This extended shelf life is attributed to its stable chemical composition, which remains effective and safe to use over time.

The long shelf life of white gas is a significant advantage for those who enjoy camping, hiking, or simply like to be prepared for emergencies. By storing white gas, individuals can rest assured that their fuel will remain usable for their lanterns, stoves, or other equipment for several years. This longevity eliminates the worry of fuel degradation and the need for frequent replacement, making it a convenient and dependable choice.

It is worth noting that proper storage conditions are essential to maximize the shelf life of white gas. It should be kept in a cool, dry place, away from direct sunlight and extreme temperatures. Additionally, ensuring that the container is sealed tightly will prevent evaporation and moisture contamination, both of which can affect the quality and performance of the fuel.

While white gas has a long shelf life, it is not indefinite. After seven years, the fuel may start to degrade, and its performance may become less reliable. However, some people have reported successfully using white gas that is several decades old, indicating that it can sometimes exceed its expected lifespan. Nonetheless, it is generally recommended to use fuel within the specified timeframe to ensure optimal performance and safety.
