Lighting a fire is a challenging task, especially when it comes to using diesel fuel. While some people claim that diesel fuel can be easily ignited with a match or lighter, others argue that it is challenging to light diesel fuel on fire with a blow torch or by directly applying a flame. The difficulty in igniting diesel fuel is due to its higher flash point compared to gasoline, requiring higher temperatures for ignition. However, it is important to note that diesel fuel can be ignited under certain conditions, such as when it is heated enough to turn into flammable fumes or when using a Swedish firesteel, a steel bar made from a special alloy including magnesium that produces sparks even when wet. Additionally, mixing diesel with other fuels like gasoline or kerosene can enhance flammability, but it is crucial to exercise caution as these mixtures can be highly dangerous and polluting.

What You'll Learn
Diesel is harder to ignite than gasoline
Diesel fuel is harder to ignite than gasoline due to its higher flash point. Diesel has a flash point of around 62°C, while gasoline has a flash point of around -40°C. This means that diesel requires a higher temperature to evaporate into a vapour and ignite. Gasoline, on the other hand, evaporates at much lower temperatures, making it easier to create vapours that can be ignited with a single spark.
The difference in ignition methods between diesel and gasoline engines also contributes to the difficulty in lighting diesel fuel. Diesel engines use compression to increase the temperature and pressure in the cylinder, which leads to auto-ignition of the diesel vapours. Gasoline engines, on the other hand, use a spark plug to ignite the gasoline-air mixture. This spark plug provides the necessary spark for ignition, which is not required in diesel engines.
Additionally, diesel fuel is less flammable than gasoline. In a car, it takes intense pressure or a sustained flame to ignite diesel. Gasoline, on the other hand, can be easily ignited by tossing a match into the vapours above the liquid surface. This is because the vapours, not the liquid itself, are what burns and ignites. Lighting the liquid fuel directly is more difficult and results in a sooty flame that doesn't effectively spread the fire.
While diesel fuel is harder to ignite than gasoline, it is not impossible to light. Some people have reported success in lighting diesel fuel with a match or lighter, especially when used on campfires or bonfires. However, it is important to note that using diesel or gasoline for fires can be highly polluting and hazardous. It is recommended to use alternative fuels or catalysts, such as dry wood, paper, cloth, or candlewax, for starting fires.

It can be lit with a match or lighter
While diesel is a good fuel source, it is harder to ignite than other fuels. This is because diesel has a higher flash point than gasoline, and it needs to be heated enough to turn into fumes before it can be lit.
However, it is still possible to light diesel fuel with a match or a lighter. If you are using a match, you can soak a piece of paper or cloth in diesel and light that. This method can also be used with a lighter. Alternatively, you can use a blow torch that is powerful enough to heat the liquid and ignite it.
If you are lighting a fire with diesel, it is important to light the fire from the bottom up, rather than the top down. This will help the fire catch. You can also try lighting a piece of dry wood and placing it with the diesel-soaked materials.
It is worth noting that lighting diesel fuel can be dangerous and is not recommended. It is very polluting and produces a lot of CO.

It's best to light it from the bottom up
It is not easy to light diesel fuel, and it is certainly harder to ignite than gasoline. This is because diesel has a much higher flash point than gasoline and is harder to ignite at ambient temperatures.
However, diesel can be lit and there are several methods to do so. One way is to use a blow torch that is powerful enough to heat the liquid. Another method is to tear out pages from a phone book, soak them in diesel, and then ignite them with a lighter. It takes a minute or two for the diesel to begin to burn. You can also use a paper towel. Soak it in diesel and light it.
If you are lighting a fire with diesel, it is best to light it from the bottom up. This is true for both wet and dry fires. If you are lighting a wet fire, split off the bark from a reasonable diameter log, chop up the core into thin sticks, and light them with a match and a bit of dry cotton cloth or paper. Then, build your wet fire on top of the dry one so that the wet material dries out and then burns.

It can be mixed with gasoline to reduce hazard
Mixing diesel and gasoline is not advisable and can be dangerous. However, some people do mix the two fuels to reduce the hazard of lighting gas and achieve a longer, slower burn.
Diesel and gasoline are both derived from crude oil, but they have different properties. Diesel is denser and more stable than gasoline, requiring more compression to ignite. Gasoline, on the other hand, has a lower flash point and burns at a lower temperature. Due to these differences, mixing the two fuels can cause issues in engines and fuel systems.
When gasoline is mixed with diesel, the octane rating of the gasoline is reduced. The octane rating measures the fuel's ability to ignite at the right time. A lower octane rating can cause the gasoline to ignite too early, leading to potential damage to the engine. Additionally, since diesel is heavier than gasoline, it can sink to the bottom of the gas tank, resulting in the injection of both fuels into the engine, which can cause deposits and damage over time.
Despite the risks, some people have reported successfully mixing diesel and gasoline for bonfires or waste burning. It is important to note that burning fuel, in general, is polluting and hazardous, and mixing diesel and gasoline may not always produce the desired results. The ratio of diesel to gasoline can significantly impact the burn, with higher proportions of diesel making it harder to ignite the mixture.
While it is possible to mix diesel and gasoline, it is not recommended due to the potential hazards and negative impacts on engines and fuel systems.

It's a very good, cheap wood preserver
Diesel is not an effective fuel for lighting fires. Kerosene is a better option. However, diesel is considered a good, cheap external wood preserver for sheds, doors, and window frames. It is especially effective when mixed with creosote or another oil-based product.
If you are looking for a cheap and effective way to preserve your wood, diesel is a great option. It is important to note that diesel is not the best fuel for lighting fires. Its high flash point makes it difficult to ignite at ambient temperatures. In fact, if you try to light a match after dipping it in diesel, the fuel will extinguish the flame.
However, diesel can be lit with a match or lighter if you are patient. First, tear out a few pages from an old phone book. Soak these pages in diesel and leave them to sit for a minute or two. The diesel will start to burn after a short while. You can then use this small flame to light your fire.
Alternatively, you can use a "Swedish firesteel" to light your fire. This is a steel bar or rod made from a special alloy that includes magnesium. When you scrape it with a metal tool, such as the back of a knife blade, it produces a shower of sparks—even if it is wet.
While diesel may not be the best fuel for lighting fires, it is a good, cheap option for preserving wood. Just be sure to use it safely and follow proper procedures when lighting your fire.
