Kerosene and diesel are both fuel types derived from petroleum, but they differ in several ways. Kerosene, also known as paraffin or lamp oil, is a clear, colourless liquid with a high flash point, making it less likely to ignite spontaneously. It is commonly used in aviation and small engines, as well as for heating and cooking. Diesel, on the other hand, is a reddish colour and is almost exclusively used for vehicles. While kerosene is typically cheaper and performs better in freezing temperatures, it is less fuel-efficient and can damage diesel engines due to its lack of lubrication.

What You'll Learn
Kerosene and diesel are both derived from petroleum
Kerosene, also known as paraffin or lamp oil, is a clear, colourless liquid derived from petroleum. It is used for lamps, small engines, heating, and cooking in certain parts of the world. Kerosene has a high flash point, making it less susceptible to spontaneous ignition than other fuels, and it is also relatively stable and easy to store. It is widely used in aviation and specific diesel engines. In regions with freezing temperatures, kerosene is occasionally used as a substitute for diesel fuel.
Diesel, on the other hand, is a reddish derivative of petroleum that is almost exclusively used for vehicles. It has a higher boiling point than kerosene and is typically more expensive. Diesel is considered a more refined fuel compared to kerosene, which contains impurities and contaminants impacting performance and stability.
While kerosene can be used in some diesel engines, it is not recommended as a regular substitute due to various risks. Kerosene burns at a lower temperature, reducing fuel efficiency and engine power. Additionally, the lack of lubrication in kerosene can damage the injector pump of a diesel engine unless lubricant is added. Using kerosene in vehicles not designed for it may void the engine warranty and lead to legal liabilities in certain countries.
Both kerosene and diesel have distinct characteristics and applications, and while they share a petroleum base, they are not interchangeable without careful consideration of the potential benefits and drawbacks.

Kerosene is used for heating and cooking in some parts of the world
Kerosene, also known as paraffin or lamp oil, is a clear, colourless liquid derived from petroleum. It is used for lamps, small engines, and for heating and cooking in some parts of the world. Kerosene has a high flash point, which means it is less likely to ignite spontaneously compared to other fuels. It is also relatively stable and easy to store.
Kerosene is widely used for heating in Japan, Chile, the United Kingdom, Ireland, and other parts of the world. In Chile and Japan, kerosene can be bought at any filling station or delivered to homes. In the UK and Ireland, it is often used as a heating fuel in areas not connected to a gas pipeline network. In the United States and Canada, kerosene is used for heating in regions with freezing temperatures, as it doesn't gel as quickly as diesel.
Kerosene is also used for cooking in some parts of the world, particularly in low and middle-income countries, including Nigeria, India, Nepal, China, South Africa, and Tanzania. It is also used for cooking in some urban areas of developing countries, where biomass needs to be purchased and electricity and LPG are expensive or unreliable. Kerosene is sometimes advocated as a cleaner-burning fuel compared to solid fuels like biomass, wood, agricultural residues, and animal dung. However, the World Health Organization (WHO) has declared kerosene a polluting fuel and discouraged its use in households. This is because kerosene smoke contains particulate matter that can lead to adverse health effects, such as respiratory issues, hypertension, and an increased risk of mortality.

Kerosene has a higher flash point, making it less prone to ignite
Kerosene, also known as paraffin or lamp oil, is a clear, colourless liquid derived from petroleum. It is used as a fuel for lamps, jet engines, heaters, and small engines, as well as for cooking and heating in certain parts of the world. Notably, kerosene has a high flash point of 38°C (100°F). This makes it less prone to spontaneous ignition compared to other fuels, including diesel.
The flash point of a fuel refers to the lowest temperature at which it gives off enough vapour to ignite when exposed to a source of ignition. Kerosene's high flash point contributes to its stability and ease of storage. In contrast, fuels with lower flash points, such as gasoline, are more prone to ignition and require careful handling.
The high flash point of kerosene has implications for its use in engines. Kerosene is commonly used in aviation and some types of diesel engines. It is particularly advantageous in cold climates, as it does not gel as quickly as diesel fuel in freezing temperatures. This property makes it a preferred choice for preventing fuel filter blockages in diesel vehicles during winter.
However, using kerosene in diesel engines comes with certain risks. Kerosene burns at a lower temperature than diesel, which reduces fuel efficiency and engine power. Additionally, the lack of lubrication in kerosene can damage the injector pump of a diesel engine unless lubricants are added.
While kerosene has a higher flash point than diesel, it is important to note that it is still a combustible and flammable substance. It should always be handled and stored with care to prevent accidents.

Kerosene is more expensive than diesel
Kerosene, also known as paraffin or lamp oil, is a clear, colourless liquid derived from petroleum. It is used for lamps, small engines, and for heating and cooking in certain regions. Kerosene has a high flash point, making it less prone to spontaneous ignition than other fuels. It is commonly used in aviation and some diesel engines.
Diesel, on the other hand, is reddish in colour and is almost exclusively used for vehicles. While kerosene is sometimes used as a substitute for diesel fuel, particularly in cold climates, it is generally more expensive for several reasons.
Firstly, kerosene is highly refined, which contributes to its higher price. Secondly, kerosene is in less demand than diesel, which can drive up its price. Thirdly, kerosene is subject to seasonal variations in price, with higher prices during the winter when it is used to winterize diesel fuel. Finally, kerosene is sold in smaller quantities, such as by the gallon, which tends to be more expensive than purchasing in bulk.
The price difference between kerosene and diesel is notable, with kerosene costing up to $20 per gallon in some cases. This price discrepancy can be attributed to the factors mentioned above, as well as variations in geographical location and the specific type of kerosene being purchased.
In summary, while kerosene may offer certain advantages, such as smoother performance in freezing temperatures, its higher price compared to diesel is a significant consideration when choosing between the two fuels.

Kerosene can be used in diesel engines, but it is harsher on the engine
Kerosene and diesel are both derived from petroleum, but they have distinct chemical compositions and uses. Kerosene, also known as paraffin or lamp oil, is a clear, colourless liquid with a high flash point, making it less prone to spontaneous ignition than other fuels. It is commonly used in aviation, small engines, heating, and cooking in certain regions.
Diesel, on the other hand, is reddish in colour and is primarily used as a vehicle fuel. It has a higher boiling point than kerosene and is considered a refined fuel. While diesel typically refers to the fuel type "#2", there is also a lesser-known variant called "#1 diesel" or "diesel #1", which is sometimes referred to as kerosene.
Despite their differences, kerosene can be used in diesel engines. In fact, some diesel engines list kerosene as an accepted alternative fuel. Kerosene is particularly useful in cold climates as it has a lower freezing point than diesel and does not gel as quickly, making it ideal for preventing gelling in freezing temperatures. However, it is important to note that using kerosene in a diesel engine can be harsher on the engine due to its lack of lubrication. This can lead to potential damage to the injector pump, reduced engine power, and decreased fuel efficiency.
Additionally, there are legal considerations when using kerosene in vehicles. In Canada and the United States, using untaxed and unvetted fuel on public roads is prohibited, and using kerosene in a vehicle not meant for road use could result in a fine. It is crucial to consult the vehicle's manual and warranty information before considering kerosene as a fuel alternative. While kerosene may offer cost savings, the potential risks to the engine and legal liabilities should be carefully weighed.
