Kerosene, also known as #1 diesel fuel oil, is a lighter diesel oil than #2 diesel fuel oil. It has been suggested that kerosene can be used as a cleaning agent for fuel injectors. However, opinions vary on whether kerosene is effective for this purpose. While some sources claim that kerosene is not an injector cleaner but a fuel, others suggest that it can be used to clean sludge from oil passageways, and that most fuel injector cleaners contain kerosene. Additionally, kerosene can be mixed with diesel fuel to improve cold weather performance and lower emissions.

Kerosene is not an injector cleaner but a fuel
Kerosene is a fuel, not an injector cleaner. Injector cleaners are products designed to clean injectors, such as Powerservice or Stanadyne, and most name-brand fuels already contain an additive package to help keep injectors clean. While kerosene is a component of many fuel injector cleaners, it is not a good idea to use it by itself. This is because kerosene contains a lot of sulfur, and there are usually many other cleaning or detergent ingredients in injector cleaners beyond just kerosene.
Kerosene is a low-viscosity, clear liquid formed from hydrocarbons obtained from the fractional distillation of petroleum. It is a popular choice for heating, lighting, and cooking fuel, and has been used for over a century in homes and businesses. Kerosene is also known as a fuel for stoves and lanterns, and even home furnaces, but it can be hard to come by. It is one of the more cost-effective fuels available because it is fairly inexpensive to produce. Kerosene has a higher flash point than gasoline, meaning it offers higher octane ratings to achieve greater power and efficiency. This is the main reason it is used as a fuel for airplanes.
Kerosene is also safer than some other fuel options, as it does not produce the high levels of carbon monoxide that burning wood or coal does. It also has a low risk of freezing, as it only freezes or "gels" at around -40° F (-40° C). This means it can be stored in outdoor tanks during extremely cold temperatures without turning into a gel that cannot be used.
The World Health Organization (WHO) considers kerosene to be a polluting fuel and has recommended that governments stop promoting its household use. Kerosene smoke contains high levels of harmful particulate matter, and household use of kerosene is associated with higher risks of cancer, respiratory infections, asthma, tuberculosis, cataracts, and adverse pregnancy outcomes.

Kerosene is used in fuel injector cleaners but not as the only ingredient
Kerosene is a fuel that can be mixed with diesel to clean fuel injectors. Kerosene is a lighter diesel oil than #2 diesel, which is the regular diesel used in trucks. Kerosene is designated as #1 diesel and has slightly less energy content. It is also a "dry burn" fuel, which means it has very little lubricity compared to #2 diesel. This lack of lubricity can cause fuel pumps to experience a lot of wear and even burn out.
Kerosene is often used as a solvent to remove sludge from engines. It can be effective in cleaning out the large and narrow oil passageways in a car, allowing the engine to run more efficiently. However, it is important to note that kerosene by itself is not a good idea as a fuel injector cleaner. It contains a lot of sulfur, and there are usually many other cleaning or detergent ingredients in fuel injector cleaners besides kerosene. Kerosene is typically used as a carrier for these other chemicals. Most fuel injector cleaners are 50% to 90% kerosene, with the remaining ingredients being other solvents or detergents.
While kerosene can be used to clean fuel injectors, it is not the only ingredient necessary for an effective cleaner. It is important to add the right lubricant to the fuel when using kerosene to prevent strain on the injector pump. Additionally, kerosene may not be necessary at all, as most name-brand fuels already have an additive package to keep injectors clean. Therefore, while kerosene is used in fuel injector cleaners, it is not the only ingredient, and other solvents, detergents, and lubricants are necessary for an effective cleaner.

Kerosene can be mixed with diesel fuel to improve performance in cold weather
Kerosene, also known as #1 diesel fuel oil, is a lighter diesel oil than #2 diesel fuel oil. It contains slightly less energy, with about 135,000 BTU per gallon compared to 139,000 BTU for a gallon of #2 diesel. Kerosene also has a better cold filter plugging point (CFPP) than diesel fuel, meaning it can pass through a fuel filter at a lower temperature than untreated diesel. This is particularly useful in cold weather, where kerosene can be mixed with diesel fuel to improve performance.
Mixing in ten percent kerosene will lower the cold filter plugging point of a diesel fuel blend by about five degrees Celsius. Therefore, in extremely cold weather, it may be more cost-effective to use kerosene as a mixer than a cold flow polymer. This is because kerosene "burns cleaner" than #2 diesel, leading to lower emissions. Additionally, kerosene contains less lubricity than diesel fuels, which can lead to more wear and tear on engines.
However, it is important to note that kerosene is not an injector cleaner. If your injectors need cleaning, it is recommended to use products specifically designed for that purpose, such as Powerservice or Stanadyne. These products help keep injectors clean, and most name-brand fuels already have an additive package for this purpose. Adding a pint of kerosene to your fuel will likely not make a significant difference in the lubricity, mileage, or cleanliness of your injectors.
Furthermore, while kerosene can be useful in cold weather, it is generally more cost-effective to treat your fuel with a winter fuel additive. These additives are designed to improve vehicle performance and extend engine longevity in cold conditions. They cost less, provide more protection, and improve operability without sacrificing power and performance. Therefore, while kerosene can be mixed with diesel fuel to improve performance in cold weather, it may not be the most economical or effective option.

Kerosene burns cooler than diesel and has no lubricant additives
Kerosene is not a fuel injector cleaner, but a fuel. It is not recommended by professionals in the diesel industry to mix kerosene with diesel fuel. Kerosene is a harsher fuel for your diesel engine, and the lack of lubrication within the fuel can damage your diesel's injector pump. This is because kerosene burns at a lower temperature than diesel, which can prevent gelling in freezing temperatures. However, this also means it is far less fuel-efficient and reduces engine power.
Kerosene has very little lubricity compared to #2 diesel. Without the lubricity, fuel pumps experience a lot of wear and may burn out when running on kerosene. Some people suggest that kerosene burns at a higher temperature than diesel, which may cause damage to engine components such as rings, gaskets, and valves. This is because kerosene has less total energy than diesel, so burning a gallon of kerosene will produce less total heat than burning a gallon of regular on-road diesel.
However, kerosene can be useful in extremely cold weather, as it can be mixed with diesel fuel to lower the cold filter plugging point of the blend. In really cold weather, it may be more cost-effective to use kerosene as a mixer than a cold flow polymer. Mixing kerosene with diesel is also said to lower emissions, as kerosene "burns cleaner" than diesel.
It is important to note that there are risks involved with using kerosene in a diesel engine, and it is not a direct replacement for diesel fuel. While kerosene is typically cheaper than diesel, the potential damage it may cause could result in large repair bills that outweigh any cost savings.

Kerosene is a solvent that can help remove/dissolve sludge
Kerosene is a solvent that can help dissolve sludge in your engine. However, it is not a good idea to use kerosene by itself to clean fuel injectors as it is a fuel and contains a lot of sulfur. Instead, you should use products specifically designed to clean injectors, such as Powerservice or Stanadyne. These additives are often already present in name-brand fuels.
If you are considering cleaning your engine, it is important to note that engines today do not experience the same level of sludge and build-up as they did in the past due to the use of high-quality oils. Therefore, a harsh approach to engine cleaning is not recommended and could be dangerous. If you still wish to proceed with cleaning your engine, it is recommended to use a proven engine flush or MMO (commonly used on BITOG), which is considered a low-risk method.
Some people have suggested using kerosene as a solvent to flush their engines. One method involves mixing engine oil and kerosene, running the engine for a couple of minutes, and then draining the mixture. Another method is to drain the engine oil, refill it with kerosene, let it sit overnight, and then drain the kerosene and replace it with fresh engine oil. However, it is important to note that solvent cleaning requires many oil changes and risks metal-on-metal wear. Therefore, it is recommended to leave things alone or clean them completely, rather than using a strong solvent like kerosene.
