Can You Mix Kerosene And Diesel? [Read This First]

Kerosene is also known as diesel fuel oil, while ordinary diesel is known as diesel fuel oil. Some individuals believe it is similar enough to ordinary diesel gasoline that they could try to utilize it interchangeably. Why do they do it, and what problems may they encounter? Continue reading this site to find these answers.

Can you mix kerosene and diesel? Yes, Kerosene may be combined with diesel fuel to get a few advantages. Kerosene is highly beneficial in the winter for modifying the extreme cold weather handling temps of diesel fuel. A ten percent kerosene addition will reduce a diesel fuel mixture’s cold filters plugging level by five degrees. 

In icy weather settings, Kerosene as a mixer may be more cost efficient than cold flow polymers. This is not the only question to be solved , in this article we will solve a few queries like the difference between kerosene and diesel. Can you mix kerosene and diesel in a torpedo heater ? or  is diesel the same as kerosene ?

Is diesel the same as kerosene?

Following the refining process, Kerosene & diesel are byproducts of crude oil. Crude oil, also known as petroleum, is taken from the earth and then transported to a refinery, where different molecular components are extracted. Among these are diesel and Kerosene, frequently mistaken by certain people. As a consequence, people frequently confuse these fuels. While they are crude oil byproducts, their physical and chemical qualities differ, and interchangeable usage may be inefficient in particular applications.

Diesel and kerosene colors:

The hue of diesel is reddish, whereas Kerosene is colorless but may be tinted blue.

Diesel and kerosene applications:

Kerosene is primarily used in residential heating as well as cooling systems. It was also often used in ancient lights. In some nations, Kerosene is substituted for paraffin. Kerosene, on the other hand, generates greater soot than paraffin.

However, diesel is popular because it emits lower Carbon dioxide. And employed in cars as the most excellent alternative to gasoline. It is also employed in various industrial sorts of machinery for its strength and economy.

Diesel and kerosene extraction:

Both types of diesel, as well as Kerosene, are petroleum fuels that are derived from oil refineries. They are molecular elements of crude oil that are distinguished by simple and complicated hydrocarbon chains. Distillation separates these components according to their boiling points. Others have a lower boiling point than water. 

Kerosene is one of them, and it evaporates fast when put on the ground. Diesel is derived just after Kerosene. Before usage, any of these fuels could be blended with additives to increase their quality.

Can you mix kerosene and diesel in a heater?

Yes, mixing kerosene with diesel for heaters is one of the permitted mixes when switching to diesel fuel. You may need to experiment with the ratio a little, such as filling the gasoline tank 2/3 to 3/4 completely using diesel and then using Kerosene to get the rest of the way.

Another option is to blend Kerosene and Diesel in a proper ratio where diesel kerosene mix ratio be 1:3 or 1:5 ratio. One approach to keep the wicks from being entirely destroyed by diesel fuel is to add Kerosene. This is among the most common worries among the general public. And although wicks are inexpensive, they dislike being ruined rapidly. The Kerosene ensures that the diesel burns appropriately. When diesel is burnt on its own, it produces a large amount of carbon. This is something you should avoid.

Can you run a diesel engine on Kerosene?

Can you run a diesel engine on kerosene ? It is determined by your engine.In actuality, kerosene is a suitable fuel for many modern diesel engines. It is produced by a distillation process, which results in clean fuel. This indicates it has no additives, unlike diesel. As a result, Kerosene burns colder than diesel and contains no lubricating additives like diesel gasoline.

This implies that using Kerosene in the diesel engine will place pressure on the injector pump until you use the proper lubricant. Kerosene should not be used in a diesel engine unless it is listed as an acceptable fuel in the owner’s handbook or you have confirmed with the manufacturer.

What happens when you mix Kerosene and diesel?

Let’s see what happens when kerosene diesel mix. Diesel is a fuel with a solid molecular composition composed of 34 hydrogen plus 16 carbon atoms. On the other hand, Kerosene does not have a fixed structure; instead, it comprises hydrocarbon chains containing 12 to 15 carbon atoms.

Let’s see what happens when you mix both

Cutting down on emissions:

To reduce emissions, Kerosene is mixed with diesel. The reasoning is that kerosene “burns cleanly” than diesel and produces fewer pollutants.


In icy weather settings, kerosene-like a mixer with diesel may be more cost-efficient and can save you some bucks

Burns drier:

The most prevalent problem is that Kerosene burns dry, harming gasoline pumps. In comparison to diesel, Kerosene has extremely low lubricity. Fuel pumps wear out quickly without lubrication and may burn out after running on Kerosene. Some will mention other wear components, such as rings, gaskets, and valves. The simple solution is to mix some automatic transmission lubricant into the Kerosene.

Mixing fuels for torpedo heater:

You can use any combination of Kerosene and diesel in your torpedo heater. A 1:4 ratio is often recommended.

Toxic fumes:

Kerosene burns clean and does not produce too many toxic fumes. Furthermore, diesel doesn’t burn cleanly, resulting in poisonous vapors that may be detrimental to you. Their mixture can help reduce the toxic fumes as when diesel is mixed with Kerosene, the diesel will burn less, resulting in less poisonous fumes.


Because Kerosene burns colder than diesel, this can diminish engine output and impair gas mileage. While the resistance to gelling is an excellent feature of using Kerosene with diesel, the power loss and economy are not worth it.

How much Kerosene do you mix with diesel?

The term “kerosene blended diesel fuel” refers to a combination of kerosene with diesel fuel. Diesel kerosene mix ratio are commonly in the 80/20, 70/30, 60/40, or 50/50 range.

How to mix Kerosene in a diesel?

To mix Kerosene with diesel, you must follow the given ratios, i.e., 80/20, 70/30, 60/40, or 50/50 range. By taking them into consideration, you can easily mix Kerosene with diesel.

Check the fuel content:

To determine the quantity of fuel in the car, look at the fuel gauge on the instrument panel. If the vehicle has a reserve / auxiliary tank, include the amount of gasoline in the total.

Figure out the ratio:

Determine the desired Kerosene to diesel ratios based on the environment in which the vehicle works. At temperatures of 14 degrees Fahrenheit (-10 degrees Celsius), lower volumes of Kerosene, such as 20 components to 80 components of diesel fuel, are applied. For lower temperatures, slowly raise the quantity of Kerosene.

Check the labels:

Before you fill up, read the pump label. Do not make assumptions about the kind of fuel delivered solely on the color of the pump handle.

Add in the fuel:

Add the specified quantity of Kerosene to the vehicle fuel tank using the proper pump.

What burns cleaner, diesel or Kerosene?

There is also an environmental difference between kerosene and diesel, kerosene burns cleaner. Diesel is perfectly acceptable. It will evaporate slowly and leave more residue behind, protecting the metal. Kerosene leaves less residue, making it “cleaner,” but it also makes the metal “bare.”

You should lubricate or protect anything cleaned with Kerosene as soon as possible.

How can you tell if Kerosene is in a diesel?

How can you identify kerosene diesel mix? Monitoring adulteration in vehicle fuels is sometimes intricate due to the resemblance of adulterant characteristics to gasoline. Kerosene in diesel fuel is likely to raise the distillation recovery (at 360 °C) of power over its required value of 95 percent, owing to Kerosene’s lower boiling range when compared to diesel.

In other words, Kerosene contaminated diesel samples would require a lower temperature to accomplish 95 percent distillation recovery than pure diesel samples.


The primary rationale for combining diesel fuel and Kerosene is to increase cold flow operability. Kerosene has a higher cold filter plugging point (CFPP) than diesel fuel, allowing it to flow through a filter at lower temperatures than untreated diesel fuel.

Here in this blog, we have come across a few points on the topic of kerosene diesel mix.
