7 Steps on How to Burn Waste Motor Oil in a Diesel Engine

The creation of “black diesel” is a necessary processing and conversion step when used in combination with conventional diesel fuel grades. Some people explore with different ways to filter out the silt and pollutants from used motor oil and have developed their own variations on the procedure.

A word of warning: When combining waste motor oil, there is still a chance of harming or permanently breaking down your diesel engine’s fuel system, including your fuel filter and injectors, even after the filtration operations have taken place.

7 Steps on How to Burn Waste Motor Oil in a Diesel Engine

Step 1

Put on your safety gear first. Throughout a large portion of the procedure, you will be heating the diesel oil to extremely high temperatures, which might result in severe burns if the motor oil were to mistakenly run into your flesh.

Step 2

Pour the used engine oil into a container or flask designated for the “black diesel” manufacturing procedure using a funnel.

Using a stovetop and a cooking thermometer affixed to the pot, heat the used motor oil until it reaches a minimum temperature of 300 degrees.

This will thin the oil so you can filter the contaminants out of it. Use a magnet to pick up any bigger metallic fragments that may have become loosened and gotten into the motor oil as it is heating.

Step 3

Set up a second pot and funnel arrangement to collect the oil as it flows through a filter.

Pouring the waste motor oil through a 20-micron filter at least twice while it is still hot will start the filtration process to remove debris and contaminants.

Continue using the same procedure but with filters that are 15 and 10 microns smaller, warming the motor oil as necessary.

Step 4

Using a centrifuge, which can serve as a more effective filter, add the used motor oil. The motor oil will perform at its best when heated, so make sure the centrifuge you’re using can endure high temperatures.

When the sediment you are filtering out does not appear on the other side of the filter, keep using the centrifuge and repeating the process with all of the motor oil.

Step 5

The waste motor oil should be poured into a flask for distillation. The distillation process involves heating the motor oil until it starts to condense and evaporate into the raised flask.

Take the primary distillation flask’s residual motor oil sludge to an auto parts store for disposal.

The motor oil that is still present in the second elevated flask is prepared for mixing with regular diesel fuel.

Step 6

 Pour the “black diesel” into a fuel container and add it to a fully full fuel tank in modest amounts at first. Increase the “black diesel” fuel that you are putting into your fuel tank and engine gradually. Keep an eye out for eventual symptoms of power loss.

If, however, your engine starts to misfire on a regular basis, you might want to stop using your “black diesel” or cut back on its proportion in your diesel fuel mixture.

Step 7

To clean the fuel injectors in your diesel engine, add fuel additives to the fuel tank. When using black diesel, check the fuel filter frequently for blockage and replace as necessary.

Now that you understand how the process of turning spent motor oil into diesel fuel works, you should be able to apply it.

In summary, the first step is to pump used motor oil into the oil distillation facility.

For the greatest diesel quality, we must secondly heat used motor oil and maintain it at the ideal temperature. When heating occurs, fuel oil is transformed into diesel oil gas.

Following that, our cooling system will convert the diesel oil gas to diesel.

Once the color and odor have been removed, the diesel is then pumped into a specific catalyst that further purifies it.

Then, from our facility that converts motor oil to diesel fuel, you can obtain 80%–85% diesel.
