There is currently a method for recovering oil known as pyrolysis that involves heating the fuel to a high temperature without oxygen. The oil is converted during pyrolysis into a mixture of gases, liquids, and solids. Although not very readily, it is possible to turn the gases and liquids into gasoline or diesel fuel.
Waste oil is converted into diesel fuel by a chemical process called transesterification. It’s a fancy word for a really straightforward idea. In this procedure, an ester and an alcohol are combined. For the purpose of making biodiesel, cooking oil is mixed with methyl alcohol, or methanol, to form the “ester.”
As a result of the high cost of fuel and the unpredictability of crude oil prices, a number of innovative technologies are emerging that offer consumers alternatives to simply pulling up to the local gas station and filling up. These new fuel options also burn cleaner and are less damaging to the environment than conventional gasoline and diesel, which is a bonus.

The process of converting old motor oil to diesel fuel, which can be used in any diesel-powered vehicle or generator, is gaining popularity because to its relative simplicity as well as the accessibility and low cost of used oils.
Most small garages store their used oil in bulky containers that they hire removalists to take away. This lowers the overall cost of the fuel that is ready to use.
The most effective way to save money and the environment is to recycle spent motor oil into fuel. Quality energy can be produced from used motor oil if it is treated, stored, and handled carefully.
4 Steps How to Make Diesel from Waste Oil
Here are some of the steps that make up the process:
Waste motor oil (WMO) can be collected and placed in an aluminum container that is black to draw heat into the oil without causing it to boil. Do this for a few days in the warm sun.
Oil should never boil; instead, it should only get to the point where it starts to smoke. If the motor oil is boiling, filtering will be challenging and you’ll end up with too much tar and sludge.
Pour the warm oil through a fuel injection filter using an electric inline fuel pump that you can buy from a car dealership.
By keeping the suction hose away from the container’s bottom, you can stop the pump from gathering sludge.
Pre-filters are usually integrated into pumps. Remove any particles that may have gotten through the filtering process and pour the heated oil into a different, clean container.
Back-flushing the filter with gas to clean it. Through the cleaning of the oil, this will advance the filtering process.
Put the filter in reverse and insert the suction hose into a gas-filled pan to do this. After completing this procedure, a clear stream of liquid will flow.
To reduce the oil to micron-sized particles, go through six or seven filters.
A condenser can also be used, which will cause some of the oil to evaporate.

However, employ this procedure sparingly as too much condensation can lead to the evaporation of the diesel and its subsequent loss.
You’ve now succeeded in turning used motor oil into diesel.
