How to make diesel fuel from used motor oil?

With an uncertain price of crude oil and high cost of fuel, many new technologies are emerging that provide consumers alternatives to simply pulling up to the nearest gas pump and filling up. That's converting used motor oil to diesel fuel with waste oil distillation machine.

Then how to make diesel fuel from used motor oil? Here are used motor oil to diesel fuel production process:

First, pump dirty motor oil into the waste oil distillation machine.

Second, we need to heat dirty motor oil and keep it at the best temperature for the best diesel quality. Fuel oil will be converted to diesel oil gas when heating.

Then, our cooling system will cool diesel oil gas into diesel.

Next, pump diesel into odor and color removal system to remove which will purify further diesel with special catalyst.

Finally, you can get 80%-85% diesel from our converting motor oil to diesel fuel plant.

The diesel fuel made from used motor oil can be used in any diesel burning vehicle or generator. As an added benefit, these new fuel alternatives are cleaner burning and less harmful to the environment than regular gasoline and diesel.

In fact, except for the 80%-85% diesel, you can also get 15%-25% asphalt. They have a wide usage in our daily life. For the 80-85% diesel oil, you can use it in heavy machinery, generator, and boiler. For the 15%-25% asphalt, could be used for paving, or directly sold to asphalt refineries for further refining.


Now you must be very clear about how to make diesel fuel from the used motor oil working process. Making diesel fuel is becoming more popular, not only for its relative simplicity but also due to the abundance and minimal cost of obtaining used oils. Most small garages keep discarded oil in huge containers that they pay to have removed. This helps keep the overall cost of the ready-to-use fuel.

However, except for how to make diesel fuel from used motor oil, most customers are concerned about the profitable situation through the process. As some customers who have basic understanding of the equipment, they will directly ask us about the profitability of the equipment. Taking five tons of waste oil distillation machine as an example, we have made the following profit analysis for your reference:

ROI Analysis For 5T/D Oil Distillation Machine
Running Cost / Day
                Waste engine oil                5Ton * RMB1800/Ton = RMB9000
                Heating fuel (Diesel)                0.4Ton * RMB4800 = RMB1920
                Catalyst                RMB600
                Electricity                15Kw/h * RMB1*20h = RMB300
                Water                Water is for circulation use, no consumption
                Worker                2 * RMB100 = RMB200
Income / Day
                Light oil (Diesel & Gasoline)                4Ton * RMB4800 = RMB19200
                Oil sludge                0.75Ton * RMB1100 = RMB825
