Tips And Advices - Convert Used Oil to Diesel Car Fuel

Find a steady, reliable source of used oil. Many restaurants will willingly give you their used oil for free if you ask. This oil is typically available in large quantities, making collection necessary only one to two times a week.

Heat your used oil in a wide, deep vat. The oil should be heated to just below the smoking point, and should never be brought to a boil.

Strain the heated oil through a filter and into a new, clean vat. Make sure any small particles are removed from the oil during the straining process.

Test the pH level of the oil to make sure it's more alkaline than acidic.

Add methanol and lye to the oil. The addition of these substances will cause any glycerin in the oil to drop to the bottom of the vat. If the vat is clear, you can watch while this is happening.

Skim the glycerin off of the oil.

Use the converted oil as diesel car fuel in any engine that's built to take diesel.
