ABSTRACT:
A method for reforming a lubricating oil which includes holding stably a container (6) containing a lubricating oil (5) on a stand (4) being insulated from the earth with four high-voltage insulators (3), and applying an electrostatic potential of 30 to 50 volts by the use of an electrostatic charge generating device (7), to thereby charge electrons to the lubricating oil (5). The charge of electrons converts an unsaturated hydrocarbon (1a) and an aromatic hydrocarbon (2a) in the lubricating oil (5) to a saturated hydrocarbon (1b) or (2b) and a naphthenic hydrocarbon (2c), which reduces the viscosity of the lubricating oil. Accordingly, the use of the lubricating oil (5) in an internal combustion engine lowers the friction resistance therein, which leads to a decrease in the fuel consumption of the engine. The method allows, therefore, the enhancement of fuel economy, in combination with the suppression of oxidation of the lubricating oil itself.
