摘要

PROBLEM TO BE SOLVED: To provide a lubricating oil additive, such as an antioxidant, which does not undergo deterioration with time in an antioxidant action, is nontoxic and safe, and is inexpensively produced and to provide a lubricating oil.;SOLUTION: The lubricating oil is formed by colloidally distributing powdery tourmaline in a base oil. The powdery tourmaline acts as an antioxidant. It is more effective when used as an engine oil which is exposed to stimuli such as violent heat, impacts, vibrations, or light. The longer the base oil is used, the further it is reduced to prevent its oxidation. The lubricating oil antioxidant additive is friendly to the environment because it comprises tourmaline which is added as a minus-ion-generating source to health water. Therefore, when it is added to a lubricating oil and is discharged in an exhaust gas, it is harmless to humans.;COPYRIGHT: (C)2004,JPO
