1. An apparatus for adding additives to lubricating oil comprising:
- detecting means equipped in a circuit of flow of a lubricating oil, for impressing a high voltage between two points in said lubricating oil and measuring a current therebetween, to determine a TBN of said lubricating oil;
supplying means for selectively supplying additives to said lubricating oil; and
controlling means for controlling a supply of said additives by said supplying means when said TBN detected by said detecting means is outside a predetermined range.
