[0077] Examples of the present invention will be further described, but the present invention is not limited to these examples.
[0078] [Example]
[0079] use Figure 4 The degradation and deterioration degree measuring device (capacitance measurement unit and permittivity calculation unit) of lubricating oil shown in the figure is based on the following measurement conditions for the following sample oils (i) to (v) (fresh oil, and deteriorated, deteriorating oil) to measure the capacitance component [capacitance (pF)] at 40, 100, 150, 1000 and 10,000 Hz. The result is a change in capacitive component (capacitance) with respect to frequency, as figure 1 shown.
