Abstract: An oil void fraction is measured by a simple way. A method of measuring an oil void fraction comprises a step of obtaining each oil void fraction of a plurality of sample oils, the void fraction thereof already-known, that are introduced into a closed space, compressing each sample oil with a predetermined pressure and measuring a volume change of the sample oil when compressed, and obtaining a calibration line for each sample oil, that is a linear function by connecting values represented by a product of the pressure at OkPa and the volume change plotted against the pressure when it is compressed to the predetermined pressure, a step of obtaining a value of a test oil sample having an unknown void fraction, that is represented by a product of the pressure at OkPa and the volume change plotted against the pressure when it is compressed to the predetermined pressure; and a step of determining the unknown void fraction of the test oil sample by comparing the value of the test sample oil to the calibration line of each sample oil.
