The invention discloses an oil level detection method for a light oil storage system. The method comprises the steps that the initial oil level height h20 of the medium oil level in oil storage equipment under the standard condition of 20 DEG C is determined in advance; expansion coefficients, corresponding to the multiple temperature intervals, of the medium are determined; according to the initial oil level height h20, the position of the current oil level in oil storage equipment is determined, and the height increment corresponding to the position of the oil storage equipment is determined; a corresponding expansion coefficient is determined according to the medium in the oil storage equipment and the current actual temperature of the medium; and the actual oil level height h is determined according to the determined height increment and the initial oil level height h20. The real-time oil level height signal is analyzed, the real-time temperature is collected to calculate the height increment, the precisi
