The invention relates to the technical field of oil product analysis, in particular to a gas station oil product analysis method and a gas station oil product analysis system. The gas station oil product analysis method comprises the steps S1, obtaining mileage information, in-vehicle electric appliance information and geographic information of a vehicle, and detecting the oil quantity change condition of the vehicle in real time; S2, if the proportion of the new oil is greater than a preset proportion, obtaining the nearest gas station information, and starting an oil product analysis period;S21, calculating the oil consumption per hundred kilometers; S22, recording current driving habit data, and analyzing a driving style; S23, judging the influence of the driving style on the fuel consumption, and analyzing the current fuel quality under the same driving style. The gas station oil product analysis system comprises an acquisition module, a processing module, a positioning module, abackground cloud and a communication module. According to the method, driving style analysis and fuel consumption after refueling are combined. The quantitative scoring is carried out on the fuel. Theobjective fuel reference is provided for a vehicle owner, and adverse effects of bad fuel on economic expenditure of the vehicle owner and the vehicle are avoided.
