The invention provides an anti-theft fuel oil control method. The anti-theft fuel oil control method comprises the following steps that firstly, an anti-theft system is started to detect whether the vehicle speed is smaller than a set vehicle speed value or not, the anti-theft system is switched to be in a defense state and begins to detect an initial fuel value of a current fuel tank, detect the fuel value within each sampling period and judge whether the fuel value of a later sampling period is smaller than that of a previous sampling period or not if the vehicle speed is smaller than the set vehicle speed value, the current fuel value is compared with the initial fuel value when a counter performs accumulation and an accumulated value is equal to a first set value, and an alarm signal is given out when the difference of the current fuel value and the initial fuel value is greater than a second set value. By adoption of the technical scheme, the defect that alarming cannot be performed when a key switch is turned off, namely the anti-theft system is started, an engine is in an idle-speed state but fuel is stolen in the prior art is overcome, the anti-theft capacity is improved, and meanwhile the power consumption of a storage battery is reduced. The invention further discloses a fuel oil control system applied to the anti-theft fuel oil control method.
