PURPOSE: A refueling unit price providing method is provided to supply calculated information to a driver by calculating actual oil price information by considering the accuracy of a refueling amount. CONSTITUTION: A gas station information collector(106) of a gas station search device(105) extracts a fixed quantity error rate and an actual refueling price based on lubricator state information collected from gas station management clients(101-103). A gas station evaluation unit(107) stores a gas station evaluation result in a refueling management database(109) based on the extracted information. A gas station search engine(108) provides information about the cheapest gas station to a driver.
