The invention is a mobile fueling system for vehicles that includes a fleet of mobile fuel stations, such as trucks. Each mobile fuel station has at least one fuel reservoir adapted for storing either liquid fuel, gaseous fuel and electric fuel. The system also includes a data processing hub and a network providing wireless data communication between vehicles, the fleet of mobile fuel stations, and the data processing hub. The data processing hub receives vehicle data from vehicles and fleet data from each mobile fuel station over the network. The vehicle data is transmitted from a customer's smart device running a customer app. The data processing hub is configured to dispatch via the network the mobile fuel stations in the fleet to vehicles in need of fuel based on at least three of the following factors: vehicle fuel level, a vehicle fuel request, vehicle location, a vehicle owner stored fueling location preference, a vehicle owner service request, reservoir fuel contents, reservoir fuel level and mobile fuel station location.
