The method involves assigning color or color combination to a determined fuel grade. Devices e.g. filling pump and/or pump nozzle, are marked or characterized by an automobile manufacturer or vehicle owner by applying materials e.g. foil, plastic, rubber parts and painting, where the devices are used for storing, delivering and filling of the determined fuel grade. An independent claim is also included for a device for minimizing a risk of wrong fuelling of a motor vehicle.
