Abstract: An automobile windshield wiper fluid refill device having a collection tray that mounts under a hood of a vehicle, collects rain water and directs it to a washer fluid container to automatically fill the container. The tray has a bottom surface and wall that projects upward from the bottom surface and extends around the sides and front of the tray and terminates near the back end of the tray to define an opening and a pair of drainage ports partially defined by apertures in the wall and a pair of conduits depending from the wall proximal the apertures. The open side of the tray and wall ends engage a wall or drainage plastic piece under the hood of a vehicle when mounted. A flange extends from the bottom surface through the opening for fitting under a plastic drainage piece that all vehicles have under the hood for draining rain water and other water.
