Abstract: The present invention, a cap for liquids with a visible float gauge, is comprised of a hollow, cylindrical cap made of transparent material, a color coded display of levels and/or a text display, and a fixed inner cylinder. The inner cylinder is attached to the cap top at its top end. The inner piece is concentrically placed in the cylindrical cap inside of the float gauge, and a float gauge is internally retained by the cap. The cap is then screwed on to a liquid reservoir as is found on a typical internal combustion engine, whereupon the float gauge floats on the liquid and is seen through the transparent part of the cap. The float gauge is the indicator, giving a liquid level reading.
