A water level indicator having an upper housing, with a cavity, having a plurality of indicator flag caps disposed within the cavity, and a plurality of pushrods, wherein each indicator flag cap is connect to one of the plurality of pushrods, and each of the pushrods may have a different length. A plurality of floats, each having a locking hole, which receive and secures one of the plurality of pushrods. A first floats of the plurality of floats has a locking tab that secures the second end of a first pushrod, and the float having at least one through hole which allows a second pushrod of the plurality of pushrods to pass through the first float cage and the first float.

An oil level display device is fitted such that a float guide accommodating a float is attached to an oil filler neck and is plugged with a float cap. To check the amount of oil, the float cap is removed and the position of the float is checked. If a sufficient amount of oil is stored, an upward force derived from oil buoyancy is larger than a downward force of the own weight of the float, from among the forces that act on the float. The float thus protrudes beyond a large-diameter portion upon removal of the float cap from the float guide.
