Abstract
A device for measuring engine lubricating oil temperature circulating through the oil lubricating system of an internal combustion engine of a motorcycle. Another advantageous embodiment consists of a stem-type thermometer attached to the wall of the oil reservoir with the temperature sensing stem projecting through an appropriate aperture in the oil reservoir wall. In situations wherein the oil reservoir is connected to the internal combustion engine of the motorcycle by an oil carrying conduit, yet another advantageous embodiment can be employed which consists of a branch conduit projecting from the oil carrying conduit with the temperature sensing stem of the thermometer extending axially into the branch conduit. A further advantageous embodiment consists of a stem-type thermometer having markings along the temperature sensing stem corresponding to various oil levels. The thermometer is mounted to the oil filler cap of the oil reservoir such that when the oil filler cap is in place closing the oil filler port of the oil reservoir, the temperature sensing stem projects into the interior of the oil reservoir.
