Abstract

An oil dipstick for use in measuring the oil level in an oil receptacle such as the crankcase of an automotive vehicle, including an elongated rod that is received in a wiping member in frictional contact therewith and is movable outwardly of the crankcase relative to the wiping member, wherein oil is removed therefrom by contact with the wiping member. A locking member is secured to the rod and is engageable with the wiping member for selectively locking the wiping member to the rod, so that the wiping member and rod are removable from the crankcase as a unit for a reading of the oil level on the rod.
