Abstract
An engine with an engine casing and a dipstick. The dipstick extends into the engine casing and has a free end. The design of the free end may be selected such that the natural frequency of the dipstick does not resonate with the operating frequency of the engine. The dipstick may also be oriented such that the free end does not contact the engine.
