Abstract
Abstract An insert is arranged for mounting in association with an oil fill tube, such as typically utilized in internal combustion engines. The insert includes a cylindrical tube, with an annular collar coaxially and fixedly mounted to an upper terminal end of the tube. The collar receives the fill tube within an annular groove defined by the collar. A plurality of intersecting, triangular webs are fixedly mounted within the tube defining a coaxially oriented projecting and piercing tip to pierce an associated foil seal of conventional oil deposit and containers.
