ABSTRACT:
A small gasoline engine with a relatively inaccessible crankcase oil fill port is equipped with an elongated funnel member having its bottom sealingly secured in that port. A removable cap for the funnel member comprises a suction chamber having a transparent side wall and the interior of which is communicated with a depending tube that has its bottom end at the prescribed minimum oil level. With adequate crankcase oil, depression and release of a downwardly displaceable, upwardly biased top wall of the suction chamber draws oil into it to be visible through its transparent wall. The interior of the transparent wall is cleaned of residual oil by a wiper moving in unison with the displaceable wall.
