An engine oil sampling device for use with an engine containing a quantity of lubricating oil and having a self-sealing centrally bored access plug connected to an engine wall. In one embodiment a tubular assembly is connected, at one end, with a container with its other end coaxially supporting a tubular needle capable of entering the access plug for filling the container. In another embodiment, the tubular assembly is provided, at one end, with a wall portion defining a screw cap for closing the open end of an upwardly open cylindrical container. In both embodiments a grommet frictionally receives the tubular needle to prevent loss of oil from the container. |
