An apparatus for collecting and storing fluid samples from vehicles and machinery comprises a storage container having a fluid inlet sealed by a cap, the cap having an aperture releasably sealed by a lid. An adapter connects the cap releasably to a fluid outlet coupling port of a fluid sampling device. The adapter comprises a lumen, having an inlet and an outlet aperture, an external screw thread engageable with an internal screw thread of the coupling port and a connector assembly for connecting the adapter releasably to the cap. A penetrable diaphragm provides an airtight seal over a storage region of the storage container. When the adapter is connected to the coupling port and the cap is connected to the adapter, a fluid outlet tube extending from the coupling port extends through the aperture and protrudes through one or more perforations provided in the penetrable diaphragm into the storage region.

An oil drainage apparatus for a lawn mower including a tapered semi-cylindrical upper funnel having a semicircular top surface and a semicircular bottom surface. A semicircular bottom edge of a semi-cylindrical lip is attached to the top surface of the upper funnel. A semicircular top area of a semi-cylindrical middle funnel is attached to the bottom surface of the upper funnel. A semicircular top end of a tapered semi-cylindrical lower funnel is attached to the bottom area of the middle funnel. A substantially U-shaped channel is continuously disposed from the lip to the lower funnel. A crimp protrusion is medially disposed on the lip. A screen is disposed within the interior cavity between the bottom surface of the upper funnel and the top area of the middle funnel. The lip removably extends around a lower portion of a lawn mower oil drain plug.
