a device for facilitating the process of draining oil from a sump having a drain plug . the device includes a flexible oil - resistant sheet - like apparatus having a periphery and an oil drain tube and having a wrench shaft traversing the sheet through an oil - sealing gland . the flexibility of the sheet allows the wrench shaft to be aligned with the sump drain plug . elastic bands attached to the sheet periphery are provided for attachment to structure above the oil sump for raising the sheet periphery above the level of the drain plug whereby the flexibility of the sheet allows it to assume a concave shape so that oil released from the sump is retained and flows out the oil drain tube .
