## Abstract

An oil pan leak guard that is attachable to the undersurface of an oil pan. The leak guard has a wire framework, an oil absorbent material supported by the wire framework, and a washer integrated with said wire framework. The washer provides a leak guard opening that receives the oil plug of the oil pan. The washer is clamped against the oil pan when the oil plug is received through the leak guard opening, screwed into the oil plan opening, and tightened.

## Claims
