The Oil and Oil Filter Retention Device features a container that can be fit about a mounted oil filter. Fitting within the rear of this container is a filter-encasing end cap oil filter wrench, and this wrench can encase the rear circumference of the mounted oil filter. A rod extends from the rear-center of the filter wrench and through the rear-center aperture of the container, and a rubber bushing fits about the tube aperture of projection to prevent any leakage of oil from the container. Attached upon the exterior end of the rod is a gripping cog, for ease of removal once the oil filter is broken loose from its mount. This gripping cog is also hex shaped in order to accommodate a standard wrench. The center of which features an indentation for the insertion of a standard ratchet wrench.
