Oil Change Video Posted on May 6, 2023September 3, 2024 by Eddie Here’s a video of me changing the oil on another Delorean. I made the video with some of my fellow car club members. Notes: -The socket needed is a 8mm External Square Socket. I purchased the Snapon version, PMM408A.-The anti-drain back valve keeps oil from draining out of the oiling system and filter when the engine is shut off. The engine will receive oil immediately upon start up.-I need to lose about 10 – 15 lbs.
