in this video we’re going to be discussing what happens when an engine has no oil. As a demonstration, we’ll be viewing an engine with and without oil running. This is the exact same engine on the left and the right, on the left with oil, and on the right without. Both engines will start at the exact same time, but the video on the right was filmed 24 hours after the video on the left, allowing for the engine to completely cool. This is a 212 cc air-cooled single-cylinder Harbor Freight engine.
