We all know why your engine needs oil, how important it is to change the oil in your vehicle, but what happens when there is no oil in it at all?

An internal combustion engine will run without oil for the little while, but then it will quickly destroy itself, often in spectacular fashion.

That is the subject of the video below from Engineering Explained, where host Jason Fenske first points the thermal camera at the cheap single-cylinder engine running with oil, and then the same engine running without.

Without oil, the engine runs for around 15 minutes without bursting into the cloud of smoke, and taking it apart reveals some serious damage.

Lacking proper lubrication, all the metal components in the engine rub against each other, causing the incredible amount of premature wear. If the oil-less engine had run for much longer, well, it very well could have seized.

So, don’t drain your vehicle of oil just to see what happens. Unless you want to buy the new engine.
