What happens if you accidentally put unleaded in a premium car?
The ‘science’ behind it. Premium gas has a higher-octane level than regular gas; or, in other words, a higher resistance to detonation. As various pressures rise inside of the cylinder of the engine, this will also result in a temperature rise, and the gasoline will sometimes detonate, or, “explode” in the cylinder.
