How Used Motor Oil Burns:
- It can be used as a fuel source in certain waste oil heaters designed to burn oil efficiently.
- When heated, the oil breaks down and combusts, releasing heat energy.
- In some industrial applications, used oil is burned for heating or power generation.
Should You Burn Used Motor Oil?
