Can regular engine oil burn?

[DeJayce]

Engine oil itself does not burn. Without any attached materials, it won't ignite even when exposed to an open flame. However, if flammable items are contaminated with engine oil, they can easily catch fire. For safety reasons, it's best to avoid exposing engine oil to open flames. The engine oil inside a vehicle won't burn because combustion in the engine cylinder won't ignite the oil. In current internal combustion engines, diesel engines rely on piston compression for ignition, while gasoline engines use spark plugs. However, both require fuel combustion to generate power. After fuel ignition, piston rings separate the high-temperature, high-pressure combustion gases in the cylinder from the engine oil passages, preventing oil from entering the combustion chamber.
