Incorrect Oil Reading 

Hot oil is a mixture of hot oil and hot air. oil expands. This happens because cold oil reacts with hot engines, causing thermal expansion. It causes oil molecules to expand. 

This could lead to low oil levels for a long time. It is possible that your oil tank takes less oil than it used to. As the oil molecules absorb heat from the engine, it will slowly return to its normal level. 

Burned Skin: There is a risk
