Question

why do we need to add oil to our car engine ? explain big​

Answer 1

Answer:

Automobile engines have many moving parts. As these parts move and rub against each other, the force of friction creates heat. Oil lubricates the engine and absorbs heat, allowing the internal parts to work together effectively without overheating. Over time, engine oil breaks down and wears out.

If the oil isn't changed, your vehicle's engine will start to have a lot of problems. ... This can cause the engine to run less efficiently, and as time goes on, it can cause the engine components to warp and wear out. The lack of lubrication between these parts will also contribute to these problems.
