Corrosion– It is a process where oil breaks down and creates corrosive compounds. These compounds make sludge on the engine parts and restrict the engine from its smooth functioning. Due to corrosion, your engine can start consuming more engine oil, resulting in an extra burden on your pocket over time.

Wear and tear– When oil breaks down in corrosive compounds it loses its ability to appropriately lubricate certain parts of the engine. Due to this, wear and tear of those parts become faster which results in early engine breakdown.
