Why is a regular oil change important for emissions?

A regular oil change is vital for maintaining the overall health and efficiency of the engine, which directly impacts emissions. When engine oil becomes dirty or degrades, it can lead to increased friction and wear on engine components. This not only affects the performance of the engine but can also result in incomplete combustion of fuel. As a consequence, harmful emissions, such as unburned hydrocarbons and carbon monoxide, can increase.

Keeping fresh, clean oil in the engine supports optimal lubrication and encourages proper combustion processes, reducing the amount of pollutants released into the atmosphere. Therefore, regular oil changes are necessary not just for the longevity of the engine, but also for minimizing harmful emissions, making it essential for both vehicle performance and environmental standards.
