Regular maintenance of a vehicle is crucial in ensuring that the vehicle's emissions remain low. When a vehicle is properly maintained, aspects such as the engine, exhaust system, and fuel delivery components function effectively, reducing harmful emissions. This includes ensuring that the engine is running at optimal performance, which minimizes the amount of unburned fuel that escapes into the atmosphere. Regular tasks such as oil changes, replacing air filters, and checking the exhaust system help in maintaining the cleanliness of emissions and ensuring compliance with environmental regulations.

While increasing fuel efficiency, extending the vehicle's lifespan, and improving acceleration are all benefits of regular vehicle maintenance, the primary focus concerning emissions is on maintaining low levels of harmful substances such as carbon monoxide, hydrocarbons, and nitrogen oxides. By keeping the vehicle in good working condition, vehicle owners play a significant role in reducing overall pollution and contributing to a healthier environment.
