Which of these options can burn fuel cleaner?

Keeping your vehicle well-tuned and tires properly inflated is vital for burning fuel more cleanly and efficiently. A well-maintained engine ensures that fuel is combusted effectively within the engine, leading to optimal performance and lower emissions. Regular maintenance tasks, such as replacing air filters, spark plugs, and oil, contribute to improved fuel economy and cleaner burning by ensuring that the engine runs smoothly without unnecessary strain.

Additionally, properly inflated tires reduce the rolling resistance that your vehicle experiences on the road, which also aids in fuel efficiency. Under-inflated tires can lead to increased drag and require the engine to work harder, thus consuming more fuel and creating more emissions. Therefore, maintaining your vehicle and its tire pressure is one of the most effective ways to promote cleaner fuel burning and enhance overall efficiency.
