First, it is necessary to change the driving style of the motor vehicle. Clean and inspect the vehicle's fuel system. Replace the vehicle's spark plugs and clean the engine carbon deposits. Replace the vehicle's air filter.

I've been driving this 2007 Focus for a while, and the sudden spike in fuel consumption really puzzled me. After careful consideration, I think it's probably due to driving habits, like frequent hard acceleration or braking which burns more fuel. I've been trying to drive more steadily lately, maintaining a constant speed on city roads and keeping within reasonable speed limits on highways. I also checked the tire pressure and topped it up to the recommended values in the manual, as low pressure increases rolling resistance. I replaced the air filter myself—it only took ten minutes—since a dirty one affects air intake efficiency. Regular maintenance shouldn't be skipped either, like oil and filter changes, or cleaning the throttle body. These are low-cost but can significantly reduce fuel consumption. Paying attention to these small things has helped me cut fuel consumption by 15%, saving money and making driving safer.
