Solution

1. Regular Maintenance

Oil Change: Use the manufacturer's recommended oil type and change intervals (typically every 5,000 miles for conventional oil, 10,000 miles for synthetic).
Air Filter Replacement: Replace the air filter every 15,000 to 30,000 miles or as needed. A clean filter ensures optimal airflow to the engine.

2. Tire Maintenance

Check Tire Pressure: Ensure tire pressure is set to the recommended PSI (usually found on the driver’s side door jamb). Inflate tires to the proper pressure if needed.
Rotate Tires: Rotate tires every 5,000 to 7,500 miles to ensure even wear, which can impact fuel efficiency.

3. Driving Habits

Smooth Acceleration and Braking: Practice gentle acceleration and braking to avoid unnecessary fuel consumption.
Reduce Idling: Turn off the engine when parked or waiting for extended periods.
Maintain Speed: Use cruise control on highways to maintain a constant speed, improving fuel economy.

4. Upgrade Components

Install Low Rolling Resistance Tires: Consider replacing current tires with low rolling resistance options designed to improve fuel efficiency.
Engine Tune-Up: Conduct a tune-up to ensure spark plugs, ignition system, and fuel injectors are functioning optimally.
