Solution

1. Optimize Tire Pressure

Sub-steps:
1. Use a reliable tire pressure gauge to measure tire pressure when tires are cold.
2. Inflate tires to the recommended pressure indicated on the driver’s side door jamb.
3. Inspect tires for uneven wear, which may require alignment or rotation.

2. Regular Maintenance

Sub-steps:
1. Change engine oil using high-quality synthetic oil as recommended by the manufacturer.
2. Replace the air filter if it’s dirty; refer to the owner’s manual for replacement intervals.
3. Ensure spark plugs are in good condition; replace if they are worn or fouled.

3. Improve Driving Habits

Sub-steps:
1. Avoid aggressive acceleration and hard braking; aim for smooth acceleration.
2. Use cruise control on highways to maintain a constant speed.
3. Reduce idling time; turn off the engine if stopped for more than a minute.

4. Reduce Weight and Drag

Sub-steps:
1. Remove unnecessary items from the trunk and interior to reduce weight.
2. If equipped with roof racks or carriers not in use, remove them to decrease aerodynamic drag.
3. Ensure windows are closed during highway driving to minimize drag.

5. Fuel Quality

Sub-steps:
1. Use high-quality fuel from reputable sources to ensure optimal engine performance.
2. Consider using fuel additives that clean the fuel system if necessary.
