Solution

1. Tire Maintenance

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the recommended PSI (found in the owner’s manual or on the driver's door jamb).
Rotate Tires: If uneven wear is noted, rotate the tires according to manufacturer's guidelines.
Alignment Check: Have a professional check wheel alignment to ensure optimal contact with the road.

2. Air Filter Replacement

Locate the Air Filter: Open the hood and remove the air filter housing cover.
Remove Old Filter: Take out the old air filter and inspect it for dirt and debris.
Install New Filter: Place a new, clean air filter in the housing, ensuring a snug fit.

3. Engine Tune-Up

Replace Spark Plugs: Follow the manufacturer’s specifications for spark plug replacement intervals. Remove the spark plugs using a socket wrench and replace them with new ones.
Inspect Ignition System: Check for worn ignition coils and replace if needed.

4. Fuel System Maintenance

Fuel Filter Replacement: Locate the fuel filter (may vary by model), relieve fuel pressure, disconnect old filter, and install a new one.
Use Fuel Additives: Consider using a fuel system cleaner to remove deposits from injectors and improve combustion efficiency.

5. Driving Habits Modification

Smooth Driving: Adopt smoother acceleration and braking techniques to enhance fuel efficiency.
Reduce Idling: Turn off the engine if idling for more than a minute.
