Solution

1. Tire Maintenance

Check Tire Pressure: Use a tire pressure gauge to measure tire pressure; inflate to recommended PSI if low.
Tire Rotation: Rotate tires according to manufacturer schedule to ensure even wear.
Alignment Check: If tires are unevenly worn, have the alignment checked and adjusted.

2. Air Filter Replacement

Locate Air Filter: Open the engine bay and find the air intake housing.
Remove Old Filter: Unclip the housing and remove the old air filter.
Install New Filter: Place a new, clean air filter into the housing and reassemble.

3. Fuel System Cleaning

Use Fuel Additives: Add a high-quality fuel system cleaner to the fuel tank to help dissolve deposits.
Replace Fuel Filter: If applicable, replace the fuel filter according to manufacturer specifications.

4. Engine Oil Change

Drain Old Oil: Place a drain pan under the oil pan, remove the drain plug, and allow oil to drain completely.
Replace Oil Filter: Use an oil filter wrench to remove the old filter and install a new one.
Add New Oil: Reinstall the drain plug and fill the engine with manufacturer-recommended oil type and quantity.

5. Improve Driving Habits

Adopt Smooth Driving Techniques: Accelerate gently, maintain steady speeds, and avoid excessive idling.
Limit Use of Air Conditioning: Use the AC sparingly, as it can increase fuel consumption.
