Solution

1. Tire Maintenance

Check and Inflate Tires:
- Use a tire pressure gauge to measure PSI.
- Inflate tires to the recommended PSI found in the owner's manual or door jamb.
Inspect Tread Depth:
- Use a tread depth gauge to ensure tread is adequate.
- Replace tires if tread depth is below 2/32 inches.

2. Air Filter Replacement

Remove Air Filter:
- Open the hood and locate the air intake box.
- Unclip or unscrew the air filter housing.
Inspect and Replace:
- Remove the old air filter and check for dirt or damage.
- Replace with a new air filter that meets OEM specifications.

3. Engine Oil Change

Drain Old Oil:
- Use a socket set to remove the oil drain plug and allow oil to drain into a pan.
Replace Oil Filter:
- Use an oil filter wrench to remove the old filter.
- Apply a thin layer of new oil to the gasket of the new filter and install it.
Add New Oil:
- Replace the drain plug and refill the engine with the recommended oil type and capacity.

4. Fuel System Cleaning

Use a Fuel Additive:
- Purchase a quality fuel system cleaner compatible with gasoline engines.
- Follow the manufacturer's instructions for use, typically adding it to a full tank of gas.

5. Driving Habits Adjustment

Promote Efficient Driving:
- Avoid rapid acceleration and hard braking.
- Maintain a steady speed and use cruise control on highways when appropriate.
- Reduce idling time by turning off the engine when parked or waiting.
