Engine servicing is far more comprehensive than just an oil change. Since the engine is the heart of your car, neglecting other crucial components can lead to reduced performance, mileage, and a shorter engine life.

Here are five vital things to ensure are checked or addressed during your car's engine service:

1. Engine Oil Level and Quality

Don't just assume the oil has been changed. Both the level and the quality are critical:

• Check the Level: Low oil level reduces lubrication, causing increased friction and quicker overheating. Ensure the technician confirms the level is correct.

• Check the Quality: Old engine oil accumulates carbon deposits, reducing the smoothness of engine operation and significantly degrading performance. Always confirm that fresh, correct-grade oil has been used.

2. Replace the Oil Filter

The oil filter is responsible for catching impurities and preventing them from circulating into the engine.

• Why it's essential: A clogged or old filter stops working effectively, allowing contaminants to damage internal engine components.

• Best Practice: It is highly recommended to replace the oil filter during every service to keep the engine in optimal health.

3. Inspect/Replace the Air Filter

The engine requires a clean, adequate supply of air for combustion.

• Impact of a Dirty Filter: A dirty air filter restricts airflow to the engine, which directly harms your vehicle's fuel economy and pickup (acceleration).

• Action: Have the air filter thoroughly inspected, and replace it if it appears dirty or clogged.

4. Throttle Body Cleaning

The throttle body regulates the air entering the engine. Over time, carbon deposits build up here.

• Benefits of Cleaning: Removing these carbon deposits improves engine performance, restores fuel economy, and contributes to smoother, more responsive driving.

• Action: Make sure throttle body cleaning is included in the service checklist.

5. Check Other Fluids and Belts

Although the article focuses on core engine components, a complete service should always include:

• Coolant Level and Quality: To prevent overheating.

• Brake Fluid Level: For safety.

• Drive Belts/Timing Belt: Check for cracks, fraying, or excessive wear, as a failed belt can cause catastrophic engine damage.
