Car Maintenance 101: A Guide for Used Car Owners in Metro Manila

Owning a used car is a great way to enjoy the benefits of having a vehicle without breaking the bank. But to keep it running smoothly, regular maintenance is essential. Metro Manila's heavy traffic, unpredictable weather, and road conditions can take a toll on your car, making upkeep even more important.

Beyond following traffic rules and practicing defensive driving, knowing how to maintain your car is important for your safety and that of others on the road. Proper maintenance helps prevent issues like sudden unintended acceleration (SUA), faulty brakes, overheating engines, and other mechanical failures.

This guide breaks down essential car maintenance tips to help you extend your vehicle's lifespan, boost performance, and ensure your safety on the road.

Why Car Maintenance Is So Important

Proper car maintenance doesn't just keep your car running—it improves safety, efficiency, and value. Here's why car maintenance should always be a priority:

• Ensures Road Safety — A well-maintained car prevents accidents caused by mechanical failures. Routine checks on brakes, tires, oil, and alignment help catch issues early.

1. Check Oil and Fluids Regularly

Let’s start with the basics: oil. Regular oil changes are crucial, especially with the intense heat in Manila, so it’s essential to change your oil every 4,000 to 10,000 kilometers, or every 3 months to a year, depending on your manufacturer’s recommendations. Check your oil level using the dipstick and top it or replace it as needed.

But it’s not just oil—brake fluid, transmission fluid, coolant, and power steering need attention, too. When these fluids get low or old, your car’s performance drops, and in the heavy traffic of Metro Manila, you don’t want to risk a breakdown. Keep those fluid levels topped off to avoid unnecessary headaches.

2. Inspect and Maintain Your Battery

A dead battery is one of the quickest ways to ruin your day—and possibly your week. Metro Manila’s heavy traffic, combined with prolonged sun exposure, can accelerate battery wear, making regular inspections crucial.

To avoid getting stranded, check your battery terminals for corrosion, ensure the battery is securely fastened, and test the charge periodically. A typical car battery lasts about three to five years, but frequent idling, air conditioning use, and short trips can shorten its lifespan. If you notice a slow engine start, dim headlights, or electrical malfunctions, it may be time for a replacement.

Select the Right Battery Type

• SLI (Starter, Lighting, Ignition) batteries: The most common batteries available in the market, and are affordable.
• Lithium-ion batteries: Found in hybrids, lightweight but pricier.
• Lead-acid batteries: Low maintenance but have a moderate lifespan.

3. Maintain Proper Tire Condition

Given Metro Manila’s uneven road conditions and frequent traffic stops, your tires endure a lot. Check the tire pressure at least once a month and maintain the recommended PSI levels. Rotate your tires every 10,000 kilometers to ensure even wear and improve fuel efficiency. Also, inspect the tread depth—balding tires can be dangerous, especially during the rainy season.

Know When to Replace Your Tires

• Visible cracks or sidewall bubbles
• Tread reaches wear indicator
• Older than five years

4. Check and Service Your Brakes

Your car’s braking system is crucial for safety, particularly in Metro Manila’s stop-and-go traffic. Listen for unusual noises like squeaking or grinding when braking, as these may indicate worn-out brake pads. Get your brake pads and fluid checked every six months to prevent potential failures.

Use the Correct Brake Fluid (Depending on the Manufacturer’s Recommendation)

• DOT3: Common for most vehicles.
• DOT4: More heat-resistant but absorbs moisture quickly.
• DOT5: High performance but expensive.

Brake fluid should be replaced every 40,000 km, and brake pads should be changed when they wear down or produce noise. Resurfacing rotors and checking handbrake cables ensure optimal braking efficiency, reducing the risk of accidents in heavy traffic conditions.

5. Keep Your Air Conditioning System Efficient

With Metro Manila’s hot and humid climate, a well-functioning air conditioning system is a must. Clean or replace the cabin air filter regularly to prevent dust buildup and maintain good airflow. Have a professional check the refrigerant levels and inspect for leaks to keep your AC running efficiently.

6. Take Care of Your Engine and Transmission

Used cars may have accumulated wear on their engines and transmissions. To keep them in peak condition, follow the manufacturer’s service schedule. Regularly check for oil leaks, listen for unusual engine noises, and ensure that the transmission fluid is at the proper level to avoid costly repairs.

Use the Right Transmission Fluid

• Gear oil (for manual transmission)
• ATF (Automatic Transmission Fluid)
• CVT fluid (for continuously variable transmissions)

Transmission fluid should be replaced every 40,000 km using the manufacturer-specified type. Manual transmissions require clutch inspections, including checking friction plates and hydraulic components. Proper maintenance prevents slipping and ensures smooth shifting.

7. Clean and Protect Your Car from Rust

Metro Manila’s pollution, road dust, and occasional flooding can take a toll on your car’s exterior. Wash your car regularly to prevent dirt buildup and wax it to protect the paint. If your vehicle has been exposed to floodwaters, have it inspected immediately to prevent rust and electrical issues.

8. Inspect and Maintain Electrical Systems and Lights

Your car’s electrical system powers essential components like headlights, brake lights, and dashboard indicators. Check these regularly to ensure they function correctly, as faulty lights can lead to accidents or fines. If you notice flickering lights or slow power window operation, it may be time to inspect your alternator or wiring.

9. Listen for Unusual Noises and Watch for Warning Lights

Strange noises or dashboard warning lights should never be ignored. If you hear rattling, knocking, or hissing sounds, have your car checked immediately. Warning lights indicate potential issues, from engine troubles to low tire pressure, so address them promptly to prevent bigger problems.

10. Schedule Routine Professional Check-Ups

Even if your car appears to be running fine, it’s best to schedule routine check-ups with a trusted mechanic. A professional inspection can detect hidden issues before they escalate, helping you save money on major repairs.

Stay Ahead of the Game

Owning a used car in Metro Manila can be a smart and budget-friendly choice, but proper maintenance is key to keeping it roadworthy. By following these essential car maintenance tips, you can ensure your vehicle stays reliable, fuel-efficient, and safe for daily commutes and long drives alike. Keep up with regular servicing, stay attentive to warning signs, and enjoy hassle-free driving!
