Owning a car isn't just about driving; it's about maintaining your investment. Many car owners in Thailand fall into the trap of only fixing things after they break. However, following a strict maintenance schedule is the secret to extending your car's life, ensuring safety, and—crucially—maintaining a high resale value.

Whether you are a new car owner or driving a seasoned vehicle, here is your essential guide to car maintenance from 10,000 to 100,000 kilometers.

1. The Basics: Every 10,000 km (or 6 Months)

At every 10,000 km interval (10k, 20k, 30k...), these are the non-negotiables:

• Engine Oil & Filter: The lifeblood of your engine. In Thailand’s hot weather and heavy traffic, oil degrades faster. Changing it ensures your engine runs smooth and cool.
• Tire Rotation: Swapping front and rear tires ensures even wear, extending their lifespan.
• Visual Inspection: Mechanics should check fluid levels (wiper fluid, coolant) and look for any obvious leaks.

2. The Intermediate: Every 20,000 km (or 1 Year)

In addition to the 10k checklist, add these items:

• Air Filter: A dirty filter chokes your engine, reducing power and increasing fuel consumption.
• Cabin Air Filter (A/C Filter): Vital for your health. It traps dust and PM2.5. If your A/C smells musty, change this immediately.
• Wiper Blades: Thailand’s sun hardens the rubber, and heavy rain demands good visibility. Change them if they streak.

3. The Major Check: Every 40,000 km (or 2 Years)

The "Big Service." This is where fluids get flushed.

• Brake Fluid: Moisture builds up in brake fluid over time, making brakes feel "spongy." Flush it for safety.
• Transmission Fluid (Gear Oil): Crucial step. While some manuals say "lifetime," Thai mechanics recommend changing it every 40k km due to heat and stop-and-go traffic.
• Coolant (Radiator Fluid): Prevents overheating. Check the concentration and top up or flush if dirty.
• Power Steering Fluid: (For hydraulic systems) Check for leaks and clarity.

4. The Critical Milestone: 80,000 - 100,000 km

The "Renewal" Phase. Parts are wearing out, and ignoring them can lead to engine failure.

• Timing Belt: If your car uses a belt (not a chain), this is the deadline. A snapped timing belt can destroy your engine instantly.
• Spark Plugs: Worn plugs cause misfires and poor fuel economy. Replace them to restore pep to your engine.
• Battery: Most batteries in Thailand last 1.5 - 2 years. By this mileage, you are likely on your second or third battery.
• Drive Belts: Check the fan belt and air-con belt for cracks or squeaking sounds.
• Tires: By 50k-80k km, your tires are likely bald or hard. Replace them for safety.

Summary

Sticking to this schedule doesn't just keep you safe; it keeps money in your pocket. A well-maintained car consumes less fuel and sells for a much higher price when you decide to upgrade.
