How Often Should You Service Your Car?

There is no single "service interval"

One of the most common questions new car owners ask is "how often should I service my car?" The honest answer is: it depends on the item. Different parts wear at different rates, and your driving conditions change the picture too.

This guide gives you clear, practical intervals for the most common maintenance items. Always confirm against your owner's manual, which has the manufacturer's specific recommendations for your vehicle.

The golden rule: time or mileage, whichever comes first

Almost every service interval is expressed as "every X km or Y months, whichever comes first." This matters because many drivers drive less than the mileage interval but the parts still age. Oil degrades over time even if the car sits. Brake fluid absorbs moisture even if you do not drive.

If your manual says "every 10,000 km or 12 months" and you drive 5,000 km a year, you still service every 12 months.

Engine oil and filter

The most important service of all:

• Conventional oil: every 5,000 km or 6 months.
• Synthetic oil: every 7,500–10,000 km or 12 months.
• Severe conditions (short trips, heavy traffic, dusty roads): shorten by 30–50%.

Signs you are overdue: dark gritty oil on the dipstick, louder engine noise, or an oil change reminder light. See our Engine Oil Guide.

Air filter

• Inspect every 10,000 km.
• Replace every 20,000–40,000 km, or sooner if you drive in dusty conditions.

A clogged air filter reduces airflow and can affect fuel economy, especially in older vehicles.

Cabin air filter

• Replace every 15,000–25,000 km, or once a year.

This keeps the air inside your cabin clean and your AC working efficiently. A clogged cabin filter reduces airflow and can cause misty windows.

Tyres

• Pressure check: monthly. See our Tyre Pressure Guide.
• Rotation: every 10,000 km to promote even wear.
• Replacement: when tread is low (below 3 mm for safe wet grip) or tyres are damaged.

Brakes

• Pad inspection: every 20,000–40,000 km, or at every service.
• Brake fluid replacement: every 2–3 years (it absorbs moisture regardless of mileage).
• Discs: inspected when pads are replaced; replaced when worn to the minimum thickness.

See our Basic Car Maintenance Checklist for the full brake schedule.

Spark plugs

• Standard plugs: every 30,000–50,000 km.
• Iridium/platinum plugs: every 60,000–100,000 km.

Worn plugs cause misfires, rough idling, and poor fuel economy.

Coolant

• Inspect at every service.
• Replace every 2–5 years or 40,000–100,000 km, depending on the type. Check your manual.

Transmission fluid

• Automatic: inspect every 40,000–60,000 km; replace every 60,000–100,000 km (varies widely — check your manual).
• Manual: replace every 60,000–100,000 km.

Some "lifetime" fluids still benefit from replacement in older vehicles.

Battery

• Test every year after 3 years of age.
• Typical life: 3–5 years depending on climate. Hot climates shorten battery life.

Wiper blades

• Replace every 6–12 months, or when they streak or smear.

Severe driving — shorten everything

If you drive in any of these conditions, shorten your intervals by roughly 30–50%:

• Frequent short trips (under 5 km).
• Heavy stop-and-go traffic.
• Dusty or unpaved roads.
• Towing or heavy loads.
• Extreme heat or cold.

A simple annual plan

| Interval | Tasks | |---|---| | Monthly | Oil level, tyre pressure, lights, washer fluid | | Every 6 months / 5,000–10,000 km | Oil & filter change, air filter check, tyre rotation | | Annually | Full inspection, cabin filter, wiper blades, battery test | | Every 2–3 years | Brake fluid, coolant (check manual), spark plugs (check manual) |

FAQ

What happens if I miss a service? One missed service is not catastrophic, but do not make it a habit. Service as soon as you can — delayed oil changes are the most damaging.

Is the dealer the only place that can service my car? No. Any qualified mechanic can service your car. Keep the records and use the correct parts to protect any warranty.

Should I follow the manual or the dashboard reminder? The manual gives the safe maximum interval. Dashboard reminders are useful but often assume ideal conditions — if you drive in heavy traffic or take short trips, follow the manual's severe-service schedule.
