Periodic Car Maintenance by Mileage: A Global Guide
By Unbroken
When should you service your car by mileage?
Follow whichever comes first — the mileage interval or the time interval — because both matter. For many cars, basic service falls due every 10,000 to 15,000 km (6,000 to 9,000 miles) or once a year, while heavier wear items can wait longer. Your owner's manual sets the exact schedule.
A mileage-based maintenance table helps drivers stop guessing and keeps repair costs from piling up. It is useful anywhere, because stop-and-go traffic, summer heat, cold winters, short urban trips, and long highway drives all affect wear differently. A car that covers 8,000 km (5,000 miles) a year may still need an annual oil-and-filter service, while a taxi or high-use family car can reach the same interval in just a few months. The right schedule is not only about engine health; it also supports safety, resale value, and a smoother pass at your next periodic inspection.
As a rough map: around 10,000–15,000 km (6,000–9,000 miles), expect an oil-and-filter change and a basic safety check. Near 30,000 km (19,000 miles), add cabin and engine air filters, a brake inspection, and fluid top-ups. By 60,000 km (37,000 miles), plan for spark plugs on many petrol engines, brake fluid, coolant checks, belt inspection, and possibly a transmission service. Timing belts, where fitted, often fall due between 60,000 and 150,000 km (37,000–93,000 miles) — a critical, engine-saving job. Always defer to the manufacturer's figures for your specific model.
Driving conditions can pull these intervals earlier. Hot climates, dusty roads, towing, heavy loads, frequent short trips, and extreme cold are all classed by manufacturers as severe service and shorten the recommended intervals. If most of your driving fits that profile, treat the shorter interval as your default rather than the optimistic long one printed for ideal highway use.
