Car Maintenance Schedule by Mileage: The Complete Checklist

Every car comes with a maintenance schedule, but it’s usually buried in the owner’s manual and written in a way that’s easy to ignore. This is the plain-English version: what to check and replace as the odometer climbs, in both kilometers and miles, for a typical modern petrol car.

Two rules before the table. First, your owner’s manual always wins — these are common intervals, not gospel for your exact engine. Second, service on whichever comes first, distance or time. Oil ages in the sump even if you barely drive.

The maintenance schedule at a glance

Interval (km)	Interval (miles)	What to do
8,000–16,000	5,000–10,000	Engine oil & oil filter (see oil change guide), tire rotation, visual brake & fluid check
16,000–32,000	10,000–20,000	Engine air filter, cabin air filter, inspect brakes & tires closely
40,000–48,000	25,000–30,000	Brake fluid, inspect belts & hoses, battery test, wheel alignment
48,000–64,000	30,000–40,000	Transmission fluid (many autos), spark plugs (some), coolant check
96,000–160,000	60,000–100,000	Timing belt (if fitted), coolant flush, spark plugs, suspension, water pump

Use it as a map, then let the app do the remembering. In Kotselog you set each item’s interval once and log your mileage as you drive; it nudges you before anything falls due. Open the app and add your car to start a schedule in under a minute.

Every few thousand kilometers: the basics

The short-interval items are the ones that quietly protect the expensive parts.

• Engine oil and filter. The single most important service. Depending on oil type this is every 8,000–16,000 km (5,000–10,000 mi) or every 6–12 months. Full detail in how often should you really change your oil?
• Tire rotation. Every 8,000–13,000 km (5,000–8,000 mi) evens out wear and extends tire life.
• Quick checks. Tire pressure, tread, lights, wiper blades, and fluid levels — a two-minute walkaround once a month catches most problems early.

Watching your fuel economy is a free diagnostic here: a steady drop in km/L or MPG often means a dirty air filter, low tires, or a service that’s overdue.

Mid-life: filters, fluids, and brakes

Between roughly 16,000 and 64,000 km, the “consumables” that don’t announce themselves need attention:

• Air and cabin filters — restricted airflow costs you power and fuel; a clogged cabin filter weakens your air conditioning.
• Brake fluid — it absorbs moisture over time and should typically be replaced about every 2 years regardless of distance. See when to change transmission, brake, and coolant fluids.
• Transmission fluid — many automatics want fresh fluid around 60,000–100,000 km; some “lifetime” fills still benefit from a change.

The big one: 96,000–160,000 km

This is the service people dread because it’s genuinely important. If your engine uses a timing belt (not a chain), replacing it on schedule is non-negotiable — a snapped belt can destroy the engine. It’s also when coolant, spark plugs, and suspension components typically come due. Plan and budget for it; it’s far cheaper than the failure it prevents.

Keep the records

A complete service history isn’t just for your peace of mind — it raises resale value and helps a mechanic diagnose faster. Logging each service (date, mileage, cost, what was done) also feeds straight into your true cost of ownership. Kotselog keeps that history per vehicle, so the whole story of your car lives in one place.
