At What Mileage Do You Change the Oil, Filters and Timing Belt?
The intervals below are guidelines. The exact values are always in your car's manual — that's what should take priority.

Maintenance interval table
| Component | Guideline interval |
|---|---|
| Engine oil + oil filter | 10,000 – 15,000 km or 1 year |
| Air filter | ~30,000 km |
| Pollen (cabin) filter | 15,000 – 30,000 km |
| Fuel filter (diesel) | 40,000 – 60,000 km |
| Timing belt | 60,000 – 120,000 km or 5 years |
| Spark plugs (gasoline) | 30,000 – 100,000 km (depending on type) |
| Brake fluid | every ~2 years |
| Coolant | every ~4–5 years |
Things to keep in mind, by component
Oil
The most important interval. Mostly urban driving, over short distances, "tires out" the oil faster — in that case, lean toward the lower end of the interval.
Timing belt / chain
On engines with a timing belt, a broken belt can destroy the engine — don't exceed the interval. Engines with a timing chain don't, in theory, have a fixed interval, but should still be checked periodically.
Filters
The oil filter is changed with every oil change. The other filters have their own intervals — a clogged air filter increases fuel consumption.
💡 Tip: write down the mileage at every intervention. In AutoMeu you log a service record and get an alert as the next service approaches — no need to keep every interval in your head.

At what mileage should you change the timing belt?
As a guideline, 60,000–120,000 km or every 5 years (for belt-driven engines). Don't exceed the interval — a broken belt can destroy the engine.
How often are the filters changed?
Oil filter with every oil change, air filter ~30,000 km, pollen filter 15–30,000 km, fuel filter (diesel) ~40–60,000 km.
