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.
