Symptoms: The oil level drops between services (more than half a litre per 1,000 km and up to a litre or more), usually from 150,000–200,000 km; bluish smoke.

Check for the garage: Check the history for oil top-ups or replaced pistons; measure consumption between two changes and check the spark plugs.
