Usage
Oil change intervals: months vs kilometres
Short city trips oxidise oil even when the odometer barely moves. Long highway months burn kilometres before the calendar catches up. That’s why good schedules use whichever comes first — typically around 6 months or 10,000 km for many petrol cars (always check your manual).
