The handbook and service indicator are the best starting points. Driving pattern matters too: frequent short journeys can be demanding even when annual mileage is low.
The short answer
- Follow the manufacturer time or mileage interval—whichever comes first—unless the vehicle specifies a different system.
- Short trips, towing, heavy loads and high mileage can justify additional checks or more frequent maintenance.
- An MOT and a service do different jobs; a valid MOT does not confirm that scheduled maintenance is complete.
Follow time and mileage limits
Manufacturers usually specify an interval by time and mileage, whichever comes first. Some cars calculate condition-based reminders, but that does not replace regular tyre, fluid and safety checks.
Consider how the car is used
Repeated short trips, towing, heavy loads, dusty conditions and high annual mileage can change maintenance needs. Ask a garage to relate its recommendation to the manufacturer schedule.
Interim or full service?
An interim service can help high-mileage vehicles between scheduled visits. A broader service may include more replacement items, but package names vary.
Quick checklist
- Keep itemised invoices
- Check warranty requirements
- Record the correct oil and parts
- Do not confuse an MOT with servicing
Find the schedule for your exact vehicle
Check the handbook, in-car service information, manufacturer portal or a reliable garage using the registration or VIN. The interval can vary by engine, model year, oil specification and fixed or flexible schedule even within the same model range.
A service indicator may show remaining time or mileage, but also check date-based items such as brake fluid or cambelt recommendations that may not share the same countdown. Record what was completed, not just that a “full service” occurred.
Low mileage does not mean no maintenance
Cars that cover few miles can still reach time limits. Short journeys may leave the engine repeatedly cold, while tyres, batteries, fluids, wipers and brakes age even when the odometer moves slowly.
Do not extend an interval based only on appearance or a recent MOT. Ask a garage to relate its recommendation to the manufacturer schedule and the way the car is used.
Questions drivers ask
Should a car be serviced every year?
Many schedules use a time or mileage limit, whichever comes first, but intervals vary. Follow the exact manufacturer schedule for the vehicle.
Does an MOT include an oil change?
No. An MOT is an inspection to defined standards; routine oil and filter replacement belongs to servicing.
