When does my car need a service?

Use the manufacturer schedule for your car

There is no reliable universal service interval for every vehicle. Start with the handbook, manufacturer maintenance schedule and service indicator where fitted. Requirements can be based on time, mileage, condition monitoring or a combination.

Time and mileage both matter

A low-mileage car can still need scheduled maintenance because oil, brake fluid and other materials age with time. A high-mileage vehicle may reach a mileage interval long before the calendar date. Some vehicles use variable servicing based on operating conditions.

Driving conditions can change the picture

Frequent short journeys, towing, heavy loads, dusty conditions, repeated cold starts or intensive commercial use can justify closer attention to the severe-use guidance in the manufacturer’s information. EVs and hybrids have different maintenance needs from conventional petrol or diesel cars.

If the history is missing

Do not guess that maintenance was done because the vehicle runs well. Gather invoices, digital service records and previous owner information. A garage familiar with the model can help establish a sensible baseline without blindly replacing every service item.

Do not use the MOT date as the service interval

It is convenient to book them together, but an MOT pass does not mean scheduled maintenance is up to date. Keep the two schedules conceptually separate.

What to do next

Use this guide to prepare and ask better questions, not as a remote diagnosis. If a safety-critical defect is suspected, avoid unnecessary driving and arrange a competent physical inspection.
