Car Service Schedules Explained: Fixed, Long-Life and EV Servicing

Most cars follow one of two service patterns: a fixed schedule, usually every 12 months or a set mileage, or a variable "long-life" schedule where the car tells you when it is due. The right interval for your car is in the handbook or the service booklet, and following it keeps the car reliable and protects its value.

What is a fixed service schedule?

A fixed schedule sets a service at a time or mileage interval, whichever comes first. Many petrol and diesel cars follow a yearly pattern, often alternating between an interim service and a full service. If you do lots of short trips, tow, or drive in heavy traffic, the maker may recommend its "severe use" schedule with shorter intervals.

What is a variable or long-life service?

Some cars, often German brands, use a variable schedule. The car monitors how it is driven and the condition of the oil, then shows a message when a service is due. The gap can be longer than a year for cars that do steady motorway miles, and shorter for cars used on short trips.

Long-life schedules need the correct long-life oil. If a car mostly does short local journeys, it can make sense to switch to a fixed yearly schedule. Ask your service centre which suits your driving.

What about electric cars and hybrids?

Electric cars have no engine oil, spark plugs or timing belt, so they usually need less routine work. They still need brakes, tyres, suspension, cabin filters, coolant and brake fluid checking on schedule. Hybrids follow a schedule much like a petrol car, with extra checks on the hybrid system.

What should a service include?

It varies by schedule and service type, but expect most of these:

• engine oil and filter change (petrol, diesel and hybrid);

• brakes, tyres, steering and suspension checked;

• fluid levels checked and topped up, with brake fluid and coolant changed when due;

• air, cabin and fuel filters replaced at the intervals set by the maker;

• lights, wipers and battery checked;

• the service reminder reset and the service recorded.

Our guide to what happens in a car service explains each step.

How is service history recorded now?

Many newer cars no longer come with a stamped paper book. Instead, the service is logged on the maker's digital system or on an invoice. Not every garage can update every maker's system, so always keep your invoices. They prove the work was done and help when you sell the car. Our guide to service history explains what buyers look for.

Common questions

Can I use an independent garage without affecting my warranty?

Usually yes, provided the work follows the maker's schedule and uses parts and oil to the right specification. See our guide to independent servicing and your warranty.

Is a service the same as an MOT?

No. An MOT is a legal safety check. A service is maintenance. Our guide to MOT and service differences explains both.

What happens if I miss a service?

One late service rarely causes immediate harm, but skipped services can lead to worn parts, can affect a warranty, and leave gaps in the history that put buyers off.
