How Often Should I Service My Car? Interim, Full, and Major Service Explained

The standard servicing schedule

Most manufacturers recommend servicing every 12 months or 12,000 miles, whichever comes first. If you drive higher mileage each year — say 15,000 or 20,000 miles — you might need a service every six months.

Check your vehicle handbook for your exact manufacturer schedule. The schedule may differ between petrol and diesel, and between model years. When you call us on 0121 544 3736, we can look up the correct interval for your exact car.

What is an interim service?

An interim service (also called an oil service) covers roughly 25 checks and typically takes 1–2 hours. The focus is on engine health: oil and filter replaced, fluid levels topped up, and visual checks of key components like brakes, tyres, and lights.

Interim services are ideal if you drive high miles but want to spread the cost, or if your manufacturer allows them between full services.

What is a full service?

A full service (or major service on some schedules) covers roughly 40 checks and typically takes 2–3 hours. It includes everything in an interim service, plus air filter replacement and deeper inspections of brakes, steering, suspension, and other safety components.

A full service is the standard recommendation for most cars and should be done annually.

What is a major service?

A major service happens less often — typically every 24 months or 24,000 miles on manufacturer schedules. It covers all full-service items plus spark plug changes, fuel filter replacement, and thorough checks of cooling, transmission, and exhaust systems.

Major services keep high-mileage cars running reliably and can catch wear before it becomes expensive.
