Interim, Full, Or Major: Which Car Servicing Does Your Car Actually Need?

5 Signs Your Car Needs A Service

Booking a service should be simple, yet the moment you start looking you are faced with three or four options and very little explanation of the difference. Interim. Full. Major. Oil and filter change. Most drivers pick one at random, or pick the cheapest, and hope it covers whatever the car needs. It does not have to be a guess. Once you know what sits behind each level, choosing becomes straightforward.

Why Car Servicing Comes In Different Levels

Cars wear at different rates. A low-mileage runabout doing school runs has very different needs from a car covering 20,000 miles a year on motorways. Rather than charging everyone for the same lengthy inspection, garages offer tiered options. Each step up adds more checks and covers parts that wear more slowly. Our own car servicing comes in three levels, so there is something suitable whether your car needs a quick top-up or a thorough going-over.

The Oil & Filter Change

This is the lightest option and the easiest to understand. Old oil comes out, a fresh filter goes on, and new oil goes in. Nothing more.

It suits drivers who cover high mileage between their bigger services, or anyone who wants to keep the oil clean in between appointments. Oil does not last forever. It picks up debris, thins out and stops protecting the engine as well as it should. An oil change is cheap insurance, but treat it as maintenance rather than a substitute for a proper inspection.

The Interim Service: A 40 Point Check

The interim option is the middle ground, and for many drivers it is the sensible annual choice. It runs to a 40 point check, covering the basic elements of the vehicle and giving the car a proper look over so that emerging problems get spotted before they turn into something expensive.

This is the real value of an interim service. It is not just about what gets replaced on the day. It is about a technician noticing a leaking shock absorber or a brake pad that is close to its limit, so you can plan the repair instead of being caught out by it. Our advice is to book an interim service between your larger ones, keeping the car under regular review across the year.

The Major Service: A 60 Point Check

The major service is the most thorough option, running to a 60 point check. It covers everything an interim service includes, then goes further into the parts of the car that rarely get examined.

That means the chassis, suspension, transmission, driveshafts, gearbox, clutch and bearings all come under inspection. These are components that tend to fail slowly and quietly, and by the time you notice a symptom the repair bill has usually grown. Checking them regularly is how you catch wear early.

A major service makes sense for older cars, high-mileage cars, or any vehicle that has gone a long stretch without a detailed inspection. It also suits anyone planning to sell, since a full history of thorough car servicing reassures a buyer.

How To Choose The Right Level For Your Car

Start with three questions. How many miles do you cover in a year? How old is the car? When did it last have a detailed inspection rather than a quick one?

High mileage or an older vehicle points towards a major service. Modest mileage on a newer car usually means an interim service will do. If you cover very high mileage, an oil and filter change between appointments keeps the engine protected. Your handbook will also list the manufacturer’s recommended intervals, which is worth checking before you book.

If you are still unsure, ask. A decent garage will look at the mileage and history and tell you honestly what the car needs rather than pushing you to the most expensive option.

What Else Happens While Your Car Is In

Servicing often uncovers work that sits outside the inspection itself, such as tyre repairs, brake work, battery replacement or exhaust repairs. Our team handles mechanical repairs alongside servicing, so faults found during the check can usually be dealt with without booking the car in again. Plenty of drivers also pair a service with their MOT test to save a second trip, and you can see the full range of work we take on across our garage services.

Getting The Most Out Of Every Appointment

A little preparation goes a long way. Clear the car of clutter, make a note of any noises or warning lights, and mention anything that feels different when you drive. Our guide on how to prepare before your next car service covers this in more detail. The more you tell the technician, the more use you get from the inspection.

Frequently Asked Questions

How Often Should I Book A Service?

Most cars are serviced once a year, though mileage matters as much as time. Check your handbook for the manufacturer’s recommended interval and book sooner if you cover high mileage.

Is An Interim Service Enough On Its Own?

For newer cars with modest mileage, it often is. We would usually advise an interim service between your fuller ones, rather than relying on it every single year indefinitely.

What Is The Difference Between The 40 Point & 60 Point Check?

The 60-point major service covers everything in the interim check and adds inspection of the chassis, suspension, transmission, driveshafts, gearbox, clutch and bearings.

Does A Service Replace An MOT?

No. They are separate. A service is about maintenance and condition, while an MOT is a legal test of roadworthiness. Many drivers book both together.

Can You Work On My Make Of Car?

We work on a wide range of makes and models, including cars, vans, motorcycles and scooters.

Will I Be Told Before Extra Work Is Done?

We are a family-run garage built on transparency and upfront pricing with no hidden costs, so you will be kept informed.
