What Does a Major Car Service Include?

A major car service is the bigger of the two routine services in most maintenance schedules. It contains everything in a minor service, so the engine oil and oil filter, the fluid top-ups and the safety checks, and then adds the longer-life replacement items and a much wider inspection. In practice that usually means spark plugs and a fuel filter where your schedule calls for them, a full brake, suspension and steering check, and a diagnostic scan of the car’s electronics. The exact list is not standard, and that matters more than most price comparisons do. It comes from your vehicle manufacturer’s schedule for your exact model.

Major service versus minor service

A minor service keeps the engine clean and confirms the car is safe to drive. A major service does that too, then replaces the longer-life parts and inspects the systems a minor service only glances at.

The split in the first three rows follows the minor and major service lists published by AutoTrader South Africa, read on 22 August 2026. Sanlam Reality makes the same point about depth from the workshop side, quoting Johan Visagie: services “are not only about checking oil, water and air filters” but “also include important safety checks, such as checks on brakes, steering and suspension components”.

Which one your car is due for is set by its own schedule.

What actually gets replaced, and what only gets checked

This is the distinction that decides your invoice, and most service menus blur it. Replacing a part costs parts plus labour. Topping a fluid up is cheaper again, and it is not the same as changing that fluid. Checking a part costs labour only, and if the check finds a problem, the fix is separate work, quoted separately.

Both columns follow AutoTrader’s published minor and major service lists, read 22 August 2026, and their in-depth inspection line covering the timing belt or chain, the transmission and the differential oils. Sanlam Reality lists the same ground from the workshop floor, across spark plugs, brake pads, timing belt, fan belt, CV joints and shocks. Every item stays subject to your own vehicle’s schedule.

Read that right-hand column again before you approve a quote. Everything in it is a check. Worn brake pads, a perished drive belt or a fault code that turns out to be a failing sensor are all normal finds at a major service, and they are not normally part of the base service price unless the quote itemises them. Some workshops do write a known wear item into the quote up front, so ask which of yours is included. That is not sharp practice, it is the difference between inspecting a part and replacing it.

The extra fluid services that sit outside the major service

A major service looks after the engine service items and the inspection. The other fluids in your car have their own service points, set by your model’s schedule, and they are usually quoted as separate jobs. On a higher-mileage car one of them often falls due in the same visit, which is another reason one workshop’s total looks bigger than another’s.

• Gearbox oil service. Manual gearbox oil and automatic transmission fluid are separate jobs from the engine oil change. What goes with the fluid depends on the transmission design and the manufacturer’s procedure for it, so some designs call for a filter, a sump gasket or new seals and others do not, and a dual-clutch box has its own procedure again. Ask what your exact transmission needs rather than assuming a standard kit. AutoTrader lists transmission oil under the in-depth inspection at a major service, replaced only at specific high-mileage points.
• Differential oil. Some vehicles have separate axle differentials holding their own oil, and the layout and the service requirement vary by model, so a rear-wheel-drive car, a bakkie, a 4×4 and an all-wheel-drive car are not all the same. AutoTrader has differential oil inspected at a major service, with replacement only at specific high-mileage points.
• Transfer box oil. A vehicle fitted with a transfer case may hold separate oil in that unit, apart from the gearbox and the diffs. Whether it is checked or changed, and at what point, is set by your vehicle manufacturer’s schedule for that model. Many cars do not have a transfer case at all, so ask whether yours does.
• Brake fluid change. A top-up in the service is not a change. Brake fluid draws moisture out of the air over time, and your schedule sets when the old fluid comes out.
• Coolant change. Same principle. Topping the header tank up is not the same as draining the system and refilling it with the correct specification coolant.
• Power steering and clutch fluid. Both are on the top-up list at a service. Replacing either is separate work.

None of these is automatically inside a major service quote. Give the workshop your mileage, ask which ones your schedule has due now, and ask for each as its own line item. Then you can see what the service costs, what the extras cost, and decide what waits.

There is no standard major service

Search “major car service” and you will find a dozen tidy checklists, all slightly different, none written for your car. Your vehicle manufacturer publishes a service schedule for your exact model, engine and year, and that schedule decides what happens at each service and when. Two cars in the same car park, same badge, different engines, can have genuinely different major services. So a published checklist shows you the shape of the job. It cannot check your quote. For that you need the schedule for your registration.

That also explains why intervals in South African guides vary. AutoTrader states that most manufacturers recommend a service every 15 000 km or 12 months, whichever comes first, with minor and major services alternating. Sanlam Reality suggests a major might land nearer the 45 000 km mark. Both are hedged by their authors and generalise across a whole market. If your schedule disagrees with a magazine, your schedule wins.

Why two honest quotes for the same service look different

Ask three workshops for a major service on the same car and you will get three numbers. Some of that spread is real and some is a difference in what is being quoted.

• Different scope. One quote includes the spark plugs your schedule calls for and another leaves them for the next visit. Same car, different work, different total.
• Different parts. Original manufacturer parts and quality aftermarket parts do not cost the same, and a quote rarely says which it has used unless you ask.
• Different labour rates. AutoTrader notes that service costs run higher in Johannesburg, Cape Town and Durban, where operating costs and labour rates are higher.
• Repairs counted, or not counted. A quote that assumes nothing is worn will always look cheaper than one that has already priced the brake pads the car needs.

The fix is boring and it works. Ask for the quote in writing, item by item, with parts and labour shown separately, and ask which items come from your schedule and which are repairs the workshop expects to find. AutoTrader gives the same advice: always request a full quote before authorising extra work.

What a major service costs in South Africa

Cost varies with the car, the parts and what the inspection finds. Fangio Auto quotes per car, and quotes are free.

If your car is still covered, the real question becomes who pays. Our guide on whether car service plans are worth it works through that.

You choose the workshop, and in-warranty work goes in the service book

Worth knowing before you book. None of this is legal advice.

The Competition Commission’s Guidelines for Competition in the South African Automotive Aftermarket set out how servicing works while a car is still under warranty. Paragraph 5.4.1 says manufacturers must recognise and not obstruct your choice of service provider for service, maintenance and mechanical repair work, whether that provider is an approved dealer or an independent workshop. Paragraph 5.4.4 says drivers without insurance cover may repair their cars wherever they choose at any point in the car’s life.

Two limits sit next to that. Paragraph 5.4.2 says the manufacturer has no obligation to pay for service and maintenance work an independent workshop does during the warranty period, so this is a decision about where the work happens, not about who settles the bill. Paragraph 5.4.3 sends insurance-funded motor-body repairs during the warranty period to a manufacturer-approved motor-body repairer, and says plainly that this applies only to repairs claimed through insurance, not to repairs outside the policy and not to servicing or maintenance.

Then the paperwork. Paragraph 5.4.5 obliges independent workshops to record in-warranty work in the customer’s vehicle service book or equivalent record, so the history stays traceable. Paragraphs 5.4.6 and 5.4.8 require the workshop to tell you clearly about the risk of damage from its work, and say that where damage is caused, certain warranty provisions may be voided while others remain severable and enforceable.

That recording duty is written for in-warranty work. After the warranty ends the service book still matters, because it is the record a future buyer reads. These paragraphs come from the Commission’s 2024 Guidelines, the revised version the Commission uploaded in November 2024 and which took effect on 27 March 2025. Read on 22 August 2026.

What to ask before you approve the job

Six questions, asked before the car goes on the ramp, prevent most service arguments.

• Which items come from my manufacturer’s schedule, and which are repairs you expect to find? This separates the service from the work found during the service.
• At my mileage, is the gearbox, diff, transfer box, brake fluid or coolant service also due? These are separate jobs with separate costs, so ask for them as separate line items.
• Are the parts original or aftermarket, and which are you fitting? Both can be right. Ask so you know what you are comparing.
• What is the labour and what are the parts? A single total cannot be compared with anything.
• Will you call me before doing anything that is not on this quote? Get the answer as a yes, and get it in writing.
• Will this be recorded in my service book? Ask even if you assume the answer. That record is what a future buyer reads.

Common questions

Is a major service the same at every workshop?

No. The work comes from your vehicle manufacturer’s schedule for your exact model, engine and year, so a major service on a 1.0 petrol hatchback and one on a 2.0 turbodiesel are different jobs even when the badge is the same. Ask for the quote to be itemised against your schedule.

Does a major service include the cambelt?

Usually no. The timing belt is normally inspected at a service and replaced on its own schedule. That is a separate job with its own cost, because it means stripping the front of the engine. If your car is near that point, ask while it is in. Our guide on when to change your cambelt explains how that schedule is set.

Is the gearbox oil changed at a major service?

Usually not. Gearbox oil, automatic transmission fluid and differential oil are separate jobs, and where a vehicle has a transfer case, your manufacturer’s schedule decides whether and when that oil is checked or changed. AutoTrader’s major service list has the transmission and differential oils inspected, with replacement only at specific high-mileage points. If your mileage puts one of them close, ask for it as a separate line item while the car is already in.

Are brake pads part of a major service?

The brake check is. New pads are not. Brakes are measured for wear at a major service, and if they are near the end of their life the replacement is quoted as separate work. That is a common reason a service invoice comes in above the quote. AutoTrader names unexpected repairs found during the service as the biggest variable in the final cost, so ask up front what the workshop expects to find.

Do I have to use the dealer for a major service?

No. The Competition Commission’s automotive aftermarket Guidelines say manufacturers must not obstruct your choice of service provider, and that an independent workshop must record in-warranty work in your service book. They also say the manufacturer is not obliged to pay for work an independent workshop does while the car is in warranty, so this is a choice about where the work happens, not about who settles the bill. If a service plan is meant to pay, that is governed by your plan contract, so get written authorisation before you book.

How long does a major service take?

Longer than a minor service, because more parts come off and more systems get measured. It depends on the model and on what the inspection finds, so ask for a realistic time when you book.

Can I skip a major service and just do a minor one?

You can, but you are choosing to leave scheduled replacements and checks undone, and the manufacturer put them at that point for a reason. Skipping also leaves a permanent gap in the service record. If the car is under warranty or on a plan, read the terms first, because a missed scheduled service can affect what the manufacturer or plan administrator will cover.
