A major car service is more than a routine oil change. It is a more comprehensive scheduled maintenance visit designed to cover a wider range of inspection, replacement and maintenance items than a basic or general service. The exact work depends on your vehicle, kilometres, age, engine and manufacturer service schedule.
If you are wondering whether your car actually needs a major service, the safest starting point is your owner's manual or service logbook. A service interval is usually based on time, kilometres, or whichever comes first. Do not assume that every vehicle follows the same 30,000 km, 60,000 km or 100,000 km checklist.
This guide breaks down what a major car service can include, how major servicing differs from a basic or general service, what commonly happens at different kilometre milestones, what can cost extra and when you should book one.
What Is a Major Car Service?
A major car service is a comprehensive scheduled service carried out when your vehicle reaches a manufacturer-specified maintenance interval. Compared with a basic service, it can involve more inspection points and replacement of scheduled maintenance items such as filters, spark plugs, fluids, belts or other components where the manufacturer's schedule calls for them.
The word major does not mean there is one universal checklist for every car. A 60,000 km service on one model can be very different from a 60,000 km service on another. Engine type, transmission, driving conditions and the manufacturer's maintenance schedule all matter.
For example, manufacturer schedules can use different time and kilometre intervals depending on the vehicle and engine. Hyundai Australia currently publishes schedules that include both 10,000 km/12-month and 15,000 km/12-month intervals for different vehicles, showing why the exact service book should be checked rather than relying on a generic interval.
Major Car Service vs Basic, Minor and General Service
The easiest way to understand a major service is to compare its scope with routine servicing. Service names are not perfectly standard across every mechanic, so always check the actual inclusions rather than relying only on the label.
| Service type | Typical purpose | What to check |
| Basic/minor service | Routine maintenance and core checks | Oil, filter, fluid and inspection inclusions |
| General service | Routine maintenance with broader vehicle checks | Exact package scope and exclusions |
| Major service | More comprehensive scheduled maintenance | Manufacturer schedule and due replacement items |
| Logbook service | Maintenance to the vehicle manufacturer's scheduled requirements | Exact make, model, year and kilometre interval |
Mechanic Near You currently lists General Service from $129 and Logbook Service from $179. These are advertised starting prices for those services; a major service should be quoted against the vehicle's actual scheduled requirements rather than treated as a universal flat price.
For routine maintenance, you can view mobile car servicing or check the General Service before booking.
What Is Included in a Major Car Service?
A major service should be built around the manufacturer's scheduled maintenance requirements for your specific vehicle. Depending on the service interval, a comprehensive appointment may include several of the following areas.
1. Engine Oil and Oil Filter
The mechanic checks the required oil specification and replaces the engine oil and oil filter when due. The correct oil grade and quantity matter because different engines can require different specifications.
2. Fluid Checks and Scheduled Fluid Replacement
Brake fluid, coolant, transmission fluid, power steering fluid where applicable and other fluids may be inspected. Some are only checked at one interval, while others are replaced according to the manufacturer schedule.
3. Air and Cabin Filters
Air and cabin filters are inspected and replaced when the service schedule or condition requires it. Fuel filters may also be scheduled on some vehicles.
4. Brakes, Tyres and Suspension
A comprehensive service commonly includes inspection of brake components, tyre condition and pressure, suspension and steering components. Replacement of worn parts is normally a separate repair unless specifically included in the service package.
5. Belts, Hoses and Cooling System
Belts, hoses, cooling-system components and visible leaks may be inspected. Timing-belt replacement, where applicable, is a major scheduled maintenance item that must be checked against the manufacturer's interval rather than assumed to be due at every major service.
6. Battery and Charging System
The battery and charging system may be tested as part of the vehicle inspection. A battery replacement or alternator repair is normally an additional job unless the service package explicitly includes it.
7. Spark Plugs and Ignition Components
Petrol vehicles may have spark plugs scheduled for replacement at a particular interval. The exact interval varies by engine, so the mechanic should check the manufacturer's schedule before recommending replacement.
8. Diagnostic and Warning-Light Checks
Where included, a scan can help identify stored fault codes or electronic issues. A diagnostic scan does not automatically mean every fault will be repaired within the service price.
Major Car Service Checklist by Kilometre Interval
The table below is a planning guide, not a universal manufacturer schedule. Use it to understand the kind of maintenance that can become relevant as kilometres increase, then confirm the exact items in your vehicle's owner's manual or service book.
| Approx. milestone | Items that may become relevant | What to confirm |
| 10,000–15,000 km | Oil, oil filter, fluid checks, tyres, brakes and general inspection | Manufacturer interval and time limit |
| 20,000–30,000 km | Routine service plus filters, fluid checks and additional scheduled inspections | Which filters or fluids are due for your model |
| 40,000–60,000 km | Broader inspection and selected scheduled replacement items | Spark plugs, filters, fluids, belts or other scheduled items |
| 70,000–90,000 km | Recurring maintenance plus higher-interval replacement items where specified | Manufacturer's exact major-service checklist |
| 100,000–120,000 km | Comprehensive inspection and potentially significant scheduled maintenance | Timing system, transmission fluids, cooling system and other model-specific items |
| 150,000 km+ | Long-term maintenance items and condition-based repairs may become more relevant | Full service history and upcoming manufacturer intervals |
Why the ranges matter: manufacturer schedules can differ substantially. For example, current Hyundai schedules include different service intervals by vehicle and engine, and some published schedules list specific maintenance items at 30,000 km, 60,000 km, 90,000 km and beyond.
What Happens During a Major Car Service?
- Vehicle details are confirmed. Make, model, year, engine, kilometres and service history help identify the correct schedule.
- The service interval is checked. The mechanic identifies which manufacturer-scheduled items are due.
- Routine maintenance is completed. Oil, filters and other included maintenance items are carried out according to the agreed scope.
- Safety and condition checks are performed. Brakes, tyres, suspension, battery, belts, hoses, fluids and other relevant areas are inspected.
- Additional issues are identified. Wear or faults outside the scheduled service may be documented.
- Extra repairs are quoted separately. Where additional work is required, ask for the price and approval process before proceeding.
- The service record is completed. Keep the invoice and service documentation with the vehicle's maintenance history.
What Can Cost Extra on a Major Car Service?
A major service can uncover maintenance needs that are not part of the original service package. A transparent quote should separate the scheduled service from additional repairs.
| Possible extra | Why it may be separate | Question to ask |
| Brake pads or rotors | Wear item and repair rather than routine service labour | Can I get a separate repair quote? |
| Battery | Replacement depends on test results and condition | Is the battery healthy or does it need replacement? |
| Timing belt | Model-specific scheduled replacement | Is it due at this exact kilometre/time interval? |
| Spark plugs | Scheduled at different intervals by engine | What does the manufacturer schedule say? |
| Transmission fluid | Interval and specification vary by transmission | Is fluid replacement due and what specification is required? |
| Diagnostic repair | Finding a fault is different from repairing it | What fault was found and what is the repair price? |
Mechanic Near You states on its service pages that additional scheduled items are explained and quoted before extra work is carried out.
How Much Does a Major Car Service Cost?
There is no single major car service price that applies to every vehicle. The cost can change with the make and model, engine, kilometres, manufacturer schedule, oil and fluid specifications, parts and labour required.
Be careful with a generic “major service from $X” figure if the provider does not explain what is included. A major service is most useful when the quote is matched to your actual vehicle and service interval.
For context, Mechanic Near You currently advertises General Service from $129 and Logbook Service from $179. These prices should not be treated as a major-service price; they are separate advertised starting prices for the listed service types.

Signs Your Car May Be Due for a Major Service
The strongest sign is not a warning light — it is the scheduled maintenance interval. Check the owner's manual or service history first. Other clues can include:
- Your service reminder or service book shows a scheduled maintenance milestone is due.
- The vehicle has reached a higher kilometre interval with several scheduled items due together.
- You have incomplete or unclear service history and need the maintenance schedule reviewed.
- The car is showing maintenance-related symptoms such as unusual noises, fluid leaks or warning lights.
- You are buying or selling a used vehicle and want the maintenance history brought up to date.
A warning light or drivability problem should not simply be treated as “time for a major service”. It may need a separate diagnostic assessment.
Major Service When Buying a Used Car
If you have recently bought a used car and the service history is incomplete, a comprehensive inspection can help identify overdue maintenance. Ask the mechanic to review the available service records and compare them with the manufacturer's schedule.
This is different from a pre-purchase inspection. A pre-purchase inspection is focused on assessing a vehicle before you buy it, while a major service is focused on carrying out scheduled maintenance on a vehicle you already own or are maintaining.
If you are considering a vehicle before purchase, see the mobile pre-purchase car inspection service.

Major Service vs Logbook Service: Which One Do You Need?
These terms can overlap, but they should not be treated as identical automatically. A logbook service is tied to the manufacturer's scheduled maintenance requirements. A major service is commonly used to describe a more comprehensive service interval with additional maintenance items.
Your vehicle may have a major service that is also its scheduled logbook service. The correct choice depends on what the manufacturer's service schedule requires at your current time and kilometres.
Mechanic Near You offers mobile Logbook Service from $179 and states that its logbook servicing follows the manufacturer's schedule.
Questions to Ask a Mechanic About a Major Service
- Which exact manufacturer service interval is my vehicle due for?
- What parts, fluids and labour are included in the quoted service?
- Which scheduled items are due at this kilometre milestone?
- Are spark plugs, filters or transmission fluids due?
- Is timing-belt maintenance relevant to my engine?
- Is diagnostic scanning included?
- Will you inspect brakes, tyres, suspension and steering?
- What happens if you find a separate repair?
- Will you contact me before carrying out extra work?
- Will I receive an itemised invoice and service record?
How to Get an Accurate Major Car Service Quote
When requesting a quote, give the mechanic as much vehicle information as possible. A useful quote request should include:
- Make and model
- Year
- Engine type or variant
- Current kilometres
- Last service date and kilometres
- Service-book or owner's-manual information if available
- Any warning lights or symptoms
- Whether you need a scheduled logbook service
This gives the mechanic a better chance of matching the quote to the correct service interval instead of giving you a generic package price.

Can a Major Car Service Be Done by a Mobile Mechanic?
Many scheduled maintenance tasks can be completed at a suitable home or workplace location, but not every repair or major maintenance job is suitable for mobile servicing. The mechanic should confirm that the required work can be safely and properly completed onsite.
Mechanic Near You describes its services as mobile and says its mechanics travel to homes, workplaces and roadside locations across Melbourne.
If your vehicle's scheduled requirements fit the available mobile service, you can book a mobile car service and provide the vehicle details before the appointment.
Frequently Asked Questions
What is included in a major car service?
A major car service covers the scheduled maintenance items required at a particular service interval. Depending on the vehicle, this can include oil and filter replacement, fluid checks, filter replacement, brake and suspension inspections, spark plugs, belts, hoses, diagnostic checks and other manufacturer-specified items. The exact checklist varies by vehicle.
How often does a car need a major service?
There is no universal major-service interval. Your vehicle's manufacturer schedule may specify servicing by kilometres, months, or whichever comes first. Check the owner's manual or service book for the exact interval.
Is a major service the same as a logbook service?
Not always. A logbook service follows the manufacturer's scheduled requirements, while “major service” commonly describes a more comprehensive maintenance interval. In some vehicles the major service may also be the scheduled logbook service.
How much does a major car service cost?
The cost varies by vehicle, service interval, parts, fluids and labour. A proper quote should be based on your make, model, year and kilometres rather than a generic major-service figure.
What is usually changed in a major service?
Depending on the vehicle and interval, scheduled work can include engine oil and filter, air or cabin filters, spark plugs, fluids and other maintenance items. Some components are inspected rather than automatically replaced.
Is a timing belt included in a major service?
Only when the manufacturer's schedule says the timing belt is due and the service package includes that work. Timing-belt intervals vary by vehicle, so it should be confirmed against the manufacturer's schedule.
Can a mobile mechanic do a major car service?
Many scheduled maintenance tasks can be performed by a mobile mechanic at a suitable location. However, some jobs require workshop equipment or conditions, so the mechanic should confirm that your specific service can be completed onsite.
What should I do if my car is overdue for a major service?
Arrange an assessment using the vehicle's current kilometres and service history. Tell the mechanic how overdue the service is and provide the service-book information so the correct maintenance items can be identified.
Book the Right Major Car Service for Your Vehicle
A major car service should be based on your vehicle's actual maintenance schedule, not just a generic kilometre number. Before booking, confirm the exact interval, included parts and fluids, scheduled replacement items, inspection points and how additional repairs will be handled.
If your vehicle is due for scheduled maintenance, book a mobile car service with Mechanic Near You and provide your make, model, year and current kilometres so the correct service can be confirmed.
