Minor vs Major Car Service: What’s the Difference?
Last updated: June 2026
You’ve just received a reminder that your car is due for a service, but which type? Minor or major? It’s one of the most common questions Australian drivers ask, and the answer affects both what happens to your car and how much you pay. This guide breaks it all down in plain language.
In short: a minor service is your routine maintenance check, oil, filters, and safety items. A major service goes deeper, replacing wear items and performing a full system inspection. Most cars need a minor service every 10,000–15,000 km and a major service every 30,000–40,000 km.
What Is a Minor Car Service?
A minor car service, sometimes called a basic or interim service, is a regular maintenance check focused on the most critical consumables. It keeps your vehicle running safely between major services and is typically done every 10,000–15,000 km or every 6–12 months, whichever comes first.

What Is a Major Car Service?
A major car service is a comprehensive inspection and maintenance procedure that addresses wear items your car accumulates over a longer period. It is typically recommended every 30,000–40,000 km or every 2–3 years, though your owner’s manual will specify the exact interval for your make and model.
Think of it this way: a minor service maintains what’s already there. A major service replaces components that degrade over time, spark plugs, belts, fluids, and filters that minor services only check.

How Often Do You Need Each Type?
- Minor service: Every 10,000–15,000 km or every 6–12 months, whichever comes first
- Major service: Every 30,000–40,000 km or every 2–3 years, whichever comes first
- Many manufacturers alternate: minor → minor → major → minor → minor → major
- Older vehicles (10+ years) benefit from minor services every 6 months regardless of km
If you’re unsure where you are in your service cycle, check your logbook. The last service entry will note whether a minor or major is next. No logbook? Ask your mechanic to check using your VIN.
How Does This Relate to a Log Book Service?
A log book service follows the specific schedule set by your car’s manufacturer, it’s the structured maintenance plan that protects your new car warranty. Minor and major services slot into that schedule. The key point: any licensed mechanic can stamp your logbook, you don’t need to visit a dealership. Under Australian Consumer Law, your warranty is protected as long as the service meets manufacturer specifications and is properly recorded.
