Major vs Minor Car Service: Key Differences and Complete Checklists for Both

Car maintenance is essential for ensuring that your car remains in optimal condition and functions efficiently. Regular servicing is not only essential for the longevity of your car, but it also helps to prevent unexpected breakdowns and expensive repairs. Two common types of car services are major car service and minor car service. Both services are important, but they differ in terms of what’s included and how often they are needed.

In this blog, we have explained the difference between major and minor car services in detail. We have covered what each service entails and the differences between the two, and provided you with comprehensive checklists so you can make sure your car gets the care it needs at the right time.

What Is a Minor Car Service?

A minor car service is a basic, routine maintenance service generally carried out every 10,000 to 15,000 kilometres, or around 6 months. It is designed to ensure that your car remains safe, reliable, and efficient between more comprehensive major services.

Basic Inclusions in a Minor Car Service Checklist

Here are the essential things commonly included in a minor car service checklist:

  • Engine Oil & Filter Change: Drain old oil and replace it with fresh oil; replace the oil filter to maintain smooth engine operation.

  • Fluid Top-Ups: Check and top up essential fluids like brake fluid, coolant, windscreen washer fluid, and transmission fluid.

  • Tyre Pressure & Rotation: Ensure correct tyre pressure for better fuel efficiency and even tyre wear through rotation.

  • Brake Check (Visual): Inspect brake pads, discs, and fluid levels for visible issues.

  • Battery Test: Test battery voltage and condition; replace if nearing the end of its life.

  • Basic Diagnostic Scan: Perform a quick scan to detect any minor faults in the engine or electrical system.

A minor car service is essential for maintaining your car’s reliability. If you’re looking for a minor car service near you, always ensure that the workshop follows your car's manufacturer recommendations and uses quality parts.

What Is a Major Car Service?

A major car service is more comprehensive and typically takes place every 30,000 to 45,000 kilometres, or 12 months, depending on your car's usage. This service includes everything in a minor service but also goes deeper into various systems of the car to ensure they are in top working condition. It helps prevent more serious problems from developing by addressing issues that may not be immediately apparent.

Key Inclusions in a Major Car Service Checklist

A major car service checklist is extensive and addresses the following key areas:
 

  • Air Filter Replacement: Replace the air filter for clean, dust-free air to improve engine performance and longevity.

  • Cabin Filter Replacement: Replace the cabin filter to ensure clean, pollutant-free air inside the car, especially in urban areas.

  • Spark Plugs Replacement: Replace worn spark plugs to maintain engine performance, prevent poor fuel efficiency, and avoid starting issues.

  • Brake System Service: Inspect brake pads, rotors, fluid levels, and system functionality to ensure safe and efficient braking.

  • Transmission Check/Fluid Flush: Flush or inspect transmission fluid for smooth shifting and to prevent future transmission problems.

  • Cooling System Check: Check the radiator, hoses, and coolant levels to prevent engine overheating.

  • Suspension System Check: Inspect the suspension system, including shocks and struts, to ensure a smooth ride.

  • Full Diagnostic Scan: Perform a complete scan of the engine and electrical systems to detect hidden issues.

A major car service is important for maintaining the overall condition of your car and preventing breakdowns. A well-maintained car performs better, lasts longer, and retains more of its value.

Major vs Minor Car Service

To better understand the difference, let's take a look at the comparison between the two services.

Cabin Filter Replacement Not typically replaced, only checked for blockages. Replaced to maintain clean air inside the cabin.
Spark Plugs Replacement Not usually replaced. Replaced to ensure optimal engine performance and fuel efficiency.
Transmission Service Not included, but inspected visually. Full transmission fluid flush or inspection to ensure smooth shifting and prevent failure.
Battery Test Battery checked for charge level and condition. Comprehensive battery test, including checking the health of the electrical system and connections.
Diagnostic Scan A basic scan to detect any immediate issues. A comprehensive scan of the engine and electrical system to identify any underlying problems.
Tyre Rotation & Pressure Tyres rotated and pressure checked to ensure even wear. Tyre rotation and pressure check with additional assessments on wear and tread depth.
Cost Range More affordable due to the shorter list of tasks. More expensive due to the extensive checks and part replacements involved.

How Often Should You Service Your Car?

The service intervals can vary depending on your car’s make and model, as well as your driving habits. Here’s a general guide:

  • Minor Car Service: Every 10,000 to 15,000 km or 6 months, whichever comes first.
  • Major Car Service: Every 30,000 to 45,000 km or 12 months.

However, if you drive your car under harsh conditions (such as frequent short trips, towing, or driving in heavy traffic), you may need to service your car more frequently. Always check your car’s owner manual for specific recommendations and consult with a car mechanic in Melbourne for more tailored advice.
