What’s better for your car: Major service infrequently or Minor service frequently? 

The Real Question Every Driver Faces

Every driver wants their car to last, but few agree on how often it should be serviced. Some swear by a minor service every six months. Others wait for a “major” service once every year or two. The truth lies somewhere between, depending on how and where you drive.

Servicing is about prevention. Regular attention keeps oil clean, fluids fresh, and small faults from turning into expensive failures. Skipping or stretching intervals might seem to save money, but it quietly shortens your car’s lifespan.

Manufacturers design their schedules to protect every major component, not to sell more services. These intervals are tested under thousands of hours of use, so ignoring them means taking chances with the reliability and value of your car.

What a Minor Service Covers and Why It’s Worth Doing Often

A minor service is the most frequent form of maintenance. It keeps your car’s vital systems running efficiently between major inspections.
Typical inclusions:
  • Engine oil and oil filter replacement
  • Fluid top-ups (brake, coolant, power steering, washer)
  • Battery, tyre, and wiper checks
  • Visual inspection of belts, hoses, and exhaust
  • Road test and safety assessment
Minor services take about one to two hours. They catch small issues like oil leaks or uneven tyre wear before they escalate.
Why minor services matter:
  • Fresh oil reduces friction and extends engine life
  • Regular inspections keep safety systems working
  • Technicians can identify developing faults early
When it’s not enough:
If your car has done over 40,000 km, missed its last major service, or shows warning lights, a minor check will not reset its maintenance cycle. At that point, deeper servicing is required.

What Makes a Major Service Different

A major service goes beyond routine maintenance. It’s the deep reset that keeps your car healthy for years.

It typically includes:
All minor service items
Spark plug and fuel filter replacement (where applicable)
Brake fluid and coolant flush
Air and cabin filter replacement
Transmission oil change (if due)
Suspension, steering, and drive belt inspection
Full diagnostic scan and software updates
The goal is to restore your car to peak condition, replacing components that degrade with time, not just kilometres.

Modern cars have complex electronics that require periodic recalibration. Chandos Autos uses professional scan tools to identify and clear hidden faults that basic services miss.

Major vs Minor: Which Is Better and When?

Neither service type is better — they serve different purposes. Think of them as a team:
  • Minor services keep your car clean, lubricated, and safe in the short term.
  • Major services reset critical systems and prevent expensive repairs.
The worst mistake is skipping both or relying on one alone. Waiting until the car “feels off” usually means it’s already too late.
Common myths:
  • “My car runs fine, so I don’t need a major service.”
    Hidden wear often doesn’t show symptoms until failure.
  • “I’ll just do minor services more often.”
    Fluids like coolant and brake fluid degrade chemically, not by kilometres alone.
  • “It’s cheaper to skip one and catch up later.”
    Missed services often cost more in repairs than they save.

How to Balance Service Frequency and Cost

Servicing too infrequently risks expensive failures. Servicing too often wastes time and money. The best approach is consistency — alternating minor and major services according to your logbook.
For most Australian drivers:
  • Minor service every 10,000–15,000 km or 6 months
  • Major service every 40,000–60,000 km or 24 months
City driving: Frequent short trips don’t allow oil to reach full temperature, so contaminants build faster. Stick to the shorter end of each interval.

Highway driving: Longer trips are easier on engines, so you can safely follow the upper range.

Hidden savings:
  • Fewer major repairs over the life of the vehicle
  • Better fuel economy
  • Higher resale value
  • Continuous warranty protection
According to the RACV, vehicles with consistent servicing can retain 8–10% more resale value than those with irregular maintenance.

Checklist: Is Your Car Overdue for More Than a Basic Service?

Ask yourself these questions before your next booking:

  • Has it been over two years or 40,000 km since your last major service?
  • Do you have records for your last coolant or brake fluid change?
  • Have you noticed reduced fuel economy or sluggish performance?
  • Are there any dashboard lights or unusual noises?
  • Has your service book skipped any pages?
If you answered “yes” to one or more, your car likely needs more than a minor check.

FAQs

Over time, yes. Minor services don’t replace fluids or parts that age chemically, like coolant or brake fluid. Skipping major services risks internal damage.

Even low-mileage cars need yearly checks because fluids degrade and seals dry out.

They include more labour, fluids, and part replacements. However, they prevent far more expensive breakdowns.

Chandos uses OEM-grade parts and approved equivalents that meet or exceed manufacturer standards.

Mechanic services a modern car with an open service booklet in the foreground.

You ring up to book a service and the first thing you are asked is which one you want. Nobody explains the question, so most people guess. The short answer is that a logbook service follows the list your manufacturer wrote, a standard service follows the workshop’s own, and which you need comes down mostly to whether the car is still under warranty.

Mechanic examines a front brake caliper and disc on a raised car.

You get out of the car after a short trip and something smells hot. One wheel is far warmer than the others, but the brake pedal feels exactly as it always has. That combination usually points at a sticking brake caliper, and it will eat a set of pads and a disc while the pedal keeps telling you everything is fine.

Mechanic showing a customer a job sheet at the service counter

You booked a service, and at the counter you were told the car would benefit from an engine flush or a fuel system clean on top. Neither one is scheduled maintenance, and a car serviced on time usually needs neither. Here is what each job involves, when it earns its money, and the three questions worth asking before you say yes.

As a woman who isn't particularly knowledgeable about cars (personally), I've unfortunately had some bad experiences in the past where I felt taken advantage of. That's why I am so incredibly grateful to have found Chandos Auto's! From the moment I walked in, Sarah and Paul were not only welcoming but also transparent with their pricing. They took the time to explain exactly what needed to be done to my car, why it was necessary, and what the costs would be upfront. Their kindness, honesty, and professionalism made me feel confident in their work, and I can’t express how much peace of mind it gives me to know I have a mechanic I can trust and now have as my regular mechanic. I wholeheartedly recommend Chandos Auto's to anyone looking for reliable, honest car service. Thank you again, Sarah and Paul! My car is running beautifully. :)

Very friendly, knowledgeable and professional. Explained the work that they performed on my car to me and answered any questions I had. No hidden costs along the way, as I was called and asked prior to anything unexpected being done so I could decide how to proceed. Thank you, I will be returning next service.

I can’t say enough good things about these folks!! I had one day to get 3 days worth of stuff done and they smashed it for me cheaper than I was quoted else where. And they did it while being extremely kind and polite.

Life had thrown massive curveballs and to top it off, I had my elderly fathers car transferred into my name. Original mechanic sick, booked in a panic to another who did not turn up. Last day to keep registration ( I had been waiting for original mechanic- my fault). I rang Chandos and these guys squeezed us in. They were already busy. They were kind, professional, upfront and honest. I will definitely go back to these guys. Very happy. A massive Thankyou
