How Often Should You Service Your Car? The Complete Guide

How often should you service your car? It's one of those questions that sounds simple — until you get a different answer from every person you ask. Your neighbour says every six months. The dealer says follow the logbook. Your mate who "knows cars" hasn't had a car service in two years and reckons it's fine.
Here's the straightforward answer — and what actually happens when you stick to the schedule (or don't).
🔧 The General Rule — Every 6 Months or 10,000 km
For most cars, the standard recommendation is a service every 6 months or 10,000 kilometres — whichever comes first. Some newer models have pushed this out to 12 months or 15,000 km, but that's the exception rather than the rule.
The "whichever comes first" part trips people up. If you've only driven 4,000 km in six months, you still need a service. Oil degrades over time regardless of whether you're driving, seals dry out, and moisture builds up in the engine. Time matters just as much as distance.
Your owner's manual or logbook will have the manufacturer's recommended intervals for your specific car. If you're not sure, a logbook service based on your make and model will keep everything on track.
📋 What Can Change Your Car Service Schedule?
The standard intervals assume fairly normal driving conditions. If any of these apply to you, your car might need more frequent attention.
Stop-start driving
Constant city traffic, short trips, and idling are harder on your engine than highway cruising. The engine doesn't get to operating temperature as often, which means more moisture and contaminant build-up in the oil.
Dust, gravel, and rural roads
If you're regularly driving on unsealed roads — pretty common out here in regional Victoria — your air filter and oil get dirtier faster. Dust is an engine's worst enemy.
Towing and heavy loads
Regularly towing a caravan, boat trailer, or heavy loads puts extra stress on the engine, transmission, brakes, and cooling system. If towing is part of your routine, shorter service intervals are worth it.
Older vehicles
Cars with 150,000+ km on the clock generally benefit from more frequent oil changes and closer inspection. Things wear out — it's not a reflection on the car, it's just physics.
Diesel engines
Diesel servicing often has different intervals and requirements compared to petrol. Fuel filter changes, DPF maintenance, and injector care all factor in. If you're running a diesel, make sure your mechanic knows the specifics — or check out our guide to diesel engine servicing.
⚙️ Minor vs Major — What's the Difference?
Not every car service is the same. Most manufacturers alternate between minor and major services.
A minor service covers the essentials — oil and filter change, fluid level checks, a visual inspection of key components, and a basic safety check. It's the routine maintenance that keeps everything ticking over. You're generally looking at $200–$350 depending on the vehicle.
A major service includes everything in a minor service, plus deeper work like spark plug replacement, air and fuel filter changes, brake inspection, coolant system check, and transmission fluid assessment. These are more thorough and typically run $400–$700+, depending on the make and model.
The exact schedule varies by manufacturer, but a common pattern is minor–minor–major, repeating through the life of the car. Your logbook will spell out exactly what's due at each interval.
One thing worth knowing: getting your car serviced at an independent mechanic rather than the dealer won't void your warranty, as long as the work follows the manufacturer's specifications and genuine or equivalent parts are used. That's protected under Australian Consumer Law.
🚨 What Happens If You Skip a Car Service?
Skipping one service probably won't cause your engine to explode. But each missed service compounds the problem, and eventually something gives.
Oil breaks down. Old oil loses its ability to lubricate and protect. Metal-on-metal contact inside the engine causes wear that's expensive to fix and impossible to reverse.
Filters clog. A blocked air filter reduces fuel efficiency and performance. A neglected fuel filter can starve the engine. Neither is expensive to replace during a service — both are expensive to ignore.
Small problems become big ones. A service is also an inspection. Worn brake pads caught early are a $200 job. Left until the rotors are damaged? Now you're looking at $600+. A slow coolant leak caught at a service is a quick fix. Left until the engine overheats? That's potentially thousands.
Warranty and resale take a hit. An incomplete service history can void your manufacturer's warranty and will knock thousands off your car's resale value. Buyers and dealers both check.
The service schedule exists for a reason — it's the cheapest way to keep your car reliable, safe, and holding its value.

❓ Frequently Asked Questions
Q: Will servicing at an independent mechanic void my warranty?
A: No. Under Australian Consumer Law, you can have your car serviced at any qualified mechanic without voiding the manufacturer's warranty — as long as the service meets the manufacturer's specifications and appropriate parts are used.
Q: How much does a car service cost?
A: A minor service typically costs $200–$350 and a major service $400–$700+, depending on your vehicle. European and luxury cars tend to sit at the higher end due to parts and specialist requirements.
Q: What's included in a standard car service?
A: A standard minor service usually includes an oil and filter change, fluid top-ups, tyre condition and pressure check, battery test, brake inspection, and a general safety check of key components.
Q: Can I service my car less often if I don't drive much?
A: You should still service based on time intervals (usually every 6 months) even if you haven't hit the kilometre threshold. Oil degrades, seals dry out, and batteries lose charge — all of which happen regardless of how much you drive.
Q: How do I know when my car is due for a service?
A: Check your logbook or owner's manual for the manufacturer's schedule. Most cars also display a service reminder on the dashboard. If you're not sure, a mechanic can check your service history and let you know what's due.
