1. Protecting Vehicle Reliability & Safety.

Once a vehicle crosses 100,000 km, key components (fluids, belts, suspension, sensors) start aging faster.

• Oil and fluids degrade faster: Older engines accumulate more carbon and contaminants, making clean oil more important. Six-month intervals reduce sludge buildup and keep seals lubricated.
• Wear items fail unpredictably: Suspension bushes, steering joints, and brake components wear at different rates after 100,000 km. Regular checks catch issues before they become breakdowns or safety hazards.
• Tyre & brake health: Six-monthly service ensures tyre rotation and brake inspections line up with real-world wear patterns, which are rarely in sync with 15K–20K manufacturer intervals.

2. Preventing Expensive Repairs.

Many big-ticket failures are preventable with more frequent inspections:

• Cooling system leaks: Catching a small coolant seep early can prevent a head gasket or engine overheat job later.
• Timing belt & accessory belt checks: More touchpoints mean you’ll spot cracks, tension issues, or leaks near the belt path before they destroy the engine.
• Battery & charging system: Avoids the “no-start” surprise — particularly relevant for rideshare drivers, tradies, and busy parents.

The cost of one missed failure (e.g. overheating leading to engine replacement) dwarfs the extra service cost.

3. Real-World Driving vs. "Ideal Conditions".

Manufacturer schedules are based on ideal operating conditions (steady highway driving, mild climate).

• Australian reality: Stop-start traffic, summer heat, towing, dust, and short trips all count as severe service — which actually shortens service intervals in the fine print.
• City driving stress: After 100,000km run, injectors, EGR valves, and DPF systems get dirtier faster. More frequent servicing helps manage buildup and reduce engine light problems.

4. Resale Value & Customer Peace of Mind

• Better resale story: A logbook that shows servicing every 6 months rather than “just when required” gives confidence to the next buyer — higher resale price.
• Predictable budgeting: Smaller, regular service bills are easier to manage than irregular large repairs.
• Customer reassurance: Knowing that your car is inspected twice a year — can lead to fewer roadside surprises, safer family transport. Or you can DIY your car and call the tow truck or the mechanic when you are introuble, which ever you think that can save you money. 

The 100,000 km “Trap” – What Dealers Don’t Tell You

Car salespeople and used-car buyers often use the 100,000 km mark as a psychological and pricing milestone.

• Depreciation Cliff: Many vehicles drop in resale value once they tick past 100,000 km. Buyers see it as the “end of the car’s prime life,” even if the car is in excellent condition.
• Service History Becomes Critical: After 100K, buyers look closely at the service logbook. A car with 6-monthly servicing after 100K km can fetch a much higher resale price compared to one that just follows the stretched manufacturer schedule.
• Dealer Advantage: Some dealers want you to neglect post-100K servicing so they can buy your car cheap, fix it up just enough, and resell at a profit.
