The most common service interval question Perth mechanics hear is: "How often do I actually need to bring my car in?" The answer depends on your vehicle — but here's the practical guide.
Standard Service Intervals
Most modern vehicles specify one of these service intervals:
- Every 10,000km or 12 months — common for Japanese and Korean brands
- Every 15,000km or 12 months — common for newer vehicles with synthetic oil
- Every 20,000–25,000km or 24 months — some premium European vehicles with long-life servicing
- Always follow the "whichever comes first" rule for time vs distance
How Perth's Heat Affects Service Intervals
Perth's extreme summer temperatures — regularly exceeding 40°C — put additional stress on engine oil and cooling systems. Conventional oil degrades faster in high-heat conditions. If you're using conventional (non-synthetic) oil and your car operates in Perth summer conditions regularly (particularly stop-start city driving in summer), consider servicing at the shorter end of your interval range.
Synthetic oil is significantly more heat-stable and is specified by most manufacturers for vehicles made in the last 10 years. If your mechanic recommends synthetic oil, this is one of the reasons why.
Check Your Logbook First
Your manufacturer's service logbook is the authoritative source for your specific vehicle's requirements. Look for the service schedule section — it lists the interval and what's included at each service point. If you've lost your logbook, your vehicle's VIN can be used to look up the manufacturer's schedule.
