🔎 Quick Fact
Many high-utilisation Australian fleet trucks cover more than 150,000 km a year, yet distance alone is a poor guide to when oil should be changed. What matters far more is the duty cycle, the combination of load, idle time, temperature swings, and stop-start patterns that determines how hard the oil actually works. Kilometres are like counting laps without checking the track surface; the real story is in the conditions each lap imposes.

🧭 The Story
A long-haul truck cruising at steady speed on the Hume Highway places very different demands on its oil compared to a distribution truck navigating city traffic with frequent braking and cold starts. Idle time generates soot without the combustion temperatures needed to burn it away, while repeated thermal cycling accelerates additive depletion. Two trucks on the same fleet can reach 150,000 km with vastly different oil conditions, even if both run the same product. For blenders, this means formulating to a single drain target risks either over-servicing one truck or under-protecting another.

🧠 What It Means
When blenders understand the specific duty cycles their customers’ fleets encounter, they can tailor drain interval guidance and select additive systems that match real operating stress. Checking the track surface, not just counting laps, helps formulators recommend with greater confidence and deliver lubricants that protect where it counts.
