Handbook service schedules are written for average conditions. Zambian work vehicles — dust, heat, heavy loads, corrugated gravel roads, long idling — live in what manufacturers call "severe conditions", and the handbook itself usually specifies shorter intervals for exactly that. Few owners read that page.
A practical severe-conditions schedule
- Engine oil & oil filter: every 5,000 km (diesel work vehicles), even where the handbook allows 10,000 km
- Air filter: inspect every 5,000 km, replace every 10,000–20,000 km depending on dust — a clogged filter costs power and fuel
- Fuel filter (diesel): every 10,000–20,000 km — local diesel quality makes this non-negotiable
- Brakes: inspect every 10,000 km; loaded vehicles and highway runs wear pads fast
- Suspension bushes and shocks: inspect every 20,000 km on vehicles that regularly see gravel
- Gearbox, diff and transfer oils: every 40,000 km for work 4x4s
- Timing belt (where fitted): strictly per handbook, typically 100,000 km — a snapped belt destroys engines
Track it by vehicle, not by memory
Fleets that service "when someone remembers" pay for it in breakdowns during the busiest season. Every vehicle needs its own next-service date, and someone — or something — needs to watch it.
Aurevant fleet clients get exactly that: every vehicle digitised from its registration book, a fixed price list per vehicle, and automatic email alerts a week before each service falls due. Ask us about fleet service management for your operation.
