Fleet PM Interval Guide — what schedule fits your fleet.

There is no single correct PM interval: the right schedule depends on your routes, load weights, and how much you want to gamble between inspections.

Kilometre-based intervals

Light-duty route (local delivery): PM every 15,000-20,000 km
Highway fleet (long-haul): PM every 25,000-40,000 km
Severe service (heavy loads, gravel roads, frequent stopping): PM every 15,000 km
Always align PM intervals with your annual inspection expiry to avoid gaps

Engine hour meters are more accurate than odometers for PTO and idle-heavy trucks
Common interval: every 250-500 engine hours (depends on duty cycle)
Mixing kilometre and hour-based trucks? Service on whichever comes first
