A useful ownership plan separates predictable maintenance from uncertain repairs and uses the exact model-year schedule rather than a generic diesel interval.
Build the schedule
Start with the owner's manual and documented history. Track engine oil, fuel filters, air filters, cooling system, transmission, transfer case, axles, brakes and emissions-system service.
Match maintenance to duty
Towing, idling, dust, short trips, cold weather and commercial use can justify different inspection or service intervals.
Keep evidence
Record date, kilometres, parts and fluids. Good documentation helps diagnose future concerns and may improve buyer confidence when selling.
