1. What Is Preventive Fleet Maintenance?
Preventive maintenance involves scheduled inspections.
This includes:
-
Regular oil and filter changes
-
Brake inspections and replacements
-
Tire rotations and pressure checks
-
Battery tests
-
Engine diagnostics and fluid top-ups
-
DEF & DPF system cleaning
These proactive measures ensure your vehicles remain in top shape, avoiding unexpected issues on the road.
2. The Cost of Ignoring Maintenance
Skipping or delaying maintenance may seem like a way to save money—but it often results in:
-
Major repairs: A neglected engine or transmission can lead to $5,000–$10,000 in repair costs.
-
Downtime: Every hour a truck is off the road equals lost productivity and missed deliveries.
-
Fines: Safety violations during inspections due to worn tires or faulty brakes can lead to hefty DOT fines.
-
Shorter vehicle lifespan: Poorly maintained trucks often fail before reaching optimal mileage.

Tire inspections: Monthly
-
Brake system checks: Every 20,000 miles or as needed
-
Full inspection & diagnostics: Quarterly
Using telematics or fleet management software can help you automate service reminders and track history.
