Preventive Maintenance Schedules That Actually Cut Downtime

Reactive Repairs Cost More Than Maintenance Does

Every fleet manager has run the numbers at some point: an unplanned roadside breakdown doesn't just cost the repair bill, it costs the missed delivery, the detention fees, and the driver sitting idle on the shoulder. A well-built preventive maintenance (PM) schedule is still the cheapest insurance policy your fleet has.

What a Real PM Schedule Includes

A schedule based only on mileage misses a lot. We build PM intervals around a mix of mileage, engine hours, and calendar time, and they typically include:

  • Oil and filter changes tied to duty cycle, not just a flat interval
  • Brake, tire, and wheel-end inspections at every service visit
  • Fluid analysis to catch internal wear before it becomes a failure
  • DOT-required inspection items checked proactively, not just annually

The goal is to find the $200 problem before it becomes the $4,000 problem — or the truck stranded 200 miles from home.

Building a Schedule Around Your Fleet

No two fleets run the same routes, loads, or duty cycles, so we build PM plans specific to how your trucks and trailers are actually used. A regional tanker fleet and a long-haul dry van fleet need different intervals, different fluid specs, and different inspection priorities.

If your fleet is still running maintenance reactively, we can put together a PM schedule that fits your routes and your budget — and start closing the gap between what breaks and what gets caught first.
