PM Service & Oil Change

RT Group performs PM service and oil changes for trucks in Zion, IL — scheduled preventive maintenance, fluids, filters, and a full inspection checklist, with fleet PM programs available. Call (224) 588-3442.

PM Schedules & Intervals

Preventive maintenance (PM) service catches small issues before they become breakdowns. We follow mileage- and time-based intervals appropriate to your truck's use, adjusting for heavy-haul or short-regional duty cycles.

What's Included

  • Engine oil and filter change
  • Fluid checks and top-offs (coolant, DEF, transmission, differential)
  • Air, fuel, and cabin filter inspection/replacement
  • Multi-point inspection checklist (belts, hoses, leaks, wear items)
  • Brake and tire visual inspection

Fleet PM Programs

Fleets can set up a recurring PM schedule across multiple units so service happens on a predictable cycle instead of reactively — see our Fleet Service page for details.

Why RT Group

Built for Drivers Who Can't Afford Downtime

Catch problems before they're breakdowns

A thorough PM checklist finds wear items before they fail on the road.

Right fluids, right intervals

Service matched to your truck's actual duty cycle, not a generic schedule.

Fleet PM scheduling

Recurring service cycles across your whole fleet, not just one-off visits.

Same-visit fixes

Anything flagged on the inspection checklist can usually be quoted and fixed the same day.
