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.

“I’ve been to a lot of shops, and RT Group is one of the few that actually does what they say. Rolled in with an issue on my trailer — no lights, busted wire. They got me in quick, showed me exactly what was wrong, and had it fixed that same day.”

“Brought my Freightliner Cascadia to RT Group after an air leak and brake issues. The mechanics found the problem quickly, explained what needed to be repaired, and got the truck back on the road the same day. No guessing, no unnecessary work, no surprise charges.”

“Great people working. Very professional and do quality work. We came in for some electrical issues on the trailer after another road service made a big mess there. They found the problem and fixed it quickly. Highly recommend this place.”
