AI scheduling via TruView." canonical: https://www.helloslick.com/services/preventive-maintenance lastmod: 2026-06-24 --- # Preventive Maintenance That Keeps Your Fleet on the Road Oil changes, filters, fluid checks, tire rotations — on schedule, on-yard. Prevent small issues from becoming expensive failures. Full visibility through TruView. This is at the core of Slick's managed service. - [Get Pricing](https://www.helloslick.com/pricing) - [Book a Discovery Session](https://www.helloslick.com/demo) ## Why Waiting Costs You More Routine maintenance today prevents expensive failures tomorrow. Reactive maintenance is always more expensive than preventing the problem. - **Engine Damage** — A missed oil change leads to engine damage that costs 100x more to fix - **Tire Blowouts** — Skipped tire rotations cause uneven wear and blowouts on the road - **Failed Inspections** — Deferred maintenance means failed DOT inspections, fines, and liability - **Lost Revenue** — Every breakdown means a driver sitting idle and revenue walking out the door ## What Preventive Maintenance Covers Organized by frequency. Every item tracked and documented in TruView. You set the frequency. Whether it's a DOT inspection every month or the plan outlined below, you're in control. ### Monthly - Visual fluid checks - Tire pressure and tread inspection - Light and wiper inspection - Battery test ### Quarterly - Oil and filter change - Brake pad and rotor inspection - Air filter check - Coolant level and condition ### Semi-Annual - Fluid flushes — transmission, coolant - Belt and hose inspection - Alignment check - Undercarriage inspection ### Annual - Full DOT inspection - Transmission fluid flush - Brake fluid flush - Deep electrical diagnostic ## Vacuum-Based Oil Handling. No Hand Pouring. Our service vans use a fully vacuum-based oil system. Used oil is sucked directly into sealed waste tanks. Fresh oil is dispensed directly from onboard bulk tanks into your vehicles. No funnels. No jugs. No hand pouring. The result: faster service, zero spill risk, and full accountability for every drop of oil — in and out. It is the safest, most efficient way to handle oil changes at scale. - **Vacuum Extraction** — Used oil is suctioned directly into sealed waste tanks on our vans. No drain pans, no mess. - **Direct Dispensing** — Fresh oil flows from onboard bulk tanks directly into your vehicles. Precise volume, every time. - **Environmentally Conscious** — Sealed system from start to finish. No spills on-yard, no contamination risk, no waste. ## Dedicated Tire Box Trucks. Full Mount and Balance On-Site. Our tire box trucks carry state-of-the-art tire mounting and balancing equipment — the same quality you would find in a dedicated tire shop, deployed directly on-yard. Mounting, balancing, rotation, and replacement without sending a single vehicle off-site. One truck, one shift, 25+ tires changed. Your fleet stays on your lot, your drivers stay on the road, and you skip the scheduling nightmare of shop appointments. - **Purpose-Built Box Trucks** — Dedicated tire service trucks equipped with commercial-grade mounting and balancing machines. A mobile tire shop at your yard. - **Full Mount & Balance** — Same precision equipment as a tire shop. Mounting, dismounting, balancing, rotation, and replacement — all on-site. - **25+ Tires Per Shift** — High throughput means your entire fleet gets handled in a single visit. No staggered shop appointments across weeks. ## How Preventive Maintenance Works Four steps. Fully automated. Nothing falls through the cracks. ### 1. Schedule TruView auto-schedules preventive maintenance based on actual vehicle mileage and manufacturer specs. ### 2. Arrive Slick technicians arrive on-yard in custom service vans — nights, weekends, whenever works for you. ### 3. Service Oil, filters, fluids, tires, brakes — whatever's due gets handled on-site. Up to 10 vehicles per visit. ### 4. Document Every service is logged in TruView with photos, technician notes, parts replaced, and next service date. ## The ROI of Prevention Every dollar spent on prevention saves multiples in emergency repairs, downtime, and lost revenue. - **Extended Vehicle Life** — Regular maintenance can add years to a vehicle's useful life, reducing total cost of ownership across your fleet. - **Better Fuel Efficiency** — Well-maintained vehicles use less fuel. Clean filters, proper tire pressure, and fresh fluids add up across a fleet. - **Reduced Unexpected Downtime** — No roadside breakdowns. No emergency towing. Drivers stay on schedule because problems are caught early. - **Lower Insurance & Compliance Costs** — Proper maintenance means cleaner inspection records, which can mean lower insurance premiums. - **Higher Resale Value** — Fleets with full, documented service history command higher resale prices when it's time to turn over. ## Real Results: HVAC Service Fleet This fleet in the Southeast was losing billable time to shop visits and emergency repairs. A "quick" oil change meant a half-day round trip, and two ProMasters needed emergency rotor replacements from missed brake pad wear. - **100%** — Shop visits eliminated. All work done on-lot overnight. - **Over $45,000** — Recaptured revenue per year. Half-days lost to shop trips, turned back into billable service calls. - **Down 80%** — Emergency repairs. Wear caught at scheduled PM instead of on the side of the road. - **1 hr/week** — Owner management time. Down from 4-6 hrs/week — now a weekly TruView review. Started with managed maintenance covering oil, inspections, and brakes for all 15 vehicles. Within 90 days added tires and corrective repairs. Service after hours at their lot — trucks ready by morning. First visit: Slick tech serviced 8 vehicles, completed 4 oil changes, flagged 1 for brake pads. > "Slick has been an absolute game changer for us. We appreciate your team and service so much." > — Fleet Owner ## Heavy-Duty PM Runs on Tiers. Heavy Duty — Class 7–8 The PM described on this page is built for light and medium duty. For Class 7–8, the work splits into Slick HD PMI tiers — and the tiers nest. PMI-A is the minor service — lube, oil, and filter plus a 91-point inspection. PMI-B is the major service, a 105-point superset of PMI-A. Dry is the entry tier: a tractor-only health check with no fluid service, and every PMI includes its full 75-point inspection. Brakes are measured on all three — pushrod stroke and lining, every axle — and every result lands in TruView. [See Slick HD PMI](https://www.helloslick.com/services/hd-pmi) ## Preventive Maintenance FAQ ### How often should I service my fleet? It depends on mileage and vehicle type. Most fleets on a 5,000-mile interval see the best results. TruView tracks actual mileage and schedules automatically. ### What's the difference between preventive and managed maintenance? Preventive maintenance is one component of Slick's managed service. The managed service includes PM plus inspections, repairs, and everything else — all under one monthly program. ### Do you track DOT DVIR requirements? Yes. TruView maintains digital inspection records, tracks compliance status per vehicle, and keeps your fleet audit-ready year-round. ### What if a vehicle fails inspection during PM? Issues found during preventive maintenance get flagged in TruView. If it's in your managed service, we fix it. If not, you get an estimate for approval. ### Can I adjust maintenance frequency for newer vehicles? Absolutely. TruView customizes schedules per vehicle based on age, mileage, manufacturer specs, and your preferences. ## Related Services Preventive maintenance is the foundation.
