How often should fleet vans get an oil change?

GTA fleet duty is severe service, full stop — stop-and-go routes, idling, short trips, loads. That means the severe-service column of your platform's schedule, not the marketing interval. As a working rule that means oil service noticeably more often than a commuter car — set per platform and duty cycle, then locked per unit. The exact interval for each van gets set from its OEM severe-service table at the yard assessment, then tracked so it actually happens.

Why do loaded vans eat brakes so fast?

Weight and duty cycle. A van running at or near GVWR with a courier stop-start pattern works its front brakes constantly, so pads that would last years on a commuter car can be gone in well under a year of route work. The money move is measuring pads and rotors at every PM visit — catching them at pad-swap price instead of pads-rotors-and-a-seized-caliper price.

What kills work vans besides brakes?

Front-end wear (ball joints, tie rods, sway-bar links — constant load plus GTA potholes), batteries and charging systems (liftgates, telematics, chargers and short trips chronically undercharge them), cooling systems on idle-heavy trades vans, and tires that wear unevenly when alignment drifts under load. All of it is inspectable — which is why a real PM visit is an inspection with an oil change attached, not just an oil change.

Do diesel vans need a different PM approach?

Yes. Euro diesel platforms carry bigger sumps with specific oil approvals, fuel filter service matters more, DEF systems need topping and attention, and emissions hardware hates the exact duty cycle couriers run (short trips, idling). Diesels in stop-start fleet duty need their maintenance taken more seriously, not less — skipping intervals on a modern diesel gets expensive fast.

The van fleet PM schedule that actually works (Sprinter, Transit, ProMaster, box trucks)

By Fares · Mobile fleet mechanic, Mississauga · Updated July 2026 · From yard experience, not a content farm

Every van in your fleet came with a maintenance schedule. Almost none of them are being followed — because OEM schedules assume a polite commuter life, and your vans live a completely different one: loaded to the roof, stop-start all day, idling at job sites, short-tripping between drops. In maintenance terms, every working fleet van in the GTA is on "severe service" duty, and the schedule that works is built from the duty cycle, not the marketing brochure.

Here's how I build PM schedules for the fleets I service — by duty cycle first, platform second, then locked per unit.

Step 1: know which fleet you actually run

Courier / last-mile (Sprinters, Transits, ProMasters, cargo vans): huge annual mileage, brutal stop-start, hundreds of brake applications a day, doors and idling cycles all shift. Killers: brakes, oil intervals that slip, batteries, front ends.
Trades (plumbing, HVAC, electrical vans; pickups): moderate mileage but heavy standing loads, lots of idling to run equipment, racks and inventory that never come out. Killers: cooling systems, batteries/charging, rear suspension, tires wearing weird under load.
Delivery / distribution (cube vans, gas box trucks): near-GVWR loads, urban routes, hard duty on everything that stops and steers. Killers: brakes above all, front-end joints, driveline fluids nobody has ever changed.

Step 2: the schedule skeleton

Exact intervals get set per platform from its OEM severe-service table (that's part of my yard assessment) — but the skeleton below is what a working GTA van fleet keeps to, and it's the structure my PM visits are built around:

Checkpoint	Every PM visit	Watch it because…
Engine oil & filter	Changed — severe-service interval, per platform, tracked per unit	Fleet duty shears oil faster; stretched intervals are how engines age ten years in three
Brakes	Pads measured, rotors checked, calipers/slides eyeballed, readings logged	Loaded vans eat brakes; catching wear early is pad money instead of pads-rotors-caliper money
Tires	Pressures set, tread depths logged corner-by-corner, rotation as needed	Under load, pressure drift and alignment drift show up in the tread log before they kill the tire
Battery & charging	Battery health + charging output tested	Liftgates, telematics and short trips chronically undercharge fleet batteries — winter finds every weak one at 6 a.m.
Cooling system	Level, condition, leaks, hoses; deeper service by interval	Idle-heavy vans cook cooling systems; a $30 hose caught early is a $3,000 tow-plus-overheat avoided
Front end & suspension	Ball joints, tie rods, sway-bar links, springs/shocks checked under load	Load + GTA potholes = joint wear; it telegraphs in inspections long before it strands a route
Fluids & driveline	All levels topped; trans/diff/transfer condition by interval	The most neglected items in every fleet I've walked — nobody's ever changed them until something whines
Lights, wipers, horn	Full walkaround, bulbs on the spot	Two-dollar fixes — and exactly what roadside inspections flag first
Diesel extras (Sprinter & friends)	DEF topped, fuel filter by interval, emissions-system health noted	Modern diesels hate courier duty cycles; staying ahead is dramatically cheaper than reacting

Cadence: for most working fleets this lands as a PM visit roughly quarterly per unit, monthly for high-km courier units — set per fleet at the assessment, then it runs on autopilot: I track the intervals and show up. Every visit ends with a photo condition report per unit, which doubles as the maintenance record Ontario requires you to keep anyway.

Step 3: the two seasonal non-negotiables

Fall (Oct–Nov): winters/all-weathers on, batteries load-tested (winter kills the marginal ones), coolant protection verified, wipers/washer done. One yard visit, whole fleet winter-proofed.
Spring (Apr): summers back on, winter damage sweep — potholes will have moved something in the front end — and brakes checked after salt season.

Changeover runs $45/van on rims ($39 at 10+), and program fleets get first pick of the April/November yard days — those book out first, every year.

What this schedule is protecting, in dollars

One van off the road doesn't just cost the repair — it costs the route: a driver standing still, deliveries missed, a tow if it died on the 401, and an emergency-shop bill at captive prices. Against that, a $129–169 PM visit per van per quarter is not a cost centre; it's the difference between a scheduled $129 morning and an unscheduled $1,500 day. That's not a pitch, it's arithmetic — and it's why the biggest fleets in the country all run documented PM programs while the 8-van operations that can least afford a dead truck usually don't.
