Diesel Oil Change & Preventive Maintenance in Jackson, MS
Wilkerson's runs same-day diesel oil changes and preventive maintenance at our Jackson, MS shop on US-49. Manufacturer-spec oil, OEM filters, full PM checklist — for owner-operators, fleets, and diesel pickups. Walk in or schedule, you're usually back on the road the same afternoon.
PM isn't an oil change. PM is the truck staying on the road another 100,000 miles. We use the manufacturer interval and the manufacturer-spec oil for your engine — not the cheapest jug on the shelf. We check filters, fluids, belts, hoses, brake adjustment, air leaks, wheel seals, and lighting on every PM visit by default. That's the boring stuff that catches problems before they catch you.
Open Saturday 7am–noon for PM service. A lot of owner-operators come in Saturday morning to keep the truck running during the week — and we keep a bay open for them.
What's included
Everything we do on a oil change & pm visit.
Manufacturer-spec oil change
15W-40, 10W-30, synthetic blends — whatever your engine calls for. Not the cheapest, the right one.
Oil & fuel filter replacement
OEM-spec filters. Fuel filter at the right interval keeps injectors alive longer than the engine warranty.
Air filter check & replacement
Inspected every visit. Replaced when restriction or fouling demands it.
DPF & coolant filter service
Where applicable. DEF level top-off included.
Full fluid level & condition check
Coolant, DEF, brake fluid, transmission fluid, power steering, washer.
Belt & hose inspection
Cracks, glazing, swelling. A $40 belt now beats a $4,000 tow later.
Brake adjustment & wheel-end check
Auto-slack measurement, wheel-seal visual, chamber inspection. Free at every PM.
Lighting & reflector check
Cheapest DOT pass insurance there is. We replace bulbs on the spot if you want them done.
Fault-code pull
We scan for soft codes that haven't lit the dash yet. Catch the failure before the derate.

Most PM visits are 1–2 hours. Walk in before noon Monday–Friday and you're back on the road the same afternoon.
Saturday morning is open. A lot of owner-operators run their PM Saturdays so the truck runs all week.
Brakes, fluids, belts, hoses, lights, fault codes — checked every visit by default. That's how PM keeps trucks earning past 800,000 miles.
Frequently asked

Most PM visits run 1–2 hours including the full PM checklist (not just oil and filter). If we find something during the visit that needs attention, we'll quote it before we touch it.
Walk-in is fine Mon–Fri 7am–5pm and Saturday 7am–noon. Calling ahead helps us pre-stage your oil and filter — same-day either way.
Manufacturer spec — varies by engine family and duty cycle. We stock the right oil for Cummins, Detroit, CAT, Paccar, Duramax, Power Stroke, and the medium-duty diesels. Synthetic vs. conventional is a duty-cycle conversation — we'll tell you straight what fits your truck.
Manufacturer interval, by miles or engine hours, depending on what comes first. Class 8 over-the-road typically 15,000–25,000 miles. Diesel pickups under heavy load shorter. We track it on your service log so you don't have to.
Yes. Fleet PM accounts get scheduled intervals tied to engine hours/miles, priority bay time, consolidated monthly billing, and a dedicated contact. Call to set one up.
