Diesel Servicing Maryborough
Comprehensive Servicing, Repairs & Diagnostics for All Diesel Vehicles
If you need diesel servicing in Maryborough or across the Fraser Coast, you’re in the right place.
At Core Diesel, we do more than oil changes — we deliver complete, professional diesel care that keeps your ute, 4×4, or truck running at its best.
Whether it’s a routine logbook service, injector testing, DPF cleaning, or a full engine inspection, our local diesel mechanics get it done safely and properly — no shortcuts, no upsells, just solid workmanship you can trust.
Why Diesel Servicing Matters
Modern diesel engines are built tough, but Queensland conditions are even tougher.
Heat, dust, towing and long hauls all put extra stress on your engine — and missing a scheduled service can mean more wear, more fuel use, and more costly repairs later.
At Core Diesel, every service is done with the same precision we use for our dyno tuning — because reliability starts with maintenance.
