About Us

Your Local Diesel Professionals in Maryborough

Core Diesel is your trusted one-stop shop for diesel repairs across the Fraser Coast. We provide reliable servicing and expert maintenance for domestic vehicles like 4WDs and small trucks, as well as heavy machinery and civil equipment.

Our team brings together a wide range of backgrounds and experiences, united by a shared commitment to quality. No matter what diesel-powered machine you run, we have the tools and knowledge to keep it going strong.

How we got here

It all started in 2013 when Jye Core opened Core Diesel in a 220 square metre shed in Maryborough. In the early days, the focus was on contract servicing for mines and large organisations across Queensland. With consistent hard work and high standards, the business steadily grew.

Today, Core Diesel operates with a team of 13, including one apprentice. Our main workshop now covers 864 square metres under roof, and we run a fleet of custom-built field service trucks. These purpose-designed vehicles are fully equipped to handle on-site repairs across the region.

We are proud to be the authorised Mack, UD and Volvo service agent for the Wide Bay area. This means we are trusted to perform warranty work on these vehicles. In 2020, we welcomed the local Ryco 24/7 franchise into the Core Diesel family.

Our Core Values

Our three core values are dependability, customer service and uniqueness.

Dependability

If you rely on diesel equipment to do the job, you need a team that delivers. Our technicians are hand-picked for their skill, and we invest in cutting-edge equipment to match.

We are equipped to carry out everything from complete engine rebuilds on large plant machinery to quick diagnostics and logbook servicing for your 4WD. No job is too big or too small – only important.

Customer service

Whether you drive a single ute or manage a whole commercial fleet, we treat every job with care and respect. We believe in fair pricing, clear communication and treating every client like a valued partner.

Uniqueness

We aim to be the only diesel repair service you will ever need. Keeping parts, tools, and technicians under one roof ensures consistent quality and faster turnaround. We stock amanyspares and offer upgrade options to improve performance and extend equipment life.

Giving back

At Core Diesel, we are proud to be part of the local community. As we have grown, we have stayed true to our roots as a friendly, reliable workshop supporting the people we serve.

We primarily focus on developing the next generation of diesel professionals and actively support apprenticeships and training opportunities.
