At Dunstall Diesel Services, we are a proud family-owned business built on trust, quality, and commitment. Based in Adelaide, we provide reliable, professional, and comprehensive mechanical solutions to individuals, businesses, and industries across South Australia. Our team understands the importance of keeping your vehicles and equipment running at their best — because when your machines stop, so does your livelihood.

From the very beginning, our family has been dedicated to providing honest, dependable service with a strong focus on craftsmanship and safety. Over the years, we've grown alongside the community we serve, building lasting relationships with local businesses, fleet operators, tradies, and everyday drivers who rely on us for both routine maintenance and urgent repairs.

We specialise in heavy vehicle servicing and repairs, ensuring trucks, trailers, and commercial fleets stay compliant and on the road. Our expertise also extends to 4WDs, cars, earthmoving equipment, marine engines, and cranes — supporting industries from transport and construction to agriculture and marine.

What truly sets us apart is our ability to provide 24/7 mobile breakdown support. With fully equipped service vehicles, we come directly to you — whether you're stuck on the roadside, at a job site, or need after-hours assistance to get moving again.
