Choosing diesel mechanics in Australia

Diesel mechanics for diesel servicing and repairs, injectors and fuel systems, DPF cleaning and truck repairs. Mechanics Directory lists 3,233 diesel mechanics in Australia. Listings show the services each business offers, and a rating where there is one.

What to check before you book

Getting started

  1. Describe the job. Your vehicle's make, model and year, what's wrong or what it needs, and when you need it done.
  2. Shortlist two or three. Use the filters above to narrow this page by listed credentials and website.
  3. Compare quotes. Or send one request and we'll match it with up to 3 diesel mechanics.
  4. Agree in writing. Confirm the price, what's included and when the vehicle will be ready before work begins.

Frequently asked questions

How do I choose between diesel mechanics in Australia?

Compare two or three. Ask whether they work on your make, and on light vehicles, trucks or machinery, whether they can come to you, and for a written quote for parts and labour. A business that is owner verified on Mechanics Directory has confirmed it runs the listing.

How much does a diesel service cost in Australia?

It depends on the vehicle or machine, the oil and filters it takes, and whether the injectors, turbo or DPF need work. Asking two or three local diesel mechanics for a written quote is the quickest way to see the going rate in Australia.

Do diesel mechanics need to be licensed?

Licensing depends on the work and the state. Modifications such as GVM upgrades need certifying under your state's rules, and outside Western Australia and the Northern Territory, modifications to heavy vehicles over 4.5 tonnes are regulated by the National Heavy Vehicle Regulator. Motor vehicle repair businesses must be licensed in New South Wales, Western Australia and the ACT. Elsewhere, ask the business which qualifications and licences apply to your job. Listings marked "Credentials listed" show a licence, accreditation or membership on the business's profile. We don't check it, so confirm it with whoever issued it.

What is DPF cleaning?

A diesel particulate filter (DPF) traps soot from the exhaust and burns it off on longer runs at highway speed. Lots of short trips can stop that happening, so the filter blocks and a warning light comes on. A diesel mechanic can check the filter and clean it or run a forced regeneration.

What does "serves this area" mean?

Some businesses are based in a nearby suburb but cover this area, including mobile mechanics and towing services that come to you. On suburb pages we list businesses based in the suburb first, then the ones that say they serve it.

How do free quotes work?

Tell us about the job once. We match your request with up to 3 diesel mechanics near you. A business on a paid plan here gets it with your name and contact details and can contact you directly. A business on the free plan sees the job and your suburb but not your details, so it can't contact you unless it upgrades. A business that hasn't claimed its listing sees your request only once it claims. After you send, we tell you which applies to each business. It's free and there's no obligation.
