Why You Need A Diesel Mechanic
Nov 28, 2022
No matter what type of engine you have, it goes without saying that regular servicing is an essential part of vehicle maintenance. If you have a diesel engine, you need a mechanic that understands how these engines work and what they require to keep performing at their very best.
Regular servicing from a diesel mechanic will help you avoid the need for unexpected (and expensive) repairs. In this blog, we’ll break down what makes diesel engines so particular and why you should work with a diesel mechanic every time.
What is a diesel engine
To put it simply, diesel engines run on diesel fuel rather than petrol. Diesel engines can most commonly be found in vehicles such as buses, trucks and 4WDs, as they tend to require more power than your average car due to their weight or their ability to drive through extreme terrains.
As well as being more powerful, diesel engines come with higher fuel efficiency than regular engines. This is because they burn fuel in a way that allows for less energy to be lost, helping to keep operating costs down for larger vehicles that tend to use more fuel.
Diesel engines are more complex
Diesel engines are more complex than petrol engines, with many more different components that can break down if not catered for properly. Elements such as turbochargers, fuel injection systems and diesel particulate filters are not found in petrol engines and therefore some mechanics may be unfamiliar with them.
Also, many of the vehicles that are likely to have diesel engines come with much more compliance laws and regulations required to keep them safe and up to standard. This means you’ll want to work with a car service mechanic who understands the ins and outs of your diesel engine and how to keep your vehicle operational.
Diesel mechanics can work on multiple types of vehicles

As we’ve already mentioned above, diesel engines are most commonly used to power heavier, stronger vehicles. This means that your diesel mechanic will likely have experience and expertise in a wide variety of vehicles and machinery, including:
- Transportation vehicles (semi-trucks, buses and 4WDs)
- Commercial generators (used for backup power for hospitals, apartment buildings and commercial buildings)
- Agricultural equipment (tractors, irrigation pumps and harvesting machines)
- Construction equipment (cranes, pavers and road rollers)
Diesel mechanics understand how diesel engines work
When you work with a diesel mechanic, you work with someone who knows how to troubleshoot and fix problems across an incredible range of different vehicles and machines. Diesel mechanics also tend to be very strong communicators, as many of their customers don’t have the same level of technical expertise regarding their vehicles’ engines.
Diesel mechanics are able to explain the situation at hand and what needs to be done next in a clear and easy-to-understand way, giving you peace of mind regarding any repairs that need to be performed. They will also know the ins and outs of diesel maintenance, which include:
- Checking gaskets for leaks
- Inspecting glow plugs
- Changing fuel filters
- Changing air filters
- Maintaining coolant levels
- Oil and oil filter changes
