Diesel Mechanic vs. Auto Mechanic: Which Career Path Is Right for You?

When it comes to choosing a career path in the automotive industry, it helps to know more about what options are available to you.

Both diesel mechanics and auto mechanics play important roles in keeping vehicles on the road and in good shape. While both are trained to repair and maintain vehicles, their areas of expertise will vary.

Diesel mechanics have a specialization in diesel engines, which are used not only on vehicles but also for commercial equipment, like what is seen in manufacturing and agricultural fields.

If you’re not sure which area you’re more interested in, keep reading to learn more about the different roles and types of training for each that may help make your decision clearer!

What Is a Diesel Mechanic?

Diesel engines are used for some of the biggest industries across the country, including construction, manufacturing and mining.

Diesel mechanics are responsible for keeping these engines working properly by performing inspections and repairs on the vehicles that have diesel engines. They also commonly maintain other types of equipment that utilize diesel engines and technology.

It’s important to have the right skills for this job. Employers typically prefer applicants who have some sort of hands-on experience and formal training, which you can get from a trade school like Universal Technical Institute (UTI).1,18

The 45-week Diesel Technology program is designed to mirror the training techs receive in the industry and teach hands-on skills that translate to the workforce.7

What Is an Auto Mechanic?

Cars get us from Point A to Point B, and when repairs need to be made, auto mechanics are the ones who answer the call.

Auto mechanics, also referred to as automotive technicians, are consistently working on and maintaining different types of vehicles. From routine maintenance to engine replacements, the work of an automotive mechanic can vary.

They possess in-depth knowledge on different car systems and how they work together to help a vehicle run. From dealerships to independent shops, auto mechanics work in various types of environments.

Getting hands-on experience and training from a trade school like UTI can help you feel ready to enter the job market.18 UTI offers a 51-week Automotive Technology program that builds knowledge from the ground up so that grads are prepared for the industry.7

Differences Between Diesel Mechanics and Auto Mechanics

Both diesel and automotive mechanics are skilled professionals within their spaces. Diesel mechanics are focused on servicing larger, heavy-duty vehicles that are powered by diesel engines in comparison to automotive mechanics that handle a wider range of gasoline-powered vehicles.

When it comes to education, while neither career path requires a formal education, having some sort of background knowledge and experience could be helpful. Attending a trade school program like those offered at UTI can help graduates stand out when compared with candidates with no formal training.

As far as demand goes, both diesel mechanics and automotive mechanics are needed. Employers are looking for skilled mechanics in both sectors to perform maintenance and repairs of gasoline or diesel-powered engines.

According to the Bureau of Labor Statistics (BLS), total auto technician employment is expected to exceed 794,000 by 2032, and total diesel technician employment is expected to exceed 294,000 by 2032.47,48

When it comes to salary compared between the two, according to the BLS, the median annual salary for automotive service technicians and mechanics in the United States was $47,770 in May 2023, and the median annual salary for bus and truck mechanics and diesel engine specialists in the United States was $58,970 in May 2023.25,29

This means half of automotive technicians as well as half of bus and truck mechanics and diesel specialists earned more, and half earned less. Keep in mind that salary depends on several factors, including experience, employer, demand and cost of living in the area.

Choosing the Right Career Path

When it comes to deciding between a career as a diesel mechanic or auto mechanic, the choice really comes down to what you’re most interested in.

Do you have a passion for big engines and lots of power? You’re likely going to enjoy choosing the route of a diesel mechanic.

If you like a lot of variety and wrenching on different vehicles, a career as an automotive mechanic might make more sense.

When deciding, researching more about each role can make a big difference, as well as reading about the experiences of those who work in the industry. We have all kinds of stories on our blog from both diesel and automotive graduates!

If you still are having a hard time deciding, it’s worth noting that many UTI campuses offer a combined Automotive & Diesel Technology program – so you can learn the best of both worlds!
