How Much Does a Diesel Mechanic Make a Year?

Even if you haven’t thought about diesel mechanics before, chances are you’ve benefited from their expertise. These skilled technicians fix the machines that harvest our food, the generators that provide electricity when the power goes out, the big rigs that ferry our goods across the country, and so much more.

Being a diesel mechanic requires a certain skill set and level of training. Generally speaking, they tend to earn slightly more than auto mechanics. According to the latest figures from the U.S. Bureau of Labor Statistics (BLS), the median pay for a diesel mechanic is $59,920 per year, or $28.81 per hour. (By comparison, the median pay for an auto mechanic is $51,940 per year, or $24.97 per hour.) However, pay rates can vary depending on where a technician works and their level of experience.

Key Points

•   Median annual pay for diesel mechanics is $59,920, ranging from $39,020 to $82,430.

•   Earnings vary by location, experience, and type of vehicles worked on.

•   Job responsibilities include inspecting, repairing, and maintaining diesel engines, and communicating with customers.

•   Benefits often include health insurance, 401(k), paid time off, and tuition reimbursement.

•   Pros include a comfortable median pay and potential for higher earnings; cons include lower pay in high-cost areas and limited additional income opportunities.

What Is the Starting Salary for a Diesel Mechanic?

If you’re just starting out as a diesel mechanic, you probably won’t earn the median salary of $59,920. According to the BLS, 10 percent of workers — most likely those new to the field — earn closer to $39,020, or $18.76 per hour. In some states, this rate is only a few dollars more than minimum wage.

Whether you’re paid a set weekly salary or hourly rate, starting out as an entry-level diesel mechanic can be challenging. The wages may be difficult to live on, especially if you have a lot of financial obligations or live in a place with a higher cost of living.

But if working with machinery and, in particular, on diesel engines is what you really want to do, it can be worth any initial sacrifices. And the good news is, diesel mechanic jobs are expected to continue to grow. So in time, you can move up the ladder or seek out a new job to increase your yearly salary.

What Do Diesel Mechanics Do?

Diesel mechanics inspect, repair, and maintain vehicle engines that run on diesel fuel. This includes everything from trucks, overhaul buses, and trains, to cruise ships, generators, and construction and agricultural equipment. Their goal is to make sure vehicles are safe for both drivers and passengers.

A diesel mechanic position is a manual labor trade job you can get without a college degree, though most employers want diesel techs to have at least a high school diploma or a GED equivalent. While you don’t need secondary education to do the job, you do need specialized training, which can be acquired on the job, through a certificate program, or by attending a trade or vocational school.

And though diesel mechanics may need to occasionally speak with customers about issues with the vehicles, it can be a good job for introverts.
