Average Salary of Diesel Service Technicians and Mechanics

What diesel service techs and mechanics earn.

Diesel engines have long been used in trucks and buses as well as in cars. Diesel acceptance among US car consumers has been mixed with too many people still remembering the poorly designed GM engines of the 1970s and 1980s that were notorious for failing.

These days, car manufacturers are producing diesel engines that are not simply powerful and fuel efficient, but are clean burning. Servicing this growing contingent of diesel-powered cars are diesel service technicians and mechanics.

The US Bureau of Labor Statistics (BLS) has some interesting data to share about these professionals and their chosen field.

Approximately 291,600 people were employed as diesel service technicians and mechanics in 2022 according to the U.S. Bureau of Labor Statistics.

The median wage for these professionals came in at $54,360. Those in the 10th percentile earned $37,030 or less per year on average while those in the 90th percentile earned $78,340 or more.

The BLS notes that most employers of diesel service technicians and mechanics expert job candidates to have at least a high school diploma or its equivalent. While in high school, students should take courses in automotive repair, electronics and mathematics.

To handle diesel repair, many employers look for people with extensive experience, including graduates of vocational programs or community colleges. Hands-on training that includes handling basic parts to engine deconstruction is usually preferred.

Certification from the National Institute for Automotive Service Excellence can be advantageous and may be required especially by better paying employers.

Job Outlook

The BLS has forecast little to no change in the number of related jobs from 2022 to 2032. Some 24,300 job openings have been projected for each year mainly due to retirements or those workers who transfer to another occupation.

Much of the increase in job openings will come by handling the nation’s growing truck fleet. Tougher federal emissions requirements mean that some older trucks will need to be retrofitted. Even so, the durable nature of these engines also means that demand for new people may be limited.

Candidates should also keep a close eye on the passenger vehicle market too. GM, Ford and Chrysler have long used diesel engines in their pickup trucks, but all three are also following their European competitors by introducing diesels to other models including sedans and SUVs.

These new models will be needing servicing at some point, quite possibility fueling interest for a new crop of talented technicians.
