About Us

Since 1968, L & J Diesel Service, Inc. has steadily grown in size, customer base and diversity. Our reputation is wide spread as an innovative company of dedicated professionals who can be relied upon for superior craftsmanship, quality product lines and responsive service.

L & J Diesel Service, Inc. began in Miami with one employee, the founder Luis M. Cueto, and only one test stand. The company moved to Jacksonville in 1974 and grew rapidly, relocating in 2014 to a new specially designed and fully equipped facility.

Our growth and diversity is continuing with many employees and more than 10 test stands including a high tech computerized 100 hp EPS 815 Bosch calibration test stand for the most powerful and accurate testing available anywhere.

Today, L & J Diesel Service, Inc. is the largest, most diverse, and complete independent diesel engine parts shop of its kind in the southeast.

Our Mission is to continue to provide our customers with competitively valued, quality products and service, at a level of excellence which establishes the standard for our industry.

This will be accomplished by being sensitive to changing customer and market needs, and positively responding to these changes with innovative approaches developed by involved employee/owners.

Our Philosophy is that we are all important members of a team of employees/owners that will, by utilizing our individual strengths in a cooperative group effort, achieve our Mission and Purpose.

We encourage a climate of open communications for sharing of ideas, and in so doing, provide opportunities for individual growth, increased responsibility, and personal satisfaction.
