At Auto Service Experts Diesel, we specialize in light and medium duty diesel trucks, and have done so since 2000.

Ford Powerstroke, Dodge Cummins, and Chevrolet Duramax Customers:

You have heard the ads stating that a San Antonio car dealership's technicians are factory trained, but that does not guarantee a working knowledge of your diesel vehicle. Many factory trained techs are educated too broadly, without emphasis on the diesel vehicles that are of importance to you.

Fleet, Light and Medium Duty Diesl Customers:

Your commercial vehicle is your livelihood. We understand that a long down-time is simply not an option. We will make every attempt to provide the fastest turn-around while maintaining our high standard of customer satisfaction.

Our specialization in troubleshooting and service has earned us the reputation for efficient diesel repairs and service, in a timely manner, and at a fair price. We are experts in determining specific maintenance plans for each diesel vehicle.

By constantly researching recurrent factory problems and technical service bulletins, we can suggest service operations that will keep you rolling, and minimize your down-time.

Put your trust in real San Antonio Auto Service Experts Diesel Mechanics!


Diesel engine automobiles require special mechanics that are knowledgeable with these particular engines. This is especially true in the summer heat of Phoenix.

The diesel mechanics at Auto Service Experts are fully trained in diesel engines! Diesel engines are designed to give better fuel efficiency, but are known to pollute the air more. A proper maintenance schedule by the diesel mechanics at Auto Service Experts will reduce this potential pollution and improve power and performance.

Only trust a certified diesel mechanic to service your diesel engine. There are a great number of differences between a diesel engine and an internal combustion engine. Not using a trained diesel mechanic could lead to trouble for you down the road. The trained diesel mechanics at Auto Service Experts know diesel engines and will help with any repairs or maintenance that you require.
