FAQs

How long do diesel engines usually last?

Diesel engines are known for their durability and can last anywhere from 300,000 to 1,000,000 miles or more with proper maintenance. Factors such as regular oil changes, clean fuel, and proper engine tuning can significantly extend engine lifespan, ensuring reliable performance for years to come.

What are common signs of engine issues?

Common signs of engine problems include excessive exhaust smoke, loss of power, engine knocking or pinging noises, rough idling, and abnormal engine vibrations. If you notice any of these symptoms, it's essential to have your engine inspected by a qualified technician to prevent further damage and ensure optimal performance.

What causes a diesel engine to lose power?

A diesel engine may lose power due to dirty fuel filters, malfunctioning turbochargers, or clogged EGR valves. Regular preventive maintenance, including fuel filter changes and system inspections, can help prevent power loss.

"William is a awesome guy. He did a great job. Called about the tandem axle not sliding and helps me fixed some other little issue. I definitely recommend austin fleet services"

Jackson Epalle

"These guys are great, had an emergency with a DEF pump on a black Friday, only shop that picked up the phone, took my driver in immediately and didn't give me the runaround like most do now. I asked not to diagnose anything and just change the pump. Truck back on the road in 3-4 hours and saved us at least 3 days waiting for another shop to open. Definitely coming back here next time our  trucks are in the area!"
