Diesel Service FAQs

What diesel vehicles do you work on?

We service most light-duty diesel pickups, vans, and SUVs from popular brands such as Ford, Ram, Chevrolet, GMC, and others. If you are unsure about your vehicle, give your local Main Street Auto a quick call, and we will confirm before you schedule.
How do I know my diesel needs service?

Common signs include longer crank time before starting, rough idle, loss of power when towing or climbing hills, increased smoke, poor fuel economy, or a check engine light. If something feels off or sounds different, it is best to have our mechanics take a look before it gets worse.
How often should I change the oil and fuel filters on a diesel vehicle?

Most diesel engines require more frequent oil and fuel filter changes than gasoline engines, especially if you frequently tow, idle, or drive in dusty conditions. We can review your owner’s manual and your driving habits, then create a maintenance schedule tailored to how you actually use your truck.
Can you fix diesel emissions and DEF system problems?

Yes. Our mechanics diagnose faults in EGR, DPF, SCR, and DEF systems, as well as related warning lights and reduced power modes. We will explain what failed, why it happened, and what options you have to get your diesel running properly again.
Does your warranty cover diesel repairs?

Most diesel services and repairs are backed by our 24 month, 24,000 mile warranty, so you can leave knowing your investment is protected. Certain parts or services can have different coverage, and we will always review the details with you before you approve the work.
