Maintenance FAQs

For most diesel trucks, we recommend oil changes every 15,000-25,000 miles or every 6 months, whichever comes first. However, this can vary based on your engine type, operating conditions, and oil quality. Heavy-duty or severe service applications may require more frequent changes.

Our comprehensive PM service includes: fluid checks and changes, filter replacements, tire inspection and rotation, brake inspection, battery testing, belt and hose inspection, lighting check, suspension evaluation, and a full diagnostic scan to check for any trouble codes.

While some basic tasks like checking fluid levels or tire pressure can be done by owners, we recommend having a certified technician perform most maintenance. Modern trucks have complex systems that require specialized tools and knowledge to service properly. Improper maintenance can void warranties and lead to costly repairs.

Neglecting maintenance leads to reduced fuel efficiency, increased emissions, higher repair costs, and unexpected breakdowns. It can also create safety hazards and potentially void manufacturer warranties. Regular maintenance typically costs 3-5 times less than major repairs caused by neglect.
