Frequently Asked Questions

If you don’t find what you’re looking for, feel free to reach out—we’re happy to assist!

  • What is included in a professional semi tractor oil change and preventive maintenance service?

    When you bring your semi tractor to us for preventive maintenance, we perform a comprehensive service designed to maximize engine longevity. Our team handles a complete oil and filter change using premium conventional or synthetic oils like Shell Rotella, Mobil Delvac, or Chevron Delo, depending on your preference. We also perform a full chassis greasing, top off your coolant and windshield washer fluid, check tire air pressure, and inspect oil levels in all three crucial boxes: the engine, transmission, and differential. This detailed approach ensures every vital system is protected and ready for the long haul.

  • How often should I get a commercial truck fluid and chassis grease service?

    To prevent costly breakdowns and extend the life of your commercial vehicle, we recommend scheduling a chassis grease and fluid check during every routine oil change. Regular greasing protects vital steering and suspension components from friction and road debris, while checking fluid levels prevents severe component wear. Our team meticulously inspects the oil levels in your engine, transmission, and differential boxes during every preventive maintenance visit. Keeping these components properly lubricated and topped off ensures your truck operates safely, improves fuel efficiency, and helps you avoid unexpected and expensive roadside repairs during transport.

  • Do you offer different oil brands and viscosity options for heavy-duty trucks?

    Yes, we understand that different engines have unique lubrication requirements, which is why we offer a wide range of options. We carry premium conventional and synthetic oils from industry-leading brands, including Shell Rotella, Mobil Delvac, and Chevron Delo. Depending on your manufacturer specifications and driving conditions, you can choose from various viscosities such as 15W-40, 10W-30, and 5W-40. Our knowledgeable technicians are always available to help you select the best oil type to optimize your engine performance, protect vital components, and ensure maximum fuel efficiency for your semi tractor.

  • Do you have secure parking and other amenities for truck drivers?

    Absolutely. We recognize that safety and convenience are major concerns for drivers, which is why we provide secure parking at our facility. While your commercial vehicle is with us for diesel diagnostics, oil changes, or preventive maintenance, you can rest assured that your truck and cargo are safe. We aim to be the ultimate resource for local and passing truck drivers in the area. Our facility is designed to offer peace of mind, allowing you to focus on your schedule while we handle the maintenance and care of your heavy-duty rig.
