FAQ
Frequently asked questions
It depends on the engine, the oil and how hard the truck works. Diesel pickups often run 5,000 to 10,000 miles between changes, while heavy duty trucks can go much longer on the manufacturer schedule. Towing, idling and short trips shorten the interval. We follow your engine maker’s recommendation.
We use diesel rated oil that meets the specification your engine maker calls for, such as API CK-4, in the correct weight for your engine.
Coolant wears out over time and can lose its protection against corrosion and cavitation, which can damage liners, water pumps and radiators. A flush with the correct coolant type protects the cooling system.
Yes. We look over belts, hoses, leaks and other fluid levels and let you know if anything needs attention.
We work on light, medium and heavy duty diesel trucks, fleet vehicles, trailers and RVs, including Freightliner, International, Peterbilt, Kenworth, Volvo, Mack, Hino, Isuzu, Ford Power Stroke, Ram Cummins and GM Duramax.
It depends on the truck, the parts and what we find. We diagnose first, then explain the repair options and the price before any work begins, so there are no surprises. Call, text or use the form to get started.
