Maintaining a pickup truck involves regular checks and care to preserve its performance, durability, and towing capability, ensuring it handles both daily use and heavy-duty tasks. Start with the engine: change the oil every 5,000-7,500 miles (or as specified in the manual) using the recommended viscosity, as clean oil protects engine components from wear, especially critical for pickup trucks that often tow or carry heavy loads. Inspect and replace air filters every 15,000-30,000 miles to ensure proper airflow, which improves fuel efficiency and engine performance. For the transmission, check fluid levels monthly and change the fluid according to the manufacturer’s schedule—this is vital for pickup trucks used for towing, as heat can break down transmission fluid over time. Tire maintenance is key: rotate tires every 5,000-7,500 miles to ensure even wear, check pressure weekly (including the spare), and replace tires when tread depth falls below 4/32 of an inch to maintain traction, especially important for pickup trucks navigating rough terrain. Brake checks are essential too; inspect brake pads and rotors every 15,000 miles, as pickup trucks’ heavier weight puts more strain on braking systems. Don’t overlook the undercarriage—wash it regularly to remove salt, mud, and debris that can cause rust, particularly if the pickup truck is used in snowy or off-road conditions. Finally, follow the manufacturer’s maintenance schedule for additional checks, such as on the suspension, steering, and electrical systems, to catch issues early. With consistent care, a pickup truck will remain reliable and capable for years.
