* 5W-20: This is likely the recommended weight for most climates and is often the best choice for fuel efficiency.
* 5W-30: This is a good option for warmer climates or if you tow heavily.
* 10W-30: This is a heavier weight and might be suitable for extremely hot climates, but is less common now. It's less fuel-efficient.
Always check your owner's manual. The manual will specify the exact recommended oil weight and viscosity grade for your specific truck's engine and operating conditions. Using the wrong weight oil can damage your engine.
