* For normal operating temperatures (moderate climates): 10W-30 is usually recommended.
* For colder climates: A 5W-30 might be preferred for easier cold-weather starting.
* For hotter climates: A 15W-40 might be suitable, though 10W-30 is often acceptable unless you are towing heavy loads frequently at high temperatures.
Always check your owner's manual. The manual will specify the exact recommended oil viscosity and the API service classification (like SJ, SL, SM, etc.). Using the wrong viscosity can harm your engine.
