Hi, welcome to Just Answer.

SAE 5W-30 is best for your vehicle. However, you can use 10W-30 if the outside temperature is higher than 18°C (0°F). Do not use other viscosity oils, such as SAE 20W-50.

NOTICE: Using oils of any viscosity other than those recommended could result in engine damage. When choosing an oil, consider the range of temperatures the vehicle will be operated in before the next oil change. Then, select the recommended oil viscosity.
