*: 5W-30 is preferred.
Engine oil viscosity (thickness) affects fuel economy. Oils of lower viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is required to properly lubricate the engine.
Recommended grade and viscosity under severe driving conditions
If the vehicle is used in desert areas, in areas with very high temperatures, or is used for heavy-duty applications, use of oil with the following grade and viscosities is recommended.
API classification SM (or SL):
SAE viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50
