Recommended grade and viscosity

Use only engine oil with the recommended grade and viscosity.
Refer to “Engine oil”.
NOTE
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.
