Engine oil selection
Use API SH, Energy±Conserving II multigrade engine oil or
ILSAC multigrade engine oil.
Recommended viscosity (SAE):
SAE 5W±30 is the best choice for your vehicle, for good
fuel economy, and good starting in cold weather.
If you use SAE 10W±30 engine oil in extremely low
temperatures, the engine may become difficult to start,
so SAE 5W±30 engine oil is recommended.
