Engine oil selection
Use API SJ, "Energy–Conserving" multigrade engine oil
or ILSAC multigrade engine oil.
Recommended viscosity (SAE):
62L005–1
Temperature range anticipated before next oil change
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.
