Recommended viscosity (SAE):
In extremely cold weather, SAE 10W -
30 oil or oil with higher viscosity may
cause difficulty to start the engine, so
SAE 5W-30 engine oil is
recommended.

SL. SAE viscosity is indicated at the
middle of the label, such as 10W-30.
―Energy-Conserving‖ symbol at the

can save engine oil.
Certification of ILSAC (International
Lubricant Standardization and
