ENGINE OIL SELECTION
Use API grade SH, "Energy−Conserving II"
or SJ, "Energy−Conserving" multigrade en-
gine oil or ILSAC multigrade engine oil.
Recommended viscosity (SAE):
SAE 5W−30 is the best choice for your
vehicle, for good fuel economy, and

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.
