ENGINE OIL SELECTION
Use API grade SJ “Energy−Conserving”,
SL “Energy −Conserving” or ILSAC multi-
grade engine oil.
Recommended viscosity (SAE):
OIL05u
SAE 5W30 is the best choice for your
vehicle, for good fuel economy, and
good starting in cold weather.
If you use SAE 10W30 engine oil in
extremely low temperatures, the engine
may become difficult to start, so SAE
5W30 engine oil is recommended.
