The OP should read his owner's manual - it would answer all his questions - but you guys shouldn't be telling him things that could potentially void his warranty, either.

Ironic you're complaining about misinformation...

Use SAE 0W-40 viscosity grade engine oil.
When selecting an oil of the appropriate
viscosity grade, it is recommended to select
an oil of the correct specification. See
“Specification” earlier in this section.
If 0W-40 dexos2 oil is not available, SAE
5W-30 dexos1 full synthetic engine oil may
be used for street use
