According to the owner's manual, what's the motor oil grade that is recommended?

Just want to get some sythetic before I pick up my silver IS

i would warn you about using synthetic in your new car. i would highly suggest waiting until at LEAST 5K miles....

My service guy told me to wait at least 10,000 miles before putting in synthetic. He said, "The engine is way too new for synthetic."
