Sorry to revive this old thread, but I am a bit confused and prefer to stay within spec while under warranty. I switched to 0w30 for my 1500 mile change. The manual specifies 0w20 or 0w30. When I went to take the car to the dealer for it's first included oil change they would not use 0w30 because they said spec is 0w20. Which is it?

Thanks all
