There is a SIB out on this and I suspect many if not most dealers have already made the switch.

many dealers have already made this switch. however, my 2011 manual specifies 5w30/5w40 and makes no mention of a zero weight.
if you havent noticed the trend, all modern vehicles are now making the switch to a 0w, but this is only in north america due to the CAFE requirements. please look it up if you are interested. to sum it down quickly, 0w-20 is now widely used in new vehicles for a roughly 0.2mpg increase which when added up with every vehicle a manufacturer makes is a notable difference.

yes, you read that right. 0w oils are spec'ed purely for fuel economy purposes, with absolutely zero concern taken into consideration for rod bearing protection which in turn will suffer. driving aggressively with a 0w in your engine is death to rod bearings.
