the underside of the hood has a little graph/chart thingy.
it says you can use 5w30 for all temperature ranges, and 10w30 for 32* and up. so if you live in the south you can use 10w30, but its just too thick for cold winters.
personally, i would reccomend using 5w30. improves gas mileage a smidge but more importantly it cuts down on startup wear. 10w30 is to thick to get to all the places it needs to be on startup, thus causing wear. 5w30 will get there faster and reduce the wear.
