Starts up strong in cold weather and doesn't knock. 5w30 and 10w30 are the same in weight, meaning that at a certain operating tempature, they are both going protect equally when the car is at operating tempature. The number in front of weight basically means, how well it can circulated oil on cold start ups. So basically having 0w30 is better than 5w30, and protects just as well as 5w30, because your looking at there weights.I highly suggest not running 10w30 in the winter because oil will not travel fast enough on start up making the engine sound extremely noisy for the first couple seconds, and the first couple seconds is very crucial because everyone knows that wear and tear is at its peak on start up.</blockquote>
