Yes, you can . I prefer that oil, but if your engine runs better on 5W then it really doesn't make a lot of difference. Much more important is changing it regularly.
I totally disagree. If the designer and manufacture of your engine lists 5w30 as the recommended weight then why would you second guess them and use another weight. It will make a difference. If it did not make a difference then the manufacture would tell you to use whatever you prefer. Use 10w30 instead of the recommended 5w30 and your engine will suffer excess wear over time. You won't see any difference now but you sure will later on down the road.
for 4.0l/ 4.7l H.O. use 10w30 for 4.7l use either 10w30 or 5w30 but 5w30 is preferred
