Question 5w30 or 10w30???

hey, i've read several posts in which both grades were used...so which is it???

i recently switched to mobil 1 synthetic 5w30. i asked the dealer guy what i should use, and he said 5w30...however, some of you here are using 10w30...what's the difference? weight of the oil right??? doesn't the choice depend on variables such as temperature, driving style, etc.?

ever since i switched to mobil 1, my car has been running smoother (albeit louder...for some reason, the engine sounds more raucous...must be the k&n panel filter???).

anyone got any words of wisdom?

thx,
